Warp Speed

Learning is so multi-faceted these days. There are so many ways to learn – one of the easiest is to simply google the subject matter – and a long list of possible information sources is immediately available.

On top of that, there are webinars, wikis, and professional blogs, amongst others.

It is true that structured learning is necessary to instil the traits of logical enquiry and critical thinking as they will serve students of the sciences well in their future careers. Educational institutions impart the foundations upon which the individual can pursue lifelong learning.

But how to produce a world class workforce? Is our educational system still relevant in the face of changing technology? What is the role of educators in light of such rapid technological developments? What skills are our engineers equipped with and what knowledge will be relevant when they graduate?

I s i t b e t t e r t o c r a m f u t u re engineers with all the knowledge they can absorb within a four year period, or is it better to significantly reduce the time it takes them to get qualified as engineers? They can be out in the field much earlier, but with serious options and systems in place to pursue lifelong learning.

How many biomedical engineering, aerospace, machining, chemical, electronics or mechanical engineers do we need four years from now, when the current cohort graduates? Are they primed to ride the next technology wave – or will they be limited by their choices? What is the next technology wave? Do grades matter if the subject matter doesn’t?

It is heartening to note that there is an increase in collaboration between educational institutes – not just universities but polytechnics, and vocational training institutes as well. The recent ABB technology fair at sprawling futuristic ITE Simei campus, in Singapore, shows that future specialists are being exposed to industry relevant, state of the art technology, early in their careers. This bodes well for the future development of the industry and the individual.

Educational institutions impart the foundations upon which the individual can pursue lifelong learning.

A complete line of radar instruments Radar is our world VEGA Grieshaber KG is a worldwide leading company in level, pressure and switching instrumentation. In 1997 VEGA introduced the first twowire radar instrument to the world. Two years later, VEGA advanced to international market leader in level measurement with radar. As far as liquids are concerned, radar has become accepted meanwhile as the standard technology – and with the radar instruments of ERA II, VEGA has set a new standard for continuous measurement of bulk solids.

Radar – ideal for bulk solids measurement VEGA radar technology covers virtually all areas of application with bulk solids. Thanks to non-contact measurement, both instruments are absolutely wear and maintenance-free. The wide dynamic range of the sensor ensures reliable measuring results, absolutely free of influence from strong dust generation. Even under the difficult conditions of pneumatic filling and the associated noise there is no signal degradation.

The instruments are Dust Ex and Gas Ex approved.

VEGAPULS 67:

Universal and cost-effective VEGAPULS 67 was developed for applications in which ultrasonic technology was primarily used until now.

VEGAPULS 67 offers superior measurement reliability at very low cost The performance of VEGAPULS 67 is unaffected by air turbulence and noise as they commonly occur during pneumatic filling. Even strong dust generation and temperature fluctuations do not influence the measuring results.

VEGAPULS 67 operates contactlessly and is therefore also suitable for applications in chemically corrosive products. VEGAPULS 67 is thus applicable in virtually all areas of production and represents more than just an alternative to ultrasonic technology due to its price-performance ratio.

VEGAPULS 68:

For the most demanding application conditions VEGAPULS 68 delivers reliable level data even in high temperatures, such as e.g. in steel production.

Technical Data VEGAPULS 67

The dusty conditions in the coal processing facilities of power plants or in building materials storehouses do not bother VEGAPULS 68 in the least.

The wide dynamic range of the sensor also opens up new possibilities in applications with powders and granulates in the food and chemical industries.

MARKETS

DCS Market Up 14 Percent US: In a recent ARC study entitled ‘Distributed Control Systems Worldwide Outlook,’ ABB takes the leading worldwide market position in this core automation market. The study reveals that total worldwide market for DCS increased by 14 percent between 2005 and 2006, with total revenues of US$13.4 billion, and forecasts that the compound annual growth rate for this market through 2011 will be 9.9 percent.

The ARC report states that the DCS market is a leading indicator of the overall health of the process automation business; overall growth in 2006 exceeded expectations.

Factors contributing to this upward trend include high energy prices and the growing worldwide demand for energy, as well as the continued need by manufacturers to improve their plant operations, meet increasing regulatory requirements, and modernise the aging installed base.

ARC estimates the total installed base of DCS systems worldwide to be over US$65 billion.

“The rapid growth of the DCS market, and the battle for the installed base, make it no easy task for the market leader, but ABB still retains its leading position in the worldwide market for 2006. The company continues to enjoy the largest installed base of any supplier, and is making key strides in evolving its installed base forward to its System 800xA platform,” says Larry O’Brien, Research

Director for Process Industries, ARC. “ABB is also the market share leader in key global verticals including Oil & Gas, Electric Power, Cement and Glass, and Pulp and Paper and the regional leader for Europe/Mid East/Asia (EMEA).”

Oil & Gas Leads Markets The Oil & Gas, Refining and Power industries superseded the Pharmaceutical and Food & Beverage industries as the fastest growing DCS markets in 2006, providing new areas of opportunity across all geographies. ARC forecasts that Oil & Gas will see more growth in the DCS market than any other industry area over the next five years; this growth will be driven by increasing investments in oil exploration and production.

Asian Powerhouse According to ARC, Asia is still a powerhouse and opportunities continue to abound in the Middle East, Eastern Europe, and Latin America, but the developed markets such as North America and Western Europe are beginning to show signs of sluggishness. ARC expects the current growth phase of the global market for automation to last through the next several years. While the overall market remains strong and will continue to grow, odds are that there will not be the stellar growth in the automation marketplace that was present between 2005 and 2006.

From a macroeconomic perspective, both China and India are poised for significant long-term growth. Both countries are increasing their focus on manufacturing for export, in addition to developing infrastructure, investing in basic industries, and in training personnel to operate automation plants. China is still the primary catalyst for global growth in the automation industry. As a result, ARC expects that China will be the single biggest geographical market for automation products and services in 20 years.

NI: Real-Time Multicore Support & Statechart Design Texas, US: National Instruments has released the latest version of the graphical system design platform for test, control and embedded system development. LabVIEW 8.5 extends the embedded platform to program multicore, real-time processors.

The latest version combines the familiar graphical programming environment of the software with commercial multicore hardware to achieve significant performance gains.

Additionally, LabVIEW 8.5 introduces the LabVIEW Statechart Module for higher-level designs to run on targets including FPGAs, real-time systems, PDAs, touch panels and a variety of microprocessors.

With the inherent parallel nature of the graphical code, embedded developers can enhance applications ranging from design validation systems such as hardware-in-the-loop

simulators to complex control systems such as high-speed particle accelerators. To achieve real-time symmetric multiprocessing (SMP), NI developed a realtime load balancing scheduler to automatically assign tasks to different processor cores, providing performance improvements without sacrificing determinism or requiring user code changes.

The Statechart Module gives engineers an alternative to designing systems with a high-level diagram based on the Unified Modelling Language (UML) standard. Statecharts are commonly used to design state machines that model the behavior of

real-time and embedded systems to depict event occurrences and responses for designing digital communication protocols, machine controllers and system-protection applications.

The seventh part of this series looks at the requirements of safety-related communication. By Christian Dressler

Safety-Related Communication T

ypical application fields for safetyrelated communication include: off-road vehicles, industrial machinery, cranes, medical equipment, or fire-protection doors. Devices such as emergency stop switches have to communicate in a safe way.

The residual error probability of the transmission of a CAN data frame using standard hardware is about: ρ = 4.7 x 10-11 error rate in a network consisting of 10 nodes. With every 1000th frame being erroneous, the probability calculates to ρ = 4.7 x 10-14. That means an undetected error occurs in a network under average conditions about every 2000 years.

As the details of the internal structure of microcontroller units cannot be readily verified, a different way is needed to get CAN hardware certified.

A concept has to be created, which ensures reliability of communication independently from the used hardware and its properties. One of the safety mechanisms which can be verified by standards bodies is the use of a safetyrelated protocol.

Safety-Related Protocol An appropriate protocol is fundamental for safety-related devices. Such a protocol is specified in CiA 304 for example. It is based on CANopen and considers bit errors, loss or delay of frames, wrong receiving order of frames, and un-wanted extra frames.

This is achieved by the use of SRDOs (safety-related data object), SCT (safeguard cycle time) and the SRVT 14 industrial automation asia | September 2007

time

(safety-related validation time). The protocol also provides a so-called GFC (global failsafe command). These terms are introduced as follows.

An SRDO is comparable to a PDO, with the dif-ference, that the data is sent twice: two CAN frames with different identifiers (at least two bits have to be different) are sent consecutively. They contain the same data, but the second frame stores the data bit-wise inverted.

This concept is called serial redundancy.

The receiving device verifies, if both frames of an SRDO have the same content.

SRDOs are transmitted periodically.

When SCT expires and no SRDO has been received yet, the device switches into safe state.

The SRVT defines the maximum

time, which may elapse between the both frames of an SRDO. If they are not received within SRVT the device switches to safe state.

The both timing parameters are illustrated in Figure 1.

The network can be used for both, conventional services and SRDOs at the same time by all devices. Consequently, traffic could increase and frames with lower priority may be delayed.

The GFC is used to reduce the reaction time when a device wants the other devices to go into the safe state. It is a single CAN frame with high priority and no data content. The message will be received by all means, because a GFC is always followed by an appropriate SRDO. The number of SRDOs in a network is limited to 64. www.iaasiaonline.com

Hardware Certification Four safety integrity levels (SIL) are defined, with SIL4 being the most dependable and SIL1 being the least.

Nowadays, more and more safety related applications migrate from wired connections to a serial bus system. The devices can be certified for use in functional safety applications according to IEC 61508, giving evidence that the application, including device, is compliant.

The SIL requirements for hardware safety integrity are based on a probabilistic analysis of the device.

To achieve a given SIL, the device must have less than the specified probability of dangerous failure and have greater than the specified safe failure fraction.

The international standard IEC 61508 defines SIL using requirements grouped into two broad categories: hardware safety integrity and systematic safety integrity. A device or system must meet the requirements for both categories to achieve a given SIL. To get a μC certified according to safety standards does afford more than just implementing a safety protocol.

For example, when an actor may be connected to the safety hardware, a www.iaasiaonline.com

watchdog or a similar mechanism has additionally to monitor the μC. Also, peripheral devices (eg: power supply) or programming modules, have to be monitored. A consortium formed

by CiA has developed hardware that is certified according to SIL 3, with safety-protocol pre-programmed. The structure can be seen in Figure 2.

The MCU uses two CAN controllers, which are used for redundancy reasons.

The CAN frames are received by both controllers and verified. When a CAN frame is sent, the used controllers alternate.

Using Safety Hardware Working with a safety-related node in a network does not mean that the whole network is safety-compliant. Every part of a network has to be checked for safety until the whole system is certified.

With CAN and the CANopen safety protocol it is possible to interconnect the safety-related devices in a network directly. No PLC is needed, eg: an emergency switch taking effect on a safety relay. The logical linking of devices is similar to traditional wired connections.

Coming into the final quarter of 2007, an events roundup indicates that the regional Profibus association had an activity filled first three quarters in 2007. Response from the roadshows was generally positive, attracting many industry players interested in becoming members or sponsors.

The association participated in major trade events such as IMAC in Bangkok, Thailand; OGA 2007 and Industrial Automation 2007 in Kuala Lumpur, Malaysia. Upcoming events for the remaining part of the year include the Regional Industry Networking Conference (RINC) held at the Singapore Polytechnic (November 1–2, 2007) and CIA 2007 (November 27–30, 2007).

Asset Management: Information is contained in three different files: • GSD files specify the communication between the master and slave devices • FDT/DTM is a standardised Profibus interface specification that allows the integration of intelligent devices into, for example, asset management and process control systems • EDDL is the IEC based integration of intelligent devices and information displays This workshop will go through the entire process of network configuration.

Audio Paper: Why use a fieldbus?

An audio white paper in MP3, as well as in pdf form can be downloaded from the international website. It explains the arguments for the use of the fieldbus system and associated advantages.

Workshops Workshops were also conducted in Singapore, Thailand, Malaysia and Indonesia, concurrently with some of the roadshows. The association is currently gearing up for an upcoming roadshow/workshop in Vietnam.

Foundation Celebrates 10th Anniversary

The Fieldbus Foundation celebrated its 10th anniversary in the Asia-Pacific, at the National University of Singapore Students Union (NUSSU) Guildhouse on July 19, 2007.

The event drew a large crowd of automation suppliers, endusers and leading industry figures.

Guest of honour, President and CEO, Rich Timoney delivered a keynote address describing the dream of a group of visionaries that became a reality – first, an industry-standard fieldbus technology, and then an automation infrastructure for operational excellence. He singled out the contributions of those people who helped make Foundation fieldbus the ‘technology of choice’ for process automation in Asia and around the world.

A short address was delivered by Jonas Berge, President of the Singapore marketing committee. He noted how ‘mega-projects’ in the Asia-Pacific region are increasingly adopting the technology on ever larger scales.

A fieldbus expert panel consisting of Mok Wing Kee, ExxonMobil; Leong Gim Heng, Shell; Dr Joachim Zobel, Novartis; Stephen Weng, Yokogawa; Alvin Wong, Emerson Process Management; and Rich Timoney and Hisashi Sasajima, Fieldbus Foundation, fielded questions form attendees.

For resulted. discussions interesting Several example, it became clear that to fully benefit from digital architectures, bus alone is not sufficient. The software that unleashes predictive diagnostics information must also be in place to complete the infrastructure.

In addition, the discussion gave Mr Timoney the opportunity to explain the latest developments to better support intelligent device management as per the NAMUR NE 107 recommendation. He also provided an update on the FF-SIF technology verification and the parallel development of engineering and operations best practices for safety bus.

Following the formal presentations, Mr Sasajima, VP, Asia-Pacific operations toasted the foundation’s continued success. The evening ended on a high note with food and drinks, as well as casual networking among industry associates.

End User Council The Singapore End User Council (EUC) recently met to discuss the latest progress in Foundation technology and to share fieldbus application experiences. Chung Ock Jin, Acting President of the Singapore EUC, spoke on the proliferation of intelligent devices in process automation. President and CEO, Rich Timoney, gave a presentation titled ‘Changing the Playing Field’.

Mr Timoney said that the scope the technology makes it a process automation infrastructure – one of the most advanced and scalable solutions available. It is supplierstandards-based, and neutral providing end users with a common framework to implement and manage strategies for operational excellence

and continuous improvement in process manufacturing.

Jonas Berge, Chairman of the Singapore Foundation’s Fieldbus Marketing Society, presented on the topic of ‘Keeping Fieldbus Systems Up-To-Date Communicators And Using EDDL.’ The role of EDDL in the overall scheme of things was explained. According to Mr Berge, recent enhancements to the IEC add technology EDDL 68104-3 significant value for diagnostics, setup, and calibration. They allow device manufacturers to neatly organise device information on tabs and in frames. Images illustrating wiring, block diagrams, gauges, bar graphs, and strip-charts can also be included.

The HTML-like characteristics of EDDL technology makes it desirable as a long term solution, since it is not affected by upgrades or changes in operating systems. Enhanced EDDL is also more secure and robust, since it is not executable and does not involve procedure calls between applications from different vendors.

There is much greater emphasis being placed on device management software and administration.

Seamless Data Integration:

Unlocking The Hidden Capacity Of Process Plants Much has been made of the benefits of open and interoperable fieldbuses, but not enough attention has been paid to data structures.

By David Marschall (L) and Tieng Ling (R), Senior Principal (MES) Project Execution Engineers, Emerson Process Management

I

n an ideal world, all communication and record keeping in a plant, from production floor to boardroom, would be seamless, immediate and error-free. A good start towards this end is embodied in ISA-95 (formerly known as SP95), the international standard for the integration of enterprise and control systems, although, this has not yet spread to all companies or solved all problems.

ISA-95 divides plant activities into four levels (five, if you include Level 0, the physical production equipment itself). Starting at the highest (enterprise) level, these are: • Level 4 — This is the ERP level.

It is concerned with business logistics management, including plant production scheduling, shipping, receiving, inventory and so on. The interface between Level 4 and Level 3 is handled by the business process information network. Information exchanged includes production capability information, product definition information, productions scheduling and production performance.

• Level 3 — This is the MES level. It is concerned with manufacturing 20 industrial automation asia | September 2007

•

operations management: dispatching, detailed production scheduling, production tracking and so on. Major activities at this level include maintenance operations, inventory operations, production operations, quality operations, management of documentation, management of security, management of configuration, and management of compliance. Equipment status maintained/validated by MES also includes other systems such as LIMS, WMS and CMMS. Level 3 connects to Level 2 via the operations information network.

Level 2 — This level is concerned with the actual manufacturing process, be it batch control, continuous process or discrete control, and in some ways can

•

be considered as two levels. The upper part includes equipment managed/monitored/controlled

by HMI, SCADA and batch systems, which connect via the automation networks to the equipment below it that provides operational control: PLCs, DCSs and packaged systems. Level 2 interfaces to the level below it via a number of discrete and process device communication networks.

Level 1 — This level consists of the physical interfaces between the control equipment and the physical machinery. Equipment includes I/O, actuators and sensors.

With such an orderly arrangement, and with the appropriate networks in place, one would think that information would flow smoothly from level to level. At levels 1 and 2 much of it does, or plants would not be able to operate at all, but there are still significant difficulties, particularly between levels 2 and 3, and even within level 3. Each requires information from a separate source – typically in a different form. Some information is found in databases, some in paper records. The databases tend to be disparate, and paper

ISSUES & INSIGHTS

Paperless One of the biggest steps forward would be to get away from paper.

The paper system fosters missing data, errors, inaccuracies and wasted time. Even the physical amount of paper can be a problem. A recent conference on MES issues included a presentation from a company that produces pharmaceutics based on the genetic makeup of each individual patient. The company tracks each person and the drugs made for that particular person through its manufacturing process.

The analysis has to flow

through the system as the drugs are manufactured in order to prove efficacy and comply with multiple regulations, but in doing so the company creates about 1.5 to 2 ft of paper per person per product – all of which must be managed. The company hopes to grow to the point that it processes drugs for perhaps 1000 people every two weeks. It would have to go paperless, if for no other reason than that it will not be able to buy enough warehouse space just to manage the paper.

While not every company is faced with 1.5 ft of paper per production lot, it still generates a great deal of paper involving materials management, laboratory information, training records that have to be checked or maintained, equipment logs, process control system logs and things of that nature. The systems that generate them are typically provided by different vendors because nobody really has an integrated or total solution. Any realistic solution must somehow encompass all those disparate systems or islands of automation.

One of the issues, particularly in regulated industries, is the time required for a review of paper batch records. It can exceed the manufacturing process time by two, three or more times. A 14-day manufacturing process might require two months to review the paper batch record before the product can be released. Meanwhile the product sits in a warehouse unsold while the clock on expiration starts ticking.

Paperless record keeping

Error Rate Another major problem with paper records is the error rate. It has been estimated that around 95 percent of paper records have errors of some kind before being reviewed and corrected by the manufacturing people and moving on to the quality department. We did a study in which we found that a large percentage – 60 percent or more, probably – of these errors were omissions and transpositions.

All companies have processes in

Linking databases can be a challenge

records are notoriously subject to human errors and omissions.

This is a long way from the goal of tying together process control and equipment management, and then integrating that into manufacturing operations, like recipe execution, materials management, asset management, and so on.

Linking Databases There have been attempts to link individual systems, like LIMS with batch systems, by simply doing database queries. Unfortunately this method always poses a great challenge as the individual system does not necessarily provide information like the context of a batch, and even when the link is successfully developed and working such one-off, site-specific solutions are not transportable from one company to another or even from one site to another, within the same company.

One example was a pharmaceutical plant that had built up about 250 different spreadsheets, databases and other software tools to meet their record keeping needs. As one can imagine, trying to maintain 250 different applications, connect them together and ensure that the batch record context was consistent was www.iaasiaonline.com

a major headache. It simply didn’t work.

September 2007 | industrial automation asia 21

ISSUES & INSIGHTS place to catch errors, so when the product goes out the door all of those things have been addressed, but such correction takes supervisor time and operator time – anywhere from four hours to a day or more – that could be spent better on producing output.

A right-first-time rate in the single digits is unacceptable.

If the errors cannot be corrected, or the missing data cannot be found, the product must be dumped, although no company is likely to reveal how often that happens.

Value Of Real-Time The best answer would be to have all needed data in real time, and to be able to verify things proactively using electronic work instructions that prevent human error and streamline production.

This is to avoid problems instead of reacting once they’ve happened.

An example is verification of training. Before an operator in a regulated industry can carry out a process, that person has to be trained on it; if not, then technically there is a deviation.

Yet today, because of the overhead and manual effort involved those checks are often treated as a deviation or an audit after the fact, and it is assumed that those records are maintained and that all needed training has been done. With modern paperless systems it is possible to check those in real time before the action is taken, before the activity is performed. That is seldom feasible in a paper world.

Applying the same methods to a LIMS, the automation system should take over management in real time, handling the submission of requests, tracking which ones are still outstanding, and incorporating the results into the record so that everything is available for the review process with no missing information and no missing reports.

Unlocking Hidden Capacity As an example of the timesavings possible with proper information handling, we are familiar with a 22 industrial automation asia | September 2007

company that uses a fermentation process to produce an intermediate material that is considered as internal or mini inventory and must be analysed before being used.

Currently this takes one or two weeks, but the company plans to go to zero review time. The automation process will allow the company to take the risk and do the review process after release. If there is a problem they will catch it later on, but the odds of that happening are so low that they don’t expect it to be an issue. They’re saving one to two weeks per production cycle in the manufacturing process.

As a general rule, comparing normal cycle time to best-case cycle time, consider a product that, under normal conditions, takes 120 days to go from receipt of order to delivery.

Given a sufficiently urgent rush order, that time might be cut to perhaps 35 or 40 days. By adopting paperless methods it should be possible to bring the average cycle time down close to the rush-job cycle time; in general it means at least a 50 percent improvement in release cycle time.

On the manufacturing side there may be a 15 or 20 percent reduction in work effort, simply by the reduction in the cost of quality. And similar savings occur in maintenance.

Because of the way the automation systems can track productivity or equipment utilisation it’s often possible to extend maintenance times to close to the theoretical maximum; for example, if equipment calibrations are good for one year, the ability to track and monitor makes it possible to move from the usual sixmonth or nine-month cycle to close to the one-year.

Single Source When going for such improvements it is a good idea to stick to integrated systems provided by one vendor instead of many vendors and trying to integrate them together. This will minimise the number of interfaces to maintain and the change control needed as those different solutions migrate or upgrade.

Working with different vendors requires significant time and effort to resolve conflicts, overlaps and holes.

Choosing a single source makes it possible to put all that burden on the vendor, which lowers your risk, makes it easier for you to operate, and lets you focus on the things that you care about – how your plant runs versus how well your systems talk to each other.

epperl+Fuchs is developing WirelessHART, an industrial field communication protocol, and the products will be available in mid-2008. For process automation, products ranging from simple analog isolators via remote I/O systems to complete field bus infrastructures have been designed.

These process measurement and control applications require wire connections: costly, time-consuming wiring. But this will soon change.

WirelessHART offers huge benefits, bringing high-speed connectivity to its field devices and enabling data sharing between them ‘over-the-air’, without using a 4-20mA loop. The objective is to produce a wireless communication standard for process measurement and control applications.

To bridge the distances in widespread facilities, a flat mesh network is utilised, with each device acting as a signal source and a repeater.

Information is routed through the whole network until it reaches the base station as the final recipient.

It is for setting parameters of field devices, supervising uncritical measurements and environmental values, managing and optimising assets, supporting preventive maintenance, monitoring performance, and managing energy.

These applications are a good introduction to wireless technologies since they do not demand hard requirements for latency and transmission security. Utilisating a mesh network in non-critical applications is practical.

Alarm Management:

Increasing Relevance, Improving Usability

The implementation of an effective alarm management program involves creating a comprehensive and consistent alarm philosophy for documenting, collecting and analysing alarm data. By Frost & Sullivan Christian Lagereek

O

n March 23, 2005, 1:20 pm, an explosion at the third-largest oil refinery in the United States, the BP Texas City Refinery, leaves 15 people killed and 180 injured. When a distillation tower was unknowingly overfilled, extreme pressure resulted in the release of flammable hydrocarbon which then caused the massive explosion.

Critical Lapses Several factors contributed to this disaster which resulted in a financial loss of US$1.5 billion. However, the Final Investigation Report of the incident, released in March 2007 by the US Chemical Safety and Hazard Investigation Board, highlighted lapses in alarm management that were critical: • “The tower’s high level alarm set-point was exceeded 65 times during the last 19 startups, with more than 50 hours of operating time with the high level alarm activated”.

• “The redundant high level alarm (for the distillation tower) did not activate. When the...tower was filled beyond the set points of both alarms...in the early morning 24 industrial automation asia | September 2007

•

•

•

on March 23, 2005, only one alarm was activated. The high level alarm was triggered at 3:09 am.

The redundant hardwired high level alarm never sounded”.

“The (redundant high level) alarm’s set-point was not known to operations personnel or provided in the procedure, control data, or training materials”.

“A functionality check of all alarms and instruments was also required prior to startup, but these checks were not completed”.

“Tower pressure alarm set-points were frequently exceeded, yet the procedure did not address all the reasons this might happen and the steps operators should take in response”.

Companies the world over are looking at these findings to understand not only how best to prevent such disasters from happening on their watch, but also to reassess their entire safety and risk management approach and specifically revisit their alarm management approach and practices.

Intrinsic To Safety Alarm systems have been an intrinsic part of plant safety management for a long time. They play a critical role in alerting operators to a change in operations at a process plant, inform operators about the nature of the change and guide operators to implement corrective action.

•

Poor alarm management results in: Increased downtime. This translates into lost production as well as increased operator costs through overtime, and higher lifecycle cost of equipment through increased maintenance costs Reduced plant productivity.

When operators do not read early the signs of a developing problem, their response to alarm floods (large numbers of alarms annunciated at the time of process upset) typically takes the form of stabilising the process through reducing the rate of throughput Reduced quality (when alarm systems fail to alert operators www.iaasiaonline.com

to corrective action at the right time, off-spec product has to be contended with) Reduced operator effectiveness, higher operator stress levels and increased operator staffing costs In the worst-case scenario, alarmrelated confusion can result in or aggravate serious industrial accidents Increased insurance premiums on plant equipment or fines incurred by not meeting regulatory requirements

Too Much However, despite their obvious significance, alarms have become yet another case of having ‘too much of a good thing’, making less functional what was once an effective safety and productivity improvement system.

When control systems became mainstream, they also brought down the cost of alarms; thus increasing the proliferation of such alarms. After all, engineers did not have a strong cost disincentive to configuring excessive numbers of alarms.

With this excess came reduced visibility of urgent and underlying problems, increased clutter that operators had to deal with, and longer response time to undertaking appropriate corrective action.

Systematic Approach To help organisations move away from the ad hoc approach of the past and adopt a more systematic and rational approach to alarm management, in 1999 the Engineering Equipment and Materials Users Association (EEMUA) released 191, ‘Alarm Systems: A Guide to Design, Management and Procurement’. This guide has rightly become the global reference point for alarm management. Its second edition – available from June 2007 – significantly updates and builds on the first edition.

Designers and operators have much to gain from using EEMUA 191 when undertaking improvement of their existing alarm systems or launching into a new alarm management program. www.iaasiaonline.com

The Essentials To understand how best to improve an existing alarm system or introduce a new alarm management program, it is useful to approach the task using the steps outlined in the well-known Six Sigma sequence.

Successful alarm management is based on a comprehensive and consistent alarm philosophy document that defines: • • • • • •

•

• •

Business objectives to be met Needs and requirements of the users of the alarm system Alarm system design principles Compliance parameters Roles and responsibilities Criteria for alarm generation, setting, prioritisation and presentation Management of Change (MOC) (for example, tracking authorised and unauthorised changes to alarm settings or alarm suppression or shelving) Tr a i n i n g / m a i n t e n a n c e parameters Escalation guidelines (moving from normal status mode where operators are trying to keep the process within the ‘safe envelope’ to emergency/ disaster management)

Measure Typically, with thousands of alarms per site, a ‘stock take’ of the existing process, alarms and trends is critical before any changes are implemented.

But while engineers and designers appreciate the benefits of such an

exercise, the task – by virtue of its scale – can be quite daunting.

This is where certain plant historians (central data repositories that gather, historise, archive and distribute plant data) can simplify the task. For example, CitectSCADA Reports, the plant-wide reporting solution from Citect, is capable of accurately recording all alarm data and tag values at high speed. Such a tool can help engineers and operators gather and organise alarm data from across the entire site.

Analyse If gathering data from thousands of alarms appears daunting, then analysing such data to derive useful insight can be even more formidable an undertaking.

Some plant historians provide assistance with this by helping engineers and operators with the following: • Event analysis: Pulling up all alarms that occurred at a given point in time, be they basic process alarms or aggregated alarms or even critical safetyrelated alarms.

• Alarm and event archiving: Historising all alarms and events for long term analysis.

• Alarm analysis, which includes: – Identifying consequential/source alarms around which other alarms are triggered – Identifying nuisance alarms such as stale alarms (that remain present for – extended periods of time), chattering alarms (that go in and out of alarm mode in a short span of time), or duplicate alarms (that persistently occur within a short period of time of another alarm). Pareto analysis can help rank nuisance alarms by frequency; to help detect the so-called ‘bad actors’ – Identifying shelved alarms (temporarily suppressed) or permanently suppressed alarms (that are prevented from appearing on the operator’s screen) September 2007 | industrial automation asia 25

ISSUES & INSIGHTS •

Alarm setting analysis by the state/mode of operation of the plant

The fruits of such analysis are many: Cutting through the clutter: EEMUA 191 suggests that 150 alarms per day (one every 10 min) presented to an operator is ‘very likely to be acceptable’ and 300 alarms per day (an alarm every 5 min) is considered ‘manageable’. In reality it is not unusual to record tens of thousands of alarms per operator per day, which makes such a system self-defeating.

Identifying nuisance alarms helps to eliminate unnecessary or ineffective alarms, thus bringing the number of alarms per operator to a more manageable ratio.

To do this, clear justification for each alarm is required. An alarm’s reason for being should be related to a specific problem or abnormal situation and also to a specific and defined operator response. If there is no problem or if the alarm is not intended to elicit specific operator action, then its legitimacy should be questioned. A process indicator or alert does not automatically equate to an alarm.

Under the carpet: Analysing shelved alarms can help highlight potential reductions in alarm numbers there as well. More importantly, by looking at how long important alarms have been

shelved or permanently suppressed, operator practices can be corrected (having shelved an alarm, there is no guarantee that the operator remembers to go back to reactivate it).

The heart of the matter: Identifying root alarms or consequential alarms helps ensure that in an alarm flood, prioritisation models have been configured such that the consequential alarm does not get lost or remain unnoticed.

For consequential alarm and event analysis, most historians would compare one set of alarm data with another set of alarm data (depending on the query placed). However, what is even more useful is to be able to compare alarm data with plant/

process trend data.

This is significant because alarms – being reactive in function – cannot anticipate by themselves any process drift towards an abnormality which could eventually lead to breakdown or process failure. Co-relating alarm data with trend information can help throw up such insight.

Fine-Tuning It can also help in fine-tuning alarm settings and in linking alarm spikes to specific process conditions (startups, shutdowns, change in process set points such as tank levels, pressure, temperature levels etc), changes in instrumentation or new or changed control system configurations. In addition, it is by analysing operator response to alarms (and not simply focusing only on alarm data) that poor alarm system design is identified.

CitectSCADA Reports offers such an option, since it historises both alarms and plant process trends. This way, alarm and event data can be corelated to trend data from the plant to throw up anomalies or areas for alarm rationalisation or even assist in incident reviews.

The ‘Human’ Dimension In the final analysis, successful alarm management is not about the equipment or the alarm, but about people who impact and are impacted by the alarm system – operators, process and control engineers, maintenance personnel, shift supervisors, instrument and control system technicians, designers, safety officers, training staff and senior management.

To implement a successful alarm management programme requires factor-ing in the different expectations and priorities as well as the differing levels of awareness and understanding among these diverse groups of stakeholders.

Tools that can help to effectively share alarm analytics and the resulting insight across these stakeholders in a simple, relevant, meaningful and easy-to-understand format will help ensure that alarm management is fed back to the multilevel and multi-disciplinary input it requires to validate it and keep it relevant to the business objectives and the alarm philosophy of the organisation. Tools that can take alarm KPIs and benchmark them against industry best practice, could take alarm management to the next level and provide the organisation alarm report cards that can directly result in improved productivity, profitability and safety.

Customisable downtime reporting allows production to be optimised at a cement plant. By Citect

• •

•

Maximising Cement Production

A

ustralian national cement supplier, Adelaide Brighton Cement (ABC), employs over 1,300 staff, with major sites at Birkenhead, Angaston, Cockburn Cement, Swan Cement and Independent Cement and Lime. The Angaston site has 92 employees who manage the manufacture of lime, cement and clinker.

The plant has a manufacturing capacity of 250,000 tonnes but faced restrictions in maximising its quota due to outdated technology and processes.

ABC recognised the need to upgrade its technology and improve the quality and efficiency of its manufacturing operations at Angaston.

Plant Performance In 2001, ABC adopted a management style that focused on continual process improvement for its plant and operators. This led to the development of initiatives such as Six Sigma process improvement teams, standardisation teams and operational performance managers.

The drive to continuously improve operations has helped to identify unscheduled system downtime as a significant contributor to an increase in production costs against raw material output.

The Planning and Plant Performance team gathered downtime 28 industrial automation asia | September 2007

data using a number of sources such as control room log sheets, Microsoft Access databases, Excel spreadsheets, SPC control charts and CitectSCADA reports. This information was then analysed and reported during weekly performance meetings.

Using Pareto analysis of this data, ABC was able to define the root cause of the top ten plant stoppages.

Although this information was carefully collated each week, it was always analysed some time after the event, which often delayed an immediate response.

In addition, the effort required to collect the data was in itself affecting plant performance as the process engineers could spend up to three days per month simply generating reporting data. ABC needed a more efficient method to measure, in real time, the overall equipment efficiency (OEE), taking into account the availability, quality and performance of each asset.

Requirements • ABC approached Citect to help develop a downtime reporting system that: • Is easy-to-use so that any operator could monitor downtime occurrences during any shift • Provides access to data remotely

as networked computers were not readily available in all areas of the plant Enables automatic, real-time collection of stoppage data Is able to replace the multiple downtime reporting systems with one overall system Is quick to implement from design to active utilisation

Minimising Downtime Citect implemented its customisable Ampla Downtime reporting system that measures asset utilisation, stoppage information and trend data. The system also measures Pareto data (count and duration) by shift, asset, equipment and cause so that operators have a more detailed picture of what may be causing each stoppage and how easily it can be solved. In many cases, the operator can resolve the stoppage with minimal disruption to production.

The plant operators enter their interpretation of the situation using customised pick lists, or by entering the cause, during each shift. This data is analysed by management on a daily and weekly basis to help identify trends and abnormal occurrences for prioritised action.

The entire development from design to implementation took less than two months with operators able to access the system and report data almost immediately.

Stoppage Reduction As a result of implementing the Ampla Downtime reporting system, ABC Angaston has already reported a 50 percent reduction in plant stoppages.

Kiln Three achieved a 50 percent reduction in stoppages just one month after implementation. This in turn created increased output from each asset and a decrease in cost per tonne of production.

Ampla has reduced reporting and analysis time from three days to just one hour per month allowing operators to concentrate more time on production and process improvement.

Intelligent Motor Control

Going Modular and also provide a general thermal overload protection. Control and protection philosophies were based on conventional methods.

The introduction of microprocessor technology into motor starters two decades ago was a significant development, improving the motor protection functions, monitoring and allowing digital control. Following the emergence of open fieldbus technology more than a decade ago, the intelligent motor control system (IMCS) has rapidly gained acceptance from users.

The pursuit of lower cost, higher availability, optimised maintenance and safety heralds the arrival of intelligent motor control systems. By Gunnar Zank, Regional Support Manager, ABB Low Voltage Systems

Real Time Already considered mature in certain industrial applications, an IMCS provides extended information and process data. Communication protocols like Profibus or Modbus permit serial process control application. Robustness and response time suitability make this technology reliable for real-time applications.

Intelligent motor controllers are becoming an integral part of a plant control and management system.

commissioning times, advanced information, better diagnosis and simplified troubleshooting, all leading to less downtime.

Plant managers are seeking further productivity gains through better overall plant uptime and coordination of operations and maintenance. The key in achieving this is delivery of the right information to the right people at the right time. This would not be possible without the appropriate connectivity of an IMCS. New system architecture and communication configurations are adapting to better meet this demand.

Scalable Approach The demand for higher-level information, flexible communication and data processing is different for different industries. Although with a common target of highly optimised plant operation and availability, the approach and expectation varies with the customer. Leading technologies are adopting a scalable approach. An IMCS does not need to be complicated.

Simplicity and scalability is the key www.iaasiaonline.com

factor for such requirements. The possibility to build a MCC in certain levels, packages and upgrade facilities at any stage of a project or plant life cycle is taken into consideration.

Work place safety has become a priority when considering IMCS. There is a growing demand from separating different voltages. An independent access to electrical components and cables as well and independent control and protection part allows the personnel to work in its dedicated areas safely and conveniently.

Interferences, either personally or electrically are eliminated. The power side of the IMCS is interlocked behind closed doors enabling a control technician to work on the IMCS control part in complete safety without the need to shutdown the switchboard.

Configuration Variability IMCS applications for process industries require various different system configurations to meet different customer plant operation philosophies or site-dependent de-

mands on information flow. Multiple motor starters can be accessed via a central communication unit: This approach allows simultaneous access from several control locations on different communication interfaces.

Further, certain tasks like adding motor starters for plant extension or modifying configurations are supported through higher system flexibility.

Motor starters are fully standardised modules yet allowing a flexible use through programming facilities. Complicated starter control functions, conventionally built with relays are a thing of the past. A high number of different starter types, control schemes and spare parts are no longer a headache for plant maintenance. Off the shelf starter modules, easily available and interchangeable between plant locations, withdrawable technology with inbuilt wiring reduces the time for repair.

The high level of integration in a plant operation environment and the need of access to motor controller by control system personnel, independently of the electrical part are reflected in the IMCS. Motor controllers are conveniently located outside the motor starter yet connected through inbuilt wiring technologies. To access them there is (theoretically) no need of coordination between different plant maintenance sections anymore as electrical parts remains untouched.

The integration of the IMCS into the plant asset management system allows an optimised maintenance process. Failure analysis, maintenance trigger and spare part handling are the keys to higher operational performance of the plant. Maintenance data of the IMCS and motor are helping to optimise maintenance allowing optimal plant up time.

Reliability The IMCS monitors at any point of time the correct location of every motor controller and its starter module. It also ensures that the correct control September 2007 | industrial automation asia 31

and protection function is applied.

Mixing modules or inserting wrong type of modules does not lead to mal operation of motors anymore.

Communication integrity with predictable behaviour in case of a failure is mandatory to ensure motor availability under different circumstances.

The operational safety of a motor is ensured against breakdown in communication through continuous monitoring of the communication integrity from the motor starter to the process control system (DCS: Distributed Control System) at all times. And, should communication break down, the motor is led to a pre-defined safe state.

Furthermore, the possibility of control access from a different location is safeguarded by a user access rights mechanism. At any point of time it is clear which location can or even has operated a motor.

Communication Capabilities A standard fieldbus does not exist today; adoption varies between customers and control systems.

Preference is given to Modbus and Profibus with the emergence of Ethernet-based Modbus TCP and Profinet.

32 industrial automation asia | September 2007

Besides serving as a fieldbus communication interface to process control systems, the IMCS provides far more data than needed in a process controller. Delivering that information to the right location faces limitations imposed by fieldbus capabilities and a huge engineering effort of the DCS. Advanced IMCS eliminates such situations by providing multiple data access through central communication units or a data concentrator.

Minimises Effort The use of standard fieldbus communication is reduced to basic functions to transfer process control related data, minimising the engineering effort to its base.

Advanced information is available through Ethernet based interfaces.

Today it is all about information flow to the right operator at the right time.

OPC is a standardised way of handling additional information that is not mission critical, but nevertheless important for successful plant operation and asset maintenance.

Using OPC, customers can connect to operator stations, maintenance systems and other applications, directly without having to program a process controller. By using OPC Servers provided within the scope of IMCS, additional information for operators can be added to the faceplates without further engineering and configuration effort in both the DCS and the IMCS. Alarm and event handling is totally automated so operator stations obtain motor relevant alarms and timetagged events directly from the motor controller. The maintenance relevant information can be taken directly via OPC to the electrical maintenance system or SCADA package. With this approach the information required can be presented as and where it is needed.

Serving Up OPC OPC offers a standard interface for accessing device data.

By Marius Wotschik (L) and Nadine Haid (R), INAT

A

utomation technology produces large amounts of data. These are usually physical variables such as temperature, current, pressure or other production data such as number of units, time of error, number of errors, and so on. They are supplied by a wide variety of different devices such as controllers, level measuring devices, weighing machines, scanners, and so on.

Information is required for a wide variety of different software applications.

Certain information may be stored in databases while other data may be needed for a table calculation or by visualisation software. Information from devices supplied by different manufacturers must be provided to different applications from various vendors.

34 industrial automation asia | September 2007

In earlier years – up until 1996, before OPC, that is – a special driver had to be written for every application to which the I/O device was to be connected. There was one driver for Controller X for the link to software application A, one driver for the link to application B, one driver for the link to application C, and so on. Data had to be supplied several times by the same source – once at the request of application A, once at the request of application B, once at the request of application C, and so on. And naturally the same applied to controller Y. One driver for each application was also required here. In addition the number of drivers kept increasing with the different communication protocols and bus systems.

The arrival of OPC changed this. OPC DA (Data www.iaasiaonline.com

SOFTWARE & NETWORKS

Application B eg: spreadsheet

Process data acquisition without OPC

Access) interface offers a uniform solution with which different software applications can access a wide variety of data sources. Today’s hardware manufacturers now only develop one single driver – the OPC server. Software manufacturers on the other side supply only one OPC client interface.

As is usually the case with client-server architectures, the client utilises the services of the server. The OPC server accesses the process data of the hardware and makes these data available. OPC clients can read these ‘served up’ data or write commands to the server. The server then passes the control data along to the hardware. Thanks to OPC, only one driver – the OPC server – is now required per device. All applications – the OPC clients – access these servers. Automation without OPC is unthinkable today. The OPC interface is supported by almost all SCADA, visualisation, and process control systems.

How Does OPC DA Work?

OPC is based on DCOM/COM. The component-object model is an object-based programming model developed

by Microsoft. Software is divided into smaller, independent units – the objects (components). An object can execute certain actions (ie: supply certain methods). While the available methods are visible from the outside, the inner life of the object remains hidden. For this reason objects are enclosed and one or more interface(s) are defined for the outside. The interface contains the description of which functions are available and how these are to be used. The functions are called with the help of so-called virtual function tables (VTBL). These tables consist of a number of pointers which point to different functions.

Standard Interface OPC simplifies the link to applications by providing a standard interface which is not dependent on individual applications. This allows the customer to choose freely between products of different software and hardware vendors. Both OPC servers and clients are COM objects.

It makes no difference who developed these objects, when they were developed, or in what programming www.iaasiaonline.com

Application A eg: visualisation

Application C eg: database

language and on what Windows operating system they were written. As COM objects they can all communicate with each another.

Network capability was added to COM with DCOM (Distributed COM). In other words not only the services of the OPC servers on the same computer are available but also those of all servers which can be accessed within the network. And the client does not even notice whether the server is a local server or a remote server.

Application A eg: visualisation

SOFTWARE & NETWORKS access to the different controllers.

Process visualisation is used to dynamically represent data which are supplied – whether in the form of text or graphics. This gives users an overview of their processes together with the opportunity to intervene via buttons or touchscreens. It must also be said that not all tasks require costly visualisation.

The pointer or object-oriented approach of COM offers users capabilities which far exceed the ‘simple’ connection of finished OPC servers and clients. COM objects can be implemented in a wide variety of different applications. It is possible to program a separate client which utilises the methods of an existing OPC server provided that the programming language is object or pointer-oriented (eg: C, C++, Delphi, .Net or VB6). The OPC client accesses the server via its interface. There are two types: the custom interface and the automation interface. While function-oriented languages such as C++ use the custom interface, communication with the automation interface can be effected using script languages such as Visual Basic.

Ease Of Customisation The advantage of client programming is that it allows the application to be customised to specific requirements. INAT has handled numerous implementations in this connection.

For example, a recipe editor was developed for a customer so that recipes can be written to or read from the PLC just by pressing a button.

Recipes are collections of process parameter values such as, for example, temperature, pressure, etc.

A recipe usually forms the basis for a certain product or product type to be manufactured. The recipes are located in a database. Hardware (PLC) to be addressed is selected from a pulldown menu while data transmission can be initiated with a button. The program which is currently being executed can be called, indicated and stored in the database at all times.

36 industrial automation asia | September 2007

Sending & Receiving Since the recipe editor must communicate with controllers of different manufacturers, an all-in-one OPC server is required. For example, the INAT OPC server can handle all the primary Ethernet-based industrial protocols – it can be used for a wide variety of different systems. In addition to the Siemens protocols S7 and S5 via TCP/IP and H1 it can handle the Modbus on TCP protocol which is used to communicate with the Ethernet interfaces of Beckhoff, Phoenix Contact, Schneider Electric, Wago, and so on.

Send/receive communication can be used to transmit data to devices which do not support any of the protocols mentioned.

Not only can the recipes be read from the controller to a database, when necessary the reverse is also possible – for a product change, for instance. Data transmission is started with a button and the recipe is loaded to the controller. A test bit is also scanned prior to the data transmission.

Depending on whether this bit is set or not, the data transmission is allowed or prohibited.

Up till now, recipe parameters had to be explicitly transferred as part of a recipe data block using a programmer, for example. The recipe editor has now eliminated the need for this complicated transfer at the controller level. The transfer is handled by OPC

and the controller is free to concentrate on data processing.

Object Oriented Programming Programming an OPC client is easier than most would believe. That raises the question of whether an expensive client is actually needed for a specific application. Why not use Microsoft Excel as an OPC client? VBA, the object-oriented programming language for MS Office applications, makes it possible. Excel offers many excellent ways to present information: columns, bars, lines, circles, networks, tracking diagrams and more, depict the interrelationships and trends particularly clearly.

Numerous control elements are also available. And if that is not enough, graphics can also be imported.

With its comprehensive calculating capabilities, Excel is especially suitable for open loop and closed loop control. Almost any formulabased link can be implemented.

Numerous possibilities are available: Cyclic data acquisition, reports, data analyses, trends and so forth.

A decisive advantage is that almost everyone can be familiar with the program. From service personnel to sales engineers to management – most people already know how to use Excel and don’t have to learn a new tool first.

magine a physical world that is invisibly interwoven with sensors, actuators, and computational elements, embedded in everyday objects of our lives, and connected through a continuous wired or unwired network. Smart environments represent the next evolutionary development step in building, utilities, industrial, home, shipboard, medical, and transportation systems automation. In these environments, wireless sensor networks (WSN) have played a key role in sensing, collecting, and disseminating information about environmental phenomena.

WSN generally consist of a data acquisition network and a data distribution network (which may be the same), monitored and controlled by a management centre (Figure 1). The plethora of available technologies makes even the selection of components difďŹ cult, let alone the design of a consistent, reliable, robust overall system. The study of wireless sensor networks is challenging in that it requires an enormous breadth of knowledge from an enormous variety of disciplines.

Wireless Sensor Model A wireless sensing unit consists of four main components; namely a sensing unit, a processing unit, a transceiver unit and a power unit (Figure 2). The sensing unit consists of a sensor and an analogue to digital converter (ADC). The digital signal from the ADC is sent to the processing 38 industrial automation asia | September 2007

The transceiver connects the sensor node to the network. The power unit is the most important unit in the sensor node. If the sensor node is used in a small environment, replaceable batteries can be used. But

There are cases where nodes are attached to mobile platforms. The mobiliser unit connects the sensor nodes to the mobile platform.

There are different design constraints that have to be taken care of while designing a wireless sensor.

These constraints are fault tolerance, scalability, production costs, hardware constraints, topology, transmission media, environment and power consumption. To make matters even worse, all these factors have to be designed for a matchbox size sensor unit.

Architecture & Topologies Protocol architecture for WSN has to be designed carefully. Different applications require different protocols.

The commonly used WSN protocol architecture is loosely based on the 7layer Open Systems Interconnections (OSI) model developed by ISO in 1977.

In this model, a networking system is divided into layers. Within each layer, one or more entities implement its functionality.

Each entity interacts directly only with the layer immediately beneath it, and provides facilities for use by the layer above it. Protocols enable an entity in one host to interact with a corresponding entity at the same layer in a remote host. The OSI model is shown in Figure 3.

The OSI model has seven layers, namely, the Physical layer, the Data Link layer, the Network layer, the Transport layer, the Session layer,

the not

DLL & MAC Layers In addition to these layers, WSN has three more layers namely the task management layer, the mobility management layer and the power management layer. In WSN, the Medium Access Control (MAC) layer lies above the Physical Layer.

According to the OSI model, it is the part of Data Link layer (DLL), but in the case of WSN, there is a separation between DLL and MAC. Topologies remain an important part of network design theory. A communication network is composed of nodes, each of which has computing power and can transmit and receive messages over communication links, wireless or cabled. The basic network topologies are shown in Figure 4 and include fully connected, mesh, star, ring, tree, bus. A single network may consist of several interconnected subnets of different topologies.

In October 2003, IEEE finalised the IEEE 802.15.4 standard for WSN. This standard covers the physical layer and MAC layer (topologies) for low rate wireless personal area network (WPAN). The ZigBee standard (December 2004) provides low cost and low power connectivity for equipment that needs battery life as long as several months to several years but does not require

data transfer rates as high as those enabled by Bluetooth. In addition, ZigBee can be implemented in larger mesh networks.

Energy Conservation Over the years, sensors have gone from macro scale to micro scale and the most substantial challenge for WSN designers is the need of significant reduction in energy consumption. Small-sized wireless sensor units imply smaller power supplies which means shorter lifetime for application usage. Most of the wireless sensors these days are event driven. Even for event driven applications, energy consumed during sensing, transmission and reception of data is quite high.

Energy inefficiency in WSN is observed in sensor electronics, transceiver electronics, network protocol, network topology and programming methods. An energy aware design methodology emphasises on appropriate scalability of energy consumption which stresses on factors such as available resources, event frequencies and the quality of service.

Scalable Consumption The framework for an energy efficient WSN design highlights the collaboration between software for sensor programming and hardware with scalable energy consumption.

The best way for achieving energy efficiency is by using low duty September 2007 | industrial automation asia 39

SOFTWARE & NETWORKS cycle protocols and event driven programming. Also, the use of multihop topology over single hop in certain applications has helped achieve energy efficiency.

Current research also focuses on designing small MEMS (microelectromechanical systems) RF components for transceivers, including capacitors, inductors, etc (Figure 5). The limiting factor now is in fabricating micro-sized inductors. Another thrust is in designing MEMS power generators using technologies including solar, vibration (electromagnetic and electrostatic), thermal, etc.

Spatial Relationships Wireless sensors are coupled to the actual physical environment; hence their spatial relationship to other objects in the environment is very important. Localisation refers to the collection of techniques and mechanisms that measure these spatial relationships. A sensor data with its spatial information increases the network capability substantially.

Most of the networks are static by nature, and hence it becomes difficult to find the location of the nodes in such situations.

One method of localisation is recording the location while installing the network, which is not feasible in applications involving random deployment. There are many factors that affect localisation of nodes such as energy constraints and node limitations. Also, the environment plays an important role; for example, GPS does not work indoors while RSSI based localisation are prone to distortion due to fading.

Self-Organisation Relative localisation requires internode communications, and a TDMA message header frame that has both communications and localisation fields is shown in Figure 6. There are various means for a node to measure distance to its neighbours, mostly based on RF time-of-flight information.

In air, the propagation speed is known, so time differences can 40 industrial automation asia | September 2007

and communication between these processes. In WSN, sensors send data only when an event is triggered.

Such events occur at a low rate than other wireless systems. Hence, the programming used in wireless systems when applied to WSN, would cause considerable power consumption.

Figure 9 shows the architecture for event-based programming.

Intelligent interfaces Many software products are available to provide advanced DSP, intelligent user interfaces, decision assistance, and alarm functions. Among the most popular, powerful, and easy to use is National Instruments LabVIEW. What makes LabVIEW good for WSN? Itâ&#x20AC;&#x2122;s because LabVIEW has a unique style called data controlled execution, not sequential execution as in most of the other programs.

It has built-in drivers for many applications. It is easy to interface a sensor to a program developed in LabVIEW. Figure 10 shows a LabVIEW user interface for monitoring machinery conditions over the Internet for automated maintenance scheduling functions. Included are displays of sensor signals that can be selected and tailored by the user. The user can prescribe bands of normal operation, excursions outside of which generate alarms of various sorts and severity.

Identification Tracking

racking assets has received considerable interest in the recent years, thanks in part to Wal-Mart’s Radio Frequency Identification (RFID) inventory tracking programme. This interest has resulted in the development and improvement of various tracking technologies which can be used for different applications. In the process industries, companies need solutions that can help track critical assets and also locate personnel during emergency situations.

The geo-location of an asset becomes a new variable that can be used to reduce operating costs, and improve safety and emergency response time. Honeywell Instant Location System (HILS) seamlessly integrates best-in class location and identification technologies to meet process industry requirements and track physical objects.

Today the geo-location technology is mainly used within the supply management chain. In the process industry, these technologies can be used also for warehouse management as well as improving safety and work processes.

UWB positioning infrastructure is composed of multi-year batterypowered tags and 24 VDC-powered receivers.

The active RFID tags emit pulsed signals at high frequencies that are captured by UWB receivers. A minimum of three receivers is required to provide an accurate location of an asset (up to one-foot accuracy) using triangulation principles.

The system can also provide proximity data if less than three receivers are available. The detection range can reach up to 200 meters (650 feet) line of sight in an outdoor environment. UWB technology can also provide two- and three-dimensional geo-location information.

Wi-Fi: Wi-Fi positioning system is the best solution for applications that require approximate location information in outdoor and indoor environments. Wi-Fi positioning infrastructure is composed of batterypowered tags and off-the-shelf Wi-Fi access points. The solution is best for facilities with an existing Wi-Fi network.

Wi-Fi detection range can reach up to 200 m line of sight in an outdoor environment and 60 m in an indoor environment. The Wi-Fi signals emitted by the tags are captured by the Wi-Fi access points. Using triangulation principles, the system calculates the position of the assets.

Wi-Fi positioning system provides up to 15 feet detection accuracy which is less than UWB and works best in a non multi-path environment.

Active RFID: Active RFID systems are composed of active RFID tags emitting signals at various frequencies. The emitted signals are received by active RFID readers which will provide proximity location information. Active RFID systems have limited detection range of 35 m line of sight. The main advantage of the active RFID is cost. The active RFID tags and readers are less expensive than UWB and Wi-Fi receivers and have multi-year battery life. www.iaasiaonline.com

Global Positioning System: Global Positioning Systems (GPS) have been available for many years. The advantage of GPS is that it does not require any infrastructure. The system consists of GPS receivers that calculate their positions by measuring the distance between themselves and three or more GPS satellites.

Measuring the time delay between transmission and reception of each GPS radio signal gives the distance to each satellite since the signal travels at a known speed. The signals also carry information about the satellites’ location. By determining the position of, and distance to at least three satellites, the receiver can compute its position using trilateration. GPS devices have a short battery life (few hours) and are expensive for tracking hundreds or thousands of assets. GPS accuracy varies from 3-5 m.

ompressed air is second only to electricity in importance as an industrial energy source, and there is hardly a factory that functions without it. For many industrial applications pneumatics is the preferred drive technology, thanks to advantages such as overload resistance, long life, economy, ease of assembly, reliability, and safety.

Because pneumatic equipment generally operates trouble-free, users tend to take it for granted and typically do not look for problems or inefficiencies. This may be why air leaks are often not taken seriously. After all, wasting compressed air is usually harmless to the environment.

The uncomfortable truth is compressed air is the most expensive energy available in production 44 industrial automation asia | September 2007

facilities. Therefore, it makes sense to pay attention to the proper use of compressed air. One technique gaining ground is to monitor air consumption, as it is a good indicator of the health of pneumatic systems.

System Monitoring A common way to prevent waste is to regularly search for compressed-air leaks. Formal leak-detection programs usually involve complete, manual inspections of all airlines several times per year. Regular inspections find new leaks and also confirm that tagged leaks from past inspections have been repaired. Technicians typically diagnose pneumatic leaks by listening for hissing air, periodically inspecting tubes, and tightening fittings.

One disadvantage of leakdetection programs is that depending on inspection frequency, leaks can go undetected for a long time.

Also, inspections are usually time consuming and may be problematic in noisy industrial environments.

Inspectors often miss small leaks, which prevent repairs in the early stages before leakage becomes a major problem.

Many experts now recommend installing a network of flow sensors to continuously track compressedair use. It is more efficient and cost effective than manual inspections and detects costly increases in air consumption caused by malfunctions and leaks.

Modern Sensors Flow sensors, properly sized and installed at important locations within an air-distribution system, highlight deviations, send messages, and activate alarms when flow exceeds

tolerance thresholds. Technicians can easily pinpoint leaks, failures, and other problems, and take immediate action to fix them. In addition, flow sensors in production facilities can track air consumption of pneumatic systems – even down to specific components – and help calculate true operating costs.

Advances in sensor technology have only recently made all this possible. Until now, most flow sensors only provided real-time flow data over a relatively narrow operating range. There were also a lot of restrictions on where they could be installed. Flow measurement is, unlike pressure measurement, rather

nemometer flow sensors contain a heating element held at a constant temperature in the fluid medium. Gas or liquid flow cools the heating element due to convective heat loss, but a regulator keeps heater temperature constant. When there is heat loss, the device requires more power to hold the heating-element temperature constant. Thus, power consumption is a useful indicator of fluid velocity.

complex. Normally, sensors are quite sensitive to upstream flow conditions, so installation plays a critical role in measurement accuracy. Units often had to be located in laminarflow regions – for instance, away from tees and elbows – and this made widespread use on industrial equipment impractical.

In contrast, newer sensors contain features such as special inlet tubes or filter cartridges that stabilise flow.

Thus, users do not face installation restrictions or require specific knowledge about the incoming flow.

And a bypass-measurement system gives accurate readings over a wider flow range than was previously

The cross section of a Festo MS6 flow sensor shows the sensing element is housed away from the main flow channel.

The latest flow sensors do not place the anemometer in the main flow channel but, rather, in a bypass channel within the housing. The main channel is shaped to create a Venturi effect that generates a pressure differential and forces a well-defined proportion of flow through the bypass. This helps protect the sensor element and ensure long, trouble-free life. Readings are independent of pressure, which makes this technique ideal for a variety of tasks – even measuring rather small flows. Thus, anemometry-type flow sensors are suited for many different applications, from measuring air consumption on a single pneumatic drive to monitoring large production areas.

INSTRUMENTATION & MEASUREMENT possible. The sensors quickly install most anywhere and even temporary setups are now practical.

System Setup Flow sensors can be used throughout an entire air system, though the number of sensors and exact location depend on customer requirements. Typically, some sensors should be integrated at important points of the air-distribution system. These monitor flow to groups of machines. Any increase in air consumption would at least indicate a problem exists and note the general area of concern.

Other users are more interested in monitoring flow to a single machine or individual subsystem. In these cases, sensors quickly narrow the source of any increase in air consumption.

Finally, a single actuator is sometimes crucial to the manufacturing process or operating an entire assembly line. In such cases, it

or controller. And while currently hardwired, wireless data transmission can be expected within the next few years. Determining acceptable deviations in normal operations and where to set alarm thresholds strongly depends on the application and the user’s experience. But customerselected thresholds are not only for alarms. Trigger signals are often used to start and control manufacturing processes. And on retrofits, feedback signals can lead to higher machine speeds. Sensor data can also be used in predictive-maintenance programs.

Early recognition of an increase in air consumption is a useful indicator that repairs are needed or equipment must be replaced.

Some manufacturers have started to mount flow sensors at critical locations within their plants and display the data on a central terminal in the maintenance department.

For example, one OEM displays air consumption in different plant sections and highlights areas of higher air consumption in red. Armed with this knowledge, the maintenance staff quickly responds when and where it is needed.

and orifices.

As an example, an automotive supplier needs compressed air to clean a crankshaft borehole and possibly use airflow to also gage hole size. The goal is to ensure the crankshaft borehole diameter d = 4 ± 0.3 mm. Selecting pressure is the first step. A one-bar pressure differential is a good compromise between ensuring sufficient flow to clean the hole and, at the same time, minimising air consumption.

This results in the following C values based on the above equation: C = 147.8 lpm at d = 4.0 mm C = 170.8 lpm at d = 4.3 mm C = 126.5 lpm at d = 3.7 mm Results show significant differences in airflow, so the manufacturer can use flow sensors to determine borehole diameter and monitor consumption.

In this example, an appropriate sensor should have a measuring range up to about 200 lpm.

Continuously evaluating airflow and consumption provides useful diagnostic information and helps determine whether a pneumatic system or subsystem operates efficiently. Flow sensors can highlight problem areas and quickly detect malfunctions. Users who want to reduce production costs and system downtime should consider using flow sensors as an efficient and inexpensive diagnostic tool. They are a much better alternative than a futile search for leaks or adding compressors.

ompanie s have traditionally concentrated on the inputs and outputs of the supply network processes, with little concern for its internal management, and workings of individual components.

However, organisations today increasingly find that they must rely on effective supply chains, or networks, to successfully compete in the global market and networked economy. The purpose of supply chain management is to improve trust and collaboration among supply chain partners, thus improving inventory visibility and

velocity. The choice of technologies for internal management controls is now able to impact a company’s supply chain efficiency and performance.

A major component of inventory visibility lies in a well-organised warehouse, with an up-to-date warehouse management system (WMS) in place.

Warehouse management systems provide the backbone that runs the overall distribution operation. It organises work and aligns resources and labour to satisfy customer requirements, and optimises fulfil-

ment and distribution processes to ensure that products are delivered on time and to order. The WMS manages the order processing, receiving, putaway, and shipping functions through a cohesive integrated methodology.

However, the WMS does not optimise and direct material flow in conveying/sorting operations, determine the ideal location to store an item within an automated storage system, nor does it manage the precise details of light- and voicedirected order fulfilment.

The WCS optimises the control and performance of an automated system by maximising material flow, executing efficient storage strategies, and providing accuracy in order fulfilment and sorting.

A typical WCS would have a host interface for communication between the WCS and WMS, MES, or ERP software, as well as several standard modules, including order fulfilment, material flow and storage, sortation management, visualisation control and information management.

Peak Performance An example of high per for mance results from implementing a WMS/ WCS can be seen in Gruppo Coin’s automated warehouse management and control system.

an operator interface (MMI) and diagnostic tool for such occurrences as trolley jams.

The WMCS system is based around an overhead conveyor system supplied by Moving ITS, which provides the speed, flexibility and versatility to move trolleys freely and silently around the four-storey warehouse. The Trolley Guidance Supervisory Control System is based upon IDC’s intelligent bar code readers, which are fitted at trolley divert points to control the route of each trolley. Readers recognise and react to each of the 13,000 trolleys in the warehouse, communicating data and instructions via a gateway PLC to the RAID Level 5 Server, running on a Windows NT software platform.

This communicates to the warehouse management system via a TCP/ IP network, enabling route selection of each trolley to be designated and the monitoring of goods in real time. To ensure response times for messaging between the WMS, WCS and the PLC network are independent of server database size, an Oracle 8 relational database software is employed.

In addition to its role in passing routing instructions to the readers and confirming trolley arrivals, IDC’s server also controls the flow of empty trolleys to ensure that they are returned to a buffer; and provides

In relation to WMS, several technologies serve as key enablers.

The first is the use of radio frequency identification (RFID). The method most commonly used stores data that identifies an object on a microchip attached to an antenna (an RFID tag). The antenna transmits the identification information to a reader, which converts the radio waves reflected back from the RFID tag into digital information passed on to computers that can make use of it.

RFID technology automates the process of moving goods from the manufacturer, to a warehouse, to a store and finally to the home or business. An RFID reader captures the tagged goods’ information when loaded onto a staging area and communicates the details immediately to the backend system. It can be customised to trigger warehouse

The growing popularity of RFID has even seen a push towards regional harmonisation of band frequency at the Asia Pacific level. Singapore has rallied ASEAN to agree in-principle to harmonise RFID spectrum allocations in the 860 MHz to 960 MHz range.

Such interoperability of RFID would allow cross-border tracking of the movement of goods, similar in concept to the Boeing tests, but one level higher.

Voice Activated Another component in the modern s up pl y c ha i n i s vo ice - ac t i v a te d technology. The key feature of voice technology is the user interface. It is based upon speech synthesis and recognition and operates through a voice terminal, worn by the user on a belt, which communicates with a host control system, typically a warehouse management system (WMS), via radio frequency (RF) links.

Voice activated technology is gaining greater prominence in the warehousing industry. It is seen by some as the source of a new generation of operational improvements in the warehouse, especially for activities like picking.

The benefits of voice-directed warehousing management are threefold.

Firstly, productivity improves through significantly reducing the worksteps required for the picking process.

Instructions can be issued and validation checks carried out whilst the user continues to pick. This time saving translates into considerable improvements in productivity over the course of a shift, unlike manual picking,

which requires picking up a handheld terminal, reading the instruction from the screen, possibly pressing a few keys and then scanning a bar code. It also reduces the number of trips the picker makes to the warehouse office to get the next pick list to work on. The administrative task of confirming a picked list back to the host system can also be eliminated.

Secondly, there is greater accuracy in the ‘hands free, eyes free’ operation that is inherent in speech-controlled picking systems. It allows the realtime validation of the operation as it proceeds. Any errors in product picking can be detected and corrected immediately at this stage before proceeding. Lastly, there are indirect benefits such as ease of use by operators, fewer product damage and less physical strain, all attributable to the ‘hands-free, eyes-free’ ergonomics of voice-activated technology.

Mature & Robust Its robustness and maturity has been proven in numerous installations a r o und t he wor ld. For e x a mple Dematic, has over 80 pick-by-voice installations worldwide. The largest pick-by-voice system delivered by Dematic in Europe with 960 order pickers in one warehouse is in used in a Finnish retail chain.

As supply chains have become much more fragmented and global, companies will have a harder time putting together the right process controls and visibility in place. This is true not only from a supply and logistics visibility standpoint, but also a security standpoint to make sure nothing dangerous is slipped into a container.

It is also good for consumer confidence, to make sure the correct raw materials are being used in products – to prevent a supply chain disruption, which recently happened with the recent toy recall

by Fisher-Price. Thus, technological solutions will be increasingly sought, not just by companies manufacturing products, also by services that provide them.

Integrating demand response in control strategies allows users to leverage on both the demand and supply side of the equation. By Peter KellyDetwiler, Senior Director, Constellation NewEnergy ation

Demand

Demand & Supply Systems integrators who are able to combine a demand response programme are well positioned to help customers leverage both the demand and the supply side of the equation.

Load management and energy efficiency strategies are most effective when all elements of the energy chain are linked together for the customer. Integrating a LON based system, ideally with LonMark certified products, makes this possible.

Systems integrators who are able to bring the supply and demand side expertise to the table have a competitive edge when assisting end users with managing energy in their facility. This expertise can be brought to bear in three primary ways:

Response

n today’s business environment, companies are thinking about energy as a strategic asset that is important to every aspect of their business. The scenario is all too familiar. CEOs are under pressure from shareholders and board members to green-up and cut greenhouse gas emissions, reduce energy consumption, and shrink their carbon footprint.

CFOs are looking for increasingly more creative ways to trim costs and gain a return on investments, and facilities managers are tasked with the challenge of keeping a wide range of systems operating efficiently and effectively under a myriad of conditions, including a volatile energy market and a steady increase in capacity costs. Is the decision to fire up the generators the right one when ISO calls for a curtailment on the hottest, or coldest, day of the year or is there a more sophisticated approach for today’s fiscally and environmentally minded CEO? One Platform LON systems integrators already utilise one comprehensive platform to manage the lighting, HVAC and building systems within a facility. Integrating demand response into this platform brings the supply side of the picture into perspective, further leveraging their customers’ ability to control the internal environment not only with regards to creature comfort, but also energy consumption.

The result is a smarter and more energy responsive building that is positioned to react flexibly to curtailment 50 industrial automation asia | September 2007

IN BUSINESS

Real-Time Savings Further savings can be realised from access to meter and price information systems, which allow up-to-theminute views of energy usage and costs and the ability to employ this information to better shape and control usage patterns. Real-time energy information and the ability to shape energy load will put a business in the driver’s seat when responding to a demand for curtailment from the ISO and when navigating a volatile energy market.

Demand response can be integrated into energy efficiency upgrades to older, existing facilities or incorporated into the design and construction of new buildings. This successful bridging of energy supply with actual on-site demand addresses everyone’s needs from the corner office to the control room. For example, Constellation NewEnergy has worked with New York’s Syracuse University since 1995 on multiple projects involving more than 40 buildings.

Energy Management Among the upgrades is a new energy management system which controls all HVAC systems using the LON platform in 44 buildings. VAV conversions were made in more than 12 buildings, including more than 185 lab fume hoods and VSDs placed on more than 50 individual pumping and air-handling systems ranging in size from 7.5-100 Hp. Constellation NewEnergy worked with the incumbent systems integrators to help design and install the controls upgrades.

The investment has resulted in annual cost savings of US$1.9 million and reduced energy costs by more than 10 percent over a five-year period. New electric metering, measuring and monitoring systems provide necessary information for the university to comprehensively evaluate, assess and shape its energy load going forward.

The Benefits Demand response provides measurable benefits to customers that go well beyond the financial. Among these are contributing to the effort to prevent regional blackouts without resorting to on-site generation.

While other demand response providers typically use generators as their main load reduction product, leading companies believe in leveraging building automation systems and applying advanced control strategies for true load shaping. This method helps to prevent brownouts, rolling blackouts and high cost peaking plants from coming online during ISO emergency curtailment events, thus a demand response programme is more akin to a “virtual” peaking plant. www.iaasiaonline.com

Enhancing the elasticity of a company’s facilities is fundamental to reducing energy needs in the future

Quantum Automation

Enhancing the elasticity of a company’s facilities is fundamental to reducing energy needs in the future and taking unnecessary stress off the grid during peak demand.

There are a multitude of opportunities to leverage on – lighting, primary air handling and pumping equipment, central plant operations and HVAC systems.

Shaving Off Energy Shaving off-peak usage results in additional kilowatts becoming available where they are most needed on the grid without the need to fire up older gas, oil or coal plants to meet regional demand.

This puts companies in a position to contribute to the larger effort of preventing regional blackouts, without resorting to on-site generation and the associated issues of run-time and air emissions that accompany them.

During demand response events, customers who are set up with the technology and metering applications to curtail at least 100 kilowatts of electricity consumption during peak demand hours are able to reap year-round financial benefits.

The result is a reduction in energy costs through regular monthly payments for committing to participation in the ISO curtailment program as well as the savings earned during actual curtailment events. And finally, integrating demand response into existing platforms positions customers to fully take advantage of an ever evolving and increasingly more sophisticated energy market.
