he Industrial Internet of Things (IIoT) has developed into a key means to help realize the smart factory and intelligent manufacturing concurrent with development of the internet of everything. Control Engineering China asked National Instruments (NI) Corp. China executives, Cui Peng, marketing manager, and Yi Xilu, technical market engineer of Internet of Things (IoT), how to accelerate IIoT implementations.
IIoT platform architecture
Collection and analysis of Big Data runs through IIoT processes, from front-end data acquisition, transmission, transfer to the cloud, and to a decision-making terminal. Data acquisition and analysis are core to NI offerings, an advantage for those seeking an IIoT platform architecture. “As for IIoT, we will help customers build a basic architecture, emancipate them from data acquisition, and allow greater focus on data analysis,” said Peng. “In the past, the customers spent 80% of their time to carry out the front-end system architecture and data acquisition, with 20% left for data analysis.” A platform of hardware and software can help customers to speed up IIoT deployment, Peng suggested. Elements to help with IIoT deployment include embedded industrial controllers, systems on modules, machine vision, motion control, industrial touch screens, data acquisition and control platforms, and cloud-based data management and analysis software. Xilu added, “The basic architecture of IIoT as produced by NI can realize the intelligent test and protocol test, as well as monitor equipment in the industrial field. In such cases, early design verification and later mass production will be monitored online in real time to enable predictive maintenance, protect stable operation of assets, help customers enhance production efficiency, and shorten the production period.” As IIoT develops into a comprehensive systemic engineering architecture, a cooperative ecosystem helps. Companies that offer open-ended platforms of integrated hardware and software also help. Peng said, “Another extension of the NI platform concept lies in the industry development, jointly promoted by cooperative partners under the assistance of the ecosphere. Generally, we will provide a platform offering to satisfy customer-defined demands.” To supply customer solutions, Peng continued, “We will adopt two methods. First, we will join with local or

global professional partners to build the solution suitable for the specific field. Second, we cooperate with end customers to develop the specified system.” In the U.S., NI joined with Cisco, Intel, and other industrial companies to build an IIoT Lab at NI’s Austin headquarters, focusing on the micro-grid control and communications, advanced manufacturing control, heavy equipment asset monitoring, and other fields. NI also is among companies working on and promoting the IEEE Time-Sensitive Networking (TSN) standard. IIoT Lab members are producing TSN-based controllers and multi-slot Ethernet-based compact controllers that can support TSN standards.
Smarter manufacturing
In China, starting in 2016, NI began cooperating with Industrie 4.0-Intelligent Factory Laboratory under Tongji University to co-build an NI Industrial Internet Laboratory. Cyberinsight, an NI partner in prognostics and health management (PHM), can use the NI platform to customize and develop an end-to-end IIoT product for customers. Applying the industrial intelligent algorithm engine enables platform and data analysis services to help Chinese industrial customers with real-time asset health management and predictive maintenance. Peng said NI seeks more companies in China engaged in Big Data analysis and data mining to provide IIoT hardware and software across industries. IIoT has progressed beyond theoretical concepts. IIoT platforms have been implemented in China and abroad, especially for machine state monitoring and controls, to which Big Data analytics brings unprecedented value. ce

igitalization can offer many advantages to process industries, such as new opportunities in process optimization and increases in plant efficiency. The Industrial Internet of Things (IIoT) offers predictive maintenance, asset information management, and open device configurability to a vertical that is just beginning to embrace Industrie 4.0. Process plants are built around myriad of moving parts, and increasing age brings inefficiencies. While utility prices rise, legacy plant equipment incrementally adds to upkeep costs. Legacy plants waste approximately 30% of the energy they consume. The convergence of information technology (IT) and operations technology (OT) data helps factory operations. This is where the buzz around IIoT starts making sense. As sensors and Internet-protocol-enabled devices proliferate, IIoT ultimately will dominate the factory floor.

Efficiency increase: 82%
If reports are to be believed, manufacturing plants experience an 82% efficiency increase with digitized processes. Addressing utility costs, a major Japanese chemical producer embedded 148 steam traps with sensors, leading to a 7% reduction in the cost of steam. With IIoT, plant operators can access more asset-related data. As IIoT links edge sensors and analytics, it will provide benefits by: CONTROL ENGINEERING

• Cost-effectively collecting data using wireless, low-energy sensors • Developing data-driven, strategic, actionable operational intelligence • Presenting this information to plant managers at the right time • Delivering performance improvements once corrective actions have been taken. Going by present standards, operators have been leveraging this information to transition from reactive maintenance activities to a more efficient predictive maintenance framework. Implementing efficient maintenance prioritization across multiple sites is a major hurdle that remains.
Maintenance, AI, optimization
Combining computerized maintenance management system software and data gathered through IIoT, maintenance personnel can monitor asset groups, specifying parameters for triggering alerts, automating responses, and work order generation by directly interfacing with cloud ERP. The process industries will find advantages in using artificial intelligence (AI). To increase plant safety, operators have been reducing manual intervention on the factory floor. Manufacturing systems that have capitalized on machine learning and predictive data analytics reportedly have improved production capacity by 20%, while lowering resource use by 4%. Human faculty for reasoning and logic are essential to manufacturing. As machines begin to think like we do, AI will become the central nervous system of the connected plant ecosystem, and using intelligence derived from to squeeze the maximum value out of every dollar spent. ce

ndustrial organizations want to maximize return on investment (ROI) by ensuring that automation assets are secure, future-proof, adhere to open standards, and integrate to existing assets—avoiding having to “rip and replace” current infrastructure. When it comes to programmable logic controllers (PLCs), advancements in embedded cybersecurity, increased integration to site-wide systems, and compliance to communication standards are increasing productivity and reliability.
Increased cybersecurity
Security breaches in control systems can lead to significant damages and harm to plant personnel and the public; damage to plant assets and equipment, causing lost production with unplanned downtime; and fines due to regulatory compliance issues, and damage to a company’s reputation, resulting in a loss of customer and investor confidence.

OPC UA reliability, integrated controls
A new breed of PLC provides an Industrial Internet of Things (IIoT)-ready open platform for better leveraging data across the plant infrastructure. The OPC Unified Architecture (UA) specification offers secure integration of a wide range of instruments, equipment, and software throughout an industrial enterprise. Interoperable multi-level and multiplatform open communication also supports flexibility and standardization with less hardware. PLC programmers can link information from controllers to other devices, systems, and business enterprise applications. PLC platforms embedded with OPC UA help make digitization a reality by using open-computing industry standards and streamlining an integrated plant architecture with communications to enterprise systems. Combining control systems from the same vendor can make coordination easier with fewer teams and direct access to system knowledge, resulting in faster setup, testing, and troubleshooting. Operational benefits can be achieved with a common human-machine interface across system applications. An integrated solution provides pre-built diagnostics, an integrated alarm summary, and history, trending and reporting on an automation infrastructure. With distributed control system and PLC implementations, users can simplify process operations, deploy equipment with a common lifecycle. Integration provides lifecycle cost savings, less engineering, and higher reliability. IIoT, Industrie 4.0, and other initiatives employ communication as a key element. Efficiency in combining intelligent systems, sensors, and actuators becomes more important. Controllers designed to be secure, IIoT-enabled edge devices provide an open platform that enables users to leverage data across assets to help reduce unplanned downtime and off-specification products. ce

T
he variety of micro-controllers emerging has been growing rapidly, with no signs of abating. These devices offer many capabilities, along with whole ecosystems of accessories that are also cost-effective. Consequently, interest in these products has moved from automation clubs and basement robot builders, to the point where some are considering their use in manufacturing. When an engineer seeks to solve a small industrial automation challenge, the traditional approach has been to use a programmable logic controller (PLC). While some engineers may consider a micro-controller, certain factors should be considered. Open-source board-level products resulting from the do-it-yourself electronics industry (the maker world), other micro-controllers, field-programmable gate array boards, and single-board computers have varying capabilities and limits, and, for discussion here, will be lumped under the heading of micro-controllers. Similarly, the characteristic attributions of PLCs and other industrial controllers do not apply to every model and manufacturer, although there is a high degree of consistency.

insisting on a full do-it-yourself experience may try to create the converter internally, but that can require extensive development time. PLCs are designed to work with industrial sensors and offer a wide range of I/O choices, so there should be little or no need for external conversion. Wiring directly to a PLC or I/O module will be easier since it is designed for this purpose. A PLC also will ensure a high degree of protection for the devices and circuits by building in isolation for relevant I/O points. An end user may be able to do the same, but this requires additional knowledge and increases complexity. Mounting and housing a micro-controller is a consideration, since it likely will be a naked board with pins for connections. The end user also must supply power and create terminals to attach external devices.
Other considerations
Micro-controllers are bare-bones devices, and other considerations include lack of operating system software routines, applications, and software housekeeping functions; software and hardware watchdog functions; data verification and safe mode; environment considerations such as shock and vibration, electromagnetic noise, corrosion, limited temperature range, and related testing; generic versus branded boards; longevity and migration paths; technical support; as well as reliability and safety. ce

Control system lifecycle Extending the lifecycle of a control system requires proper maintenance and effective lifecycle management practices. Seven tips can help.
I
f a control system is at the end of its lifecycle and a company can’t afford the time or expense of an upgrade to the whole system, some things can be done in the interim to increase the longevity of an aging system, independent of the system’s age. In most cases, a control system consists of much more than a few programmable logic controllers (PLCs). There are controllers, input/output (I/O) cards, a network infrastructure, gateways or interface devices to allow data to flow between systems, and human-machine interface (HMI) software applications or proprietary consoles. To maximize the lifecycle of a system, it’s important to have good preventive maintenance plans, and a plan for managing the dependence on aging components and software, which are essential to operation.
Automation maintenance: 7 tips
Keeping up with control system releases and properly maintaining the system over its lifecycle is essential to ensuring its reliability and continuous operation. This exercise can thwart the demands of time, manufacturing, and production schedules.
distributed components. Variable frequency drives, valve banks, remote I/O, etc., are all reliant on a solid network. In most cases, it makes sense to make this as robust as possible. Users should explore layout topologies, distributing loads, and fault tolerance using multiple links and switches.
4. Stay up to date: Every control system has a life span. Computers should typically be replaced every five to six years and controllers/hardware should be replaced as needed (while still available). Keeping up-to-date can involve upgrading computers and the control software. Companies that follow the latest version of software supplied by the vendor probably will be upgrading PCs more often due to enhancements and functions offered on the newer operating systems, which usually don’t support older hardware. 5. Virtualize: In most cases, it’s possible to virtualize the old system, which would allow users to limp by until a final solution is in place. This works well if you have good control hardware and need an immediate solution to HMI PC replacement problems.

power is a must to maintain longevity. Use an uninterruptible power supply (UPS) and run the critical components from it.
2. Environment:
Keeping tabs on the environment means factoring in temperature, humidity, and dust. Controlling the temperature and humidity around the components in the control system is critical. The warmer the cabinet, the shorter the life of the components inside (above a threshold temperature). This applies to computers as well. Accumulated dust can act as an insulator, keeping the cooling air from properly removing heat.
3. Network updates: The network is the backbone of the control system yet it is often the part most overlooked. The data has to make it from the processors to the server/HMI so it can be controlled. More and more systems are adopting Ethernet as the go-to choice for control of CONTROL ENGINEERING
Phased replacement: Replacement often consists of updating the HMI software to a package that works with the existing and new hardware. Users can replace hardware as part of a phased approach, running the new and old systems side-by-side on the new HMI software until the upgrade is complete and you have all-new hardware. This removes the vulnerability of the outdated computer hardware running legacy operating systems.
7. Plan ahead: Several years prior to when a control system is to be discontinued, users should begin the process of planning the next steps to ensure you minimize the potential for production outages. Most vendors offer migration paths. Using thin-clients is also a great way to help minimize the impact of replaced hardware because these are independent of operating systems. ce David Ward, integration/energy management engineer, Cross Company Integrated Systems.

hanging operating conditions in space creates difficulties for supplying reliable power to spacecraft. A property of biological systems, homeostasis, can resolve challenges by using multi-alternative principles: Multi-level structure and control, functions diversity and partition, and structure modularity. For example, the power supply system (PSS) of an orbital station contains alternative energy sources with a multi-level control structure. To embody the principle of modularity and partitioned functions, the general control zone is divided into non-overlapping active control ranges. Partitioning of functions, modularity, and the structure’s hierarchy excludes the possibility of a cascading increase in system failures and ensures uninterrupted station power supply in various flight modes. Reliable power for an orbital spacecraft is difficult due to significantly varying luminous flux densities, variable temperature, and shade on solar batteries, even when a PSS design has multiple redundancies. Experience in designing and exploitation of a PSS shows the need for active reorganization of the operation modes and the interaction of its modules, depending on the current flight conditions. That is, better control is needed.

the multi-alternative principles in critical functional modes. The subsystems of the main PSS (see diagram) are: • Solar batteries, the primary source of energy • A high voltage source located on the apparatus external to the space station and playing the role of a secondary energy source • Electrochemical accumulator batteries, which accumulate energy if there is an excess in the system, and returning energy if there is a shortage. Subsystems have automatic control circuits; interactions in operating modes are discussed online; eight graphics show subsystems and power controls.
Multi-alternative control
Analysis of the critical operating modes of the autonomous PSS of the space station shows that the survivability of the system under consideration is achieved as a result of application of the evolutionary principles of multi-alternative control. • Multi-levelness creates the diversity of behavioral strategies of the system by transferring control and distributing the power supply functions between the subsystems and within each of them, depending on the present situation. • Modularity reduces the possibility of cascade (technologically connected) development of an emergency situation and failure. • Functions partition ensures high efficiency of organized control channels with narrow functional purposes. On the basis of these principles, active redirection of the energy and information flows of the PSS and change in the strategy of how subsystems function in extreme situations are realized. ce

Wind industry sensing applications
Magnetostrictive sensors are used for position feedback in the closed-loop control for the pitch of rotor blades: they measure position with high accuracy under great aerodynamic forces and continuously changing wind conditions. To ensure the highest safety during maintenance, locking cylinders keep the rotor blades of wind turbine stationary and positioned precisely. The extending and retracting movement of the locking bolt makes the wind turbine lock and unlock. The detection of the locking/unlocking position can be monitored with sensors. They provide operation and functionality in difficult maintenance situations due to rotor height or in challenging offshore environments. As wind velocity and direction change, the pitch control adjusts the angle of the rotor blades by a few degrees to maximize the output for all wind speeds. When the wind velocity exceeds the maximum permissible generator output, the blades are adjusted away from the optimum position to reduce the aerodynamic efficiency and maintain constant rotation. Blades are turned back into the wind when wind speed drops again. Actively controlling the rotation speed enables peak efficiency, reduces the stress on the rotor and tower, and is the foundation for increased safety and longevity. ce Moira Lise, MTS Sensors.

S
afety technology and the professionals behind it provide a solid assurance the process and facility remain safe and sound. That is a vital element of process automation, but there can be more. An Aberdeen Group study on the three tiers of safety levels said the top tier is best in class with 90% overall equipment effectiveness (OEE), 0.2% repeat accident rate, 0.05% injury frequency rate, and 2% unscheduled asset downtime. The top tier represented 20% of the aggregate performance scorers. That compares to the laggard or third tier of performers that have a 76% OEE, 10% repeat accident rate, 3% injury frequency rate, and 14% unscheduled asset downtime. This category had 30% of the aggregate performance scorers. The middle is filled out by the rest with an 85% OEE, 2.4% repeat accident rate, 0.9% injury frequency rate, and 6% unscheduled asset downtime. Every 15 seconds a worker dies from a work-related accident or disease, said a report from the International Labour Organization. That adds up to 6,300 deaths per day or 2.3 million a year. In addition, every 15 seconds, 153 workers have a work-related accident. It is easy to ask why don’t more manufacturers think safety first? The answer is not easy; companies see safety as a cost and not a business enabler that can boost profits. That thinking may soon change. “There has to be a senior management commitment to viewing safety as more than a cost, but an opportunity to improve performance,” said Martin Turk, Schneider Electric’s director, downstream O&G global solutions architect. “There is a need for a belief—a commitment from the executive—to do something to improve performance.”
four times a day to find out what they are going to do to turn around profitability. To create a safety environment, there has to be a direct link between profitability and safety.” That is where real-time safety and operational profitability come into play. “What we are finding in most plants today is they are setting up their safety limit as a constant,” Martin said. “What if you can directly measure the safety risk and realize the plant’s normal safety threshold can be pushed a little because your equipment is in better shape? This way you can drive more profitability to the plant because of lower safety risk. By doing that, to a chief executive, you tied profitability to safety so there is a direct metric showing if you control and reduce safety risk you can drive more profitability. We believe that is the link to create a safety culture by mathematically showing how that can be done.” The biggest barrier to linking safety and profitability is being able to measure safety risk in real time. To do that, Martin suggested users look at operational safety measurement, conditional safety measurement, and conditional measures around an asset. ce Gregory Hale is the editor and founder of Industrial Safety and Security Source, a news and information website covering safety and security issues in the manufacturing automation sector.

Q: Can you discuss application of radar and ultrasonic sensors and transmitters? Christopher Thompson: Radar sensors are typically associated with measurement of liquid or bulk level in some type of container (such as a tank, vessel, silo, or hopper). The sensor emits a microwave pulse that is either directed down a fixed probe (guided wave) or into the open area of the container (noncontact). In both cases, the transmitter then detects the reflection time of the microwave pulse as it bounces back from the fluid or build solid level in the container. A guided wave also can detect interface levels in liquid-liquid applications, and its measurement is largely independent of the property changes that occur at various operating conditions. Noncontact radar sensors can be inhibited by use with some solids, fluids with low dielectric, substantial surface turbulence,

condensing vapor environments, and echoes from container walls or internals. Ultrasonic sensors operate on a similar principal as the radar, with the sensor measuring time-of-travel or reflection time of the ultrasonic pulse emitted. The sensor correlates this time to the liquid or bulk solid level in a container, or flow through a pipe. The flow sensor is typically used with liquids and gases, and the emitted ultrasound must be capable of penetrating through or being reflected from the material being sensed. Ultrasonic level sensors are fixed, but flowmeters can be either fixed or portable, inline, or clamp-on. Ultrasonic level sensors can be inhibited by use with some solids, foaming, interference, or echoes from container walls or internal, smoke and/or dust, and heavy vapors. Flow sensor applications depend highly on the fluid being metered. If there are any questions or uncertainties regarding the sensor, inquire into possible vendor testing, instrument trials or rentals, or an application warranty.

Frank Lamb: To prevent explosions and combustion in hazardous areas, sensors are housed in an explosion-proof enclosure or intrinsically safe “NAMUR” rated sensors are used. These sensors operate on less than 8 V dc to prevent sparking and often are connected through an intrinsic safety barrier. Q: Can you discuss accuracy considerations for gas flowmeters? Thompson: With most gas flowmeters, accuracy will depend on the material being sensed, the process conditions encountered, the installation location, operating range, and the technology selected. Condensing vapors are a challenge for most applications, so operating in a range that will minimize the likelihood of liquid droplets forming is important. Depending on the technology, turndown could impact not only the accuracy but ability to use the meter (e.g., vortex, turbine, or differential pressure). Particulate-laden gases also can pose a challenge for some meters, depending on the type and concentration of particulates. Proper temperature/pressure corrections

as well as proper flow distribution into the meter itself (e.g., sufficient conditioning or upstream/downstream straight runs) will impact differential pressure flowmeter accuracy, while thermal mass meters will struggle with streams containing variable composition, aerosols, droplets, etc. Flowmeter accuracy issues can be addressed by having an accurate description of the stream being sensed, a clear definition of the operating parameters, and an understanding of the potential technology limitations prior to sensor selection. Q: Can you discuss best questions to ask stakeholders when selecting sensors? Thompson: In general, many of the components of the sensor specification itself may come from the stakeholders, such as process conditions, stream composition, accuracy requirements, etc., and buy-in should be obtained that the values specified are accurate. Some additional questions include: 1) What’s the history with this application and sensors that have been used in the past? 2) Are there any lessons learned to incorporate into our design considerations? 3) Is there a preferred technology or make/ model that has been identified at the facility or elsewhere throughout the organization? 4) What are the accuracy, reliability, and range requirements for the sensor? 5) Are there any access or operating limitations based on the installation location (e.g., internal interferences, maintenance accessibility)? 6) What is the required sensor redundancy and what is the frequency of planned calibration? 7) Have all stream components been considered and accurately characterized opposite the proposed materials of construction? 8) If it is a replacement due to failure, has the root cause been determined and mitigated? 9) What type of local or remote indication is necessary for process control, and is there latency experienced from the instrument location opposite the control point? 10) Into what environment will the sensor and transmitter be installed (such as electrically classified hazardous locations, temperature extremes)? ce Edited by Mark T.

Update To The NFPA 70E Standard The National Fire Protection Association (NFPA) is a trade association that develops and maintains various standards and codes designed to prevent injury and economic loss caused by fire and electrical related hazards. The organization published NFPA 70E, the Standard for Electrical Safety in the Workplace and updates the standard every three years. One change in the latest version, NFPA 70E 2018, includes new language in Article 120.5 (7) about absence of voltage verification. This white paper examines the new NFPA 70E options for absence of voltage testing, reviews the advantages and limitations of various voltage testing and voltage indicator products, and explains how the VeriSafe™ Absence of Voltage Tester (AVT) complies with the new NFPA 70E requirements. Prior to NFPA 70E 2018, the process electrical workers would use to verify the absence of voltage in a panel or other electrical equipment required the use of an “…adequately rated test instrument…”, which was typically interpreted as a hand-held voltage tester. NFPA 70E, Article 120.5, Process for Establishing and Verifying an Electrically Safe Work Condition, has always contained a step to verify he absence of voltage. The 2018 edition includes an exception, also known as an approved alternative, to using a handheld test instrument. The new exception describes an absence of voltage tester (AVT). Part of the motivation for including this exception was to stimulate original solutions and development of new technology for safety applications and make testing for an absence of voltage safer and more efficient. For example, when performing the traditional method of using a hand-held voltage tester to check for an absence of voltage in a control panel, the door must be open to conduct the test. This exposes the electrical worker to potentially lethal voltages. However, implementing AVT devices allows the worker to verify the absence of voltage prior to opening the panel which reduces the risk of an electrical incident as well as reducing the complexity of testing with a hand-held tester. cs@panduit.com • www.panduit.com/verisafe

Sawmill Conveyor Lines: ABB Drives deliver reliable process control and a 5% increase in production efficiency Summary: At the Westas sawmill the production process is very long and conveyor intensive. The size and weight of materials varies greatly, starting with heavy logs and then transitioning to a range of smaller pieces. To keep the sequence of production processes running smoothly it is crucial that the speed and feeding of the conveyors adapt to the various products. A stop in some part of the process can affect things all the way to the beginning.
Challenge: Upgrade the conveyors that carry materials of varying sizes/weights through the long production processes, to gain greater speed control and performance efficiency without rebuilding the whole system.
Solution: Retrofit the existing conveyors with ABBs ACS580 general purpose variable speed drives.
Result: Achieve the desired results with a relatively small expenditure and a far better return on investment than complete machinery replacements: • Improved production efficiency by 5% : Better quality products, less waste, less energy usage and greater profits; • Reliable process control: Highly precise speed increases of 5 to 20% without using PLCs; • Easy commissioning and operation.
Instead of rebuilding the whole production line, Westas opted to invest in an automation upgrade to improve production efficiency. The upgrade included the log feeding, log metering and saw-line angle metering machines. The conveyors for each were retrofitted with ABBs ACS580 general purpose variable speed drives. The addition of the drives allowed the speed of the conveyors to be adjusted as required to accommodate the varying loads and to sync with the production processes. The ACS580s also improved production efficiency by approximately 5%, with a far better return on investment than completely replacing the conveyor lines. In a sawmill the efficient use of raw materials is the key, but energy is also a major variable cost. Utilizing ABB drives, Westas was able to achieve savings on both material and energy consumption, adding directly to the bottom line.

How Innovative Process Automation Quickly Doubled Production Summary: To meet growing market demand, International Foods purchased a brownfield site of a closed Ford Motor Company plant in St. Louis. Partnering with EPIC Process Systems, they built a new facility and expanded production for both liquid and powder food product lines.
Challenge: International Food Company needed a rapid expansion of their process and packaging lines due to increased customer demand. A new brownfield facility was acquired, creating a project with an accelerated schedule and several challenging sanitary requirements.
Solution: A series of sanitary systems were built off-site (modular construction) and automated under controlled conditions, allowing field construction to occur simultaneously. Modular engineering methods ensured high quality construction, system validation, and full startup before the target date.
EPIC ensured that all process and packaging equipment complied with stringent food and beverage sanitary requirements Title 21 CFR, Part 110 cGMP guidelines. Site and plant construction was simultaneously underway while system programming and fabrication was occurring at EPIC’s sanitary facility. Allen-Bradley PLC’s were integrated on all equipment, with a custom batch tracking software developed by EPIC for recipe management and formula tracking. Finished modules were shipped to the International Food Company plant, followed by a fast start up within three days of arrival. Each sanitary batching and blending system went through in-house, Factory Acceptance Testing (FAT) to ensure trouble free startup during installation. A team of EPIC’s in-house automation engineers were on site throughout installation and commissioning. Their presence helped ensure the process and packaging systems were running at specified parameters. They also assisted in training plant personnel on all new operating systems associated with the new plant equipment. The collaborative project resulted in successful startup, allowing International Foods to increase production, meeting demand for their growing product lines.
Result: The Allen Bradley PLC platform and custom batching system nearly doubled production capacity and product offerings, while also improving product tracking and quality control.

FASTechnology Group: Systems Integrator adds UPC Verification to Bagging Machines in Packaging Industry Summary: In the Consumer Packaged Goods industry, a simple mismatch of pre-printed package to product can quickly spiral into a safety concern for consumers, not to mention countless dollars lost on wasted products, recalls, and downtime. For example, a packaging line cannot have peanuts going into a potato chip bag. The risks of only checking the spool of film prior to running the line doesn’t always cut it. When FASTechnology Group was tasked with modifying existing production lines to verify the UPC of each and every bag, the company was able to use the latest in industrial controls across a wide array of technologies to deliver a solution to the customer.
Challenge:
Using the latest in PLC controls, HMI, and machine vision technology, as well as custom software and database development, FASTechnology Group created a system to read, compare and verify the UPC barcode of each and every product made against the plant’s ERP system.
The system combines an industrial logic controller, a machine vision barcode reader, and custom server-side software to cross-reference the physical UPC with the one in the Plant Management Software. As one of FASTech’s customers states: “Using this system, we are able to limit the pulling of jobs down from the plant management system to only those scheduled for the current shift. This keeps the user interface out on the plant floor clean, simple to use, and efficient.”
Result:

Power facility generates an automatic advantage with the Fluke 729 Automatic Pressure Calibrator Summary: Safe and efficient coal-fired power generation requires that all process transmitters and pressure switches be regularly calibrated to ensure that accurate pressure measurements are being fed back into the control system. So when an instrument supervisor at a U.S. coal-fired power generation plant recently needed to replace a pressure calibrator, he chose the Fluke 729 Automatic Pressure Calibrator. He chose the 729 for its: • Built-in automatic pressure pump that generates and controls pressure up to 300 psi • Ability to document applied pressure, measured mA, and % error for multiple test points in one set up
Challenge: An instrumentation supervisor at a coal-fired power generation plant needed to replace an old failed pressure calibrator used to maintain and troubleshoot several hundred process instruments.
Solution: He purchased a Fluke 729 Automatic Pressure Calibrator with a built in electric pump that automatically generates and regulates pressure up to 300 psi and includes HART communication.
Result: Now, the company’s instrumentation technicians need only carry one tool to quickly and accurately test multiple pressure points on switches and transmitters, rather than up to four tools required previously. This is projected to enable them to calibrate approximately 20% more instruments per route.
• Capacity to save measurements to the instrument. His technicians just type in the pressure range, set the % error, and hit the start button. The 729 automatically regulates the pressure. It even compensates for small leaks using stored compressed air and miniature air valves. This saves time and reduces the number of pressure calibration tools that instrumentation technicians have to carry, from four to one. The instrumentation supervisor estimates that using the Fluke 729, allows his technicians to calibrate approximately 20% more instruments per route. This increased efficiency saves a significant amount of troubleshooting and preventive maintenance time, and reduces the amount of time an instrument is offline for testing.

Teel Plastics Reduces Downtime and Increases Efficiency with IoT Gateway for KEPServerEX® Summary: The Teel Plastics facility has ten manufacturing lines that produce different products throughout the day. Each line requires a custom recipe for every product— and employees had to memorize multiple recipes during a single shift. Teel needed a solution that would control all recipe complexities electronically, in order to reduce downtime and product flaws caused by human error. Teel found that Kepware’s IoT Gateway for KEPServerEX was the only product that provided a seamless, reliable, and scalable solution for controlling all the essential recipe components through a single web interface.
Challenge: Teel Plastics employees memorized and applied multiple complex, changing recipes during a single shift. But even a minuscule recipe mistake caused downtime and reduced product quality. Teel needed to control all recipes electronically, in order to reduce human error and its downstream impact.
Solution: Kepware’s IoT Gateway for KEPServerEX was the only solution that could address all of Teel’s needs. Kepware’s IoT Gateway also had the interoperability to connect to Teel’s entire range of diverse PLCs.
Result: Teel has reduced set-up times by 30 percent, all but eliminated human error, increased process efficiency, improved product quality, and increased visibility across the enterprise.
With the IoT Gateway providing device interconnectivity to multiple PLCs—including Allen-Bradley and Siemens—Teel drastically reduced human error, downtime, and product flaws. Efficiency was also increased in many ways— for example, processes that previously required 40 clicks now take one single click. With in-depth plant floor data from the IoT Gateway, Teel engineers have also made their recipes much more efficient. Seamlessly aggregated data enables operators to perform predictive maintenance and leadership to make more informed decisions on recipes—so Teel can produce greater output at a much higher quality. For example, prior to the IoT Gateway, one line was completing 18 units a minute. Now, it is outputting 35 units a minute—nearly doubling its capacity.

Heater Differential Temperature Monitoring and Alarming Using Associated IS Summary: The customer needed to measure inlet and outlet temperature of a process heater using existing three-wire RTDs and provide a 4-20mA process variable signal, representing the differential temperature across the heater, to the BPCS controller. The measurements are in a hazardous area and plant standards require a certified IS system. Utilizing the associated IS and dual RTD input capability of the THZ3 temperature transmitter, the heater’s differential temperature 4-20mA signal was wired in series to a local alarm trip and host BPCS.
Challenge: Measure inlet and outlet temperature of a process heater using existing three-wire RTDs and provide a 4-20mA process variable signal, representing the differential temperature across the heater, to the Basic Process Control System (BPCS). The measurements are in a hazardous area and plant standards require the use of a certified IS system.
Solution: The THZ3-DIN Dual Input Temperature Transmitter with the Associated IS (AIS) option, and SPA2 Alarm Trip with self diagnostics capability and local display/alarm status indicators.
Result:
The process side alarm trip provided visual and audible heater failure warning and indication while the host BPCS maintained primary control and master alarming capability. Additionally the HART diagnostics from the THZ3 allowed the BPCS to constantly monitor key parameters such as RTD drift, broken sensors and critical transmitter diagnostics. Providing a local process side alarm trip substantially saved wiring and operation costs since new signal wires (RTD and alarm) didn’t have to be pulled to support the newly desired local alarms, two IS barriers were not needed for the RTD wires back at the BPCS location, sensor diagnostics continuously monitored by the BPCS and local differential temperature calculation and indication can now be done in the field.
Successful measurements to the BPCS of inlet and outlet temperature, temperature differential, sensor diagnostics, transmitter diagnostics using HART to the BPCS.

WebPort Remote Access Optimizes Manpower and Chemical Usage in Water Features Summary:
Challenge: Optimize the manpower spent to control, monitor and manage large water features.
Solution: Install a WebPort remote access unit with cellular modem for: secure remote access to the system’s controller, event notifications to quickly notify personnel of chemical imbalances and easy data access to review meaningful data and optimize decision making.
Result: After installing WebPort, the chemistry of the water features is more consistent and the need for manual testing has declined. Data is now displayed using dashboards to monitor the health of the overall system which has improved trouble shooting and the ability to foresee future maintenance needs.
An OEM was responsible for managing a large volume water feature through daily testing and the use of chemical controller more commonly known as an Oxidation-Reduction Potential (ORP) controller. Due to the complicated chemistry, environmental factors and inherent challenges with large volume systems, daily testing was required. Unfortunately, testing often returned poor results and indicated inconsistent chemical usage. Depending on treatment, odor problems, algae growth and excess chemical costs were all potential outcomes if not managed with additional manpower. Thus, a better system for monitoring and managing the water feature was needed. Spectrum Controls worked closely with the OEM to understand their needs and deliver a solution that has improved their management of large volume water features. By integrating a WebPort remote access unit, the OEM can now remotely access their system using a cellular or Ethernet connection and download data without being on-site. Dashboards are also being delivered to personnel, allowing data to be reviewed quickly so chemical adjustments can be made to maintain an ideal water treatment program. The ability to collect data and monitor the system has further led to improved trouble shooting and the ability to foresee future maintenance needs. Today, the water feature has stabilized, and decreases in chemical usage and manual testing has returned significant savings.

INNOVATIONS
BACK TO BASICS Jessica Potts, TopEngineer
Six traits for excellent engineers Engineers who aspire to be great have common traits such as good communication skills, a heightened curiosity about their profession, and good analytical and mathematical abilities.
G
reat engineers are competent, creative, yet logically practical, and incredibly influential on everyone’s daily lives. For some, the thought of being an engineer seems like an unattainable and distant goal that can never be achieved. Great engineers are a rare breed. Six traits make some engineers rise above the rest.
1. Natural curiousity
M More INNOVATIONS
KEYWORDS:
engineers, STEM Great engineers are rare, but those who develop their skills and become well-rounded can hope to become great. Great engineers are detail-oriented and selforganized as well as constantly curious about the world around them. It’s also important for an engineer to be good at communication, analysis, and mathematics.

CONSIDER THIS What other skills or traits should a great engineer have?
48
•
Engineers must be able to observe a process, structure, machine, or system and determine how it works and how they can improve upon it. Curiosity is a beneficial quality in nearly every industry because it indicates interest and drives creativity. Engineers must have the energy and determination to research and understand problems and their solutions and it starts with that natural curiosity. Kids who grew up asking, “Why?” are good candidates for engineering programs, but those who excel at engineering are more often those who pursue “Why?” to “Oh, that’s why.” Asking questions isn’t enough for an engineer; they want to find out the answer and are willing to spend as much as time it takes until they reach a satisfying conclusion.
2. Self-organized
Engineering teams usually have managers tasked with keeping workers on course, but most engineers must be able to manage projects. Often, engineering projects last months or years, and ideas or discoveries made long ago must be readily available for application. By displaying project management skills, it is more likely to obtain raises and promotions. Selforganization is one of the few top engineering qualities that can be improved upon with concerted effort.
3. Detail-orientation
To succeed in engineering, the person needs to be able to parse details and organize them to create an effective machine—process, system, structure. This is part of an engineer’s daily responsibilities and such attention to detail allows engineers to analyze intricate problems and produce high-quality work.
4. Good analytical skills
There is a world of difference between something

CONTROL ENGINEERING
working and something working well. Engineers are typically tasked with finding the most efficient solution to a problem, which requires being able to analyze the issue and all possible answers to identify the best course of action. Analytical ability comes in many shapes and forms; even English majors must be analytical in some sense. Engineers’ analytical minds are constantly running, revising plans to ensure the best possible outcomes. People who are able to logically pick problems apart and discover optimal solutions on the fly have the right stuff as a potential engineer.
5. Strong mathematical skills
Every engineering discipline, from computer engineering to petroleum engineering, works with numbers and equations. At its very core, engineering is the application of theoretical mathematics to the physical world to solve everyday problems. Engineering programs often are rigorous in mathematical studies, putting students through advanced calculus, statistics, trigonometry, and geometry. Students curious about engineering should be confident and comfortable in writing and using formulas to solve problems because it will be required after graduation.
6. Good communication skills
While engineers may seem to be asocial, numbers-focused professionals, they are far from hermits. Engineers almost always work in teams, which means communication between team members occurs on a regular basis. Communication failures within engineering result in low-quality machines, inefficient systems, and worse. So the ability to express thoughts and opinions must be finely honed. As with project management skills, engineers who prove themselves adept at communication often excel in management positions. Aboveaverage communications abilities will help with an advanced education to prepare for an accelerated career in engineering. ce
