Tracking the developments! Wireless in homes was probably a rare concept ten years back. However, today, most of us count on it for not only computers, tablets, and phones, but also for music & television. Similarly, industrial wireless, at one time, was only for “must have” applications such as overhead cranes or automatic guided vehicles, rotating equipment, etc. Today, it’s moving rapidly from those few, critical “point” solutions to a “must-have” ingredient on production floor. Workers can now take the control room with them as they address production needs wherever they are. Though wireless infrastructures provide very good reliability and flexibility, factories and other industrial facilities have long been a challenge for wireless deployments. The Cover Story in this issue provides the tips for a successful execution of wireless infrastructure projects. Power plant control systems, over the years, have evolved from DCS-centered platforms with proprietary software, to totally integrated plant automation systems with almost unlimited connectivity. In the future, control systems will no longer control the process — they will supervise it! These developments bring in their own set of challenges and requirements when it comes to modernising a power plant, especially for a country like India where the power demand-supply gap is huge. Check out the Round-table to know more about it. The Industry Focus this time is Food & Beverage, where the articles talk on the latest trends in automation solutions and components that help address the issues related to changing consumer preferences and increasing government regulations. Hope you will find the contents useful and interesting!

SCHUNK robot competition held in Germany
Making India global supply centre of valves
The SCHUNK robot competition was recently held at Germany, where 14 students of the Hölderlin Gymnasium Lauffen competed at the European Robotics Week. There were two mixed teams who had to perform a series of several tasks with a robot they designed. Several cylinders had to be collected, and, in order to win this competition, had to be converted into a penalty kick. The competition was split into two parts—subtasks had to be solved first and then the complete sequence without converting the robot. Both teams Both teams designed different robot designed different robot models models with impressive creativity, with impressive creativity, technical technical skill, and team spirit skill, team spirit, and were optimised in several test series. The Green Team was declared the winner. “It was our aim that young people should be inspired by the possibilities of robotics, and to show them the options of mechatronic solutions. Both teams convinced with great commitment, curiosity, and smart ideas,” said Martin Aichert, Trainer—Automation Technology & Mechatronics, SCHUNK.
The CII Valves National Conference 2014 was recently held in Mumbai, with the theme—Going Global. I S Malhotra, Chairman - Valves & Actuators Division, CII & Pentair Valves and Controls opined that making India a global supply centre of valves is a part of the “Make in India” programme. “We need to upgrade our infrastructure so that India can produce The CII Valves National Conference 2014 high-end engineered valves. was based on the theme ‘Going Global’ China is no threat since these valves are for the high end. The Indian valve industry was worth $2 billion, while the global market was worth $60 billion, which only showed the growth potential,” he added. According to Anil Gupta, Executive Director (QA&I), National Thermal Power Corporation (NTPC), the company would be generating `1.28 lakh megawatt power and would thus, need different valves. “Valves should have zero defects, which would delight customers and help this sector in going global. As India is building super critical power plants, the valves should withstand high temperature and pressure, and exhibit high quality and total reliability.”

“Focus is on energy saving technologies” Ajay Bhargava, Managing Director, Rittal India, briefs on the current scenario of power distribution and climate control in India and the latest trends emerging in this sector, during an interview with Megha Roy How do you look at the current scenario of power distribution and climate control in India? What are the major challenges faced in this sector? Power distribution is critical and is required across industries & verticals. The standards on power distribution are getting higher every day. Safety and reliability are the key attributes that will shape this business in the future. There are global standards like 61349, increasingly specified by customers. The biggest challenge for the industry is to be aware of the safety issues and implement the right design to ensure environment’s safety. Industrial climate control is another critical subject in few industries like automotive, steel, textile, O&G, etc. Now, the focus has been on energy saving technologies as cooling is a vital requirement in most of the industries. Our company has already launched high-end products like Blue E, LCP for energy savings. Please brief us on the RiTherm app. Our company has multiple configurators that are created to help customers size cooling units. RiTherm is one such software that is used to calculate heat load based on a specific customer requirement. Keeping in mind the technology driven market in India, what are the innovations expected from your company? Our focus is to create multiple cooling solutions. We have launched water based cooling solutions for a very high heat load called industrial LCP. We have also developed new concepts in IT data centre space, where we have preconfigured data centres. This can be implemented in a timeline of 3 to 4 months. Our key focus has been energy efficiency, safety & fast implementation. We are also working to create solutions from engineering to automation & moving towards Industry 4.0. Our recent acquisition of Keisling completes the value chain from Eplan to Rittal to Kiesling. Are there any plans for further manufacturing expansion in the Indian market? We are continuously working to increase our manufacturing

capacities in India. We have invested in upgrading our machines in the current factory that will increase capacities by 30 to 40%. We will evaluate the need for a second factory in 2016 as markets are expected to show substantial growth in the next 3 to 5 years. Given that the global economies are on the mend and a new government at the centre brings renewed hope, what are your views on the changing Indian economy? We are optimistic on the economic growth in the next 5 years. Investment climate is changing faster than what we expected. Fortunately, the central government is absolute majority and they can take some tough decision on labour, land & tax reforms that will boost industry confidence. What are the latest trends witnessed in your sector? We are seeing changes across segments due to globalisation & many of our customers have global customers. Therefore, customers are increasingly demanding a higher quality, standardisation, products meeting global benchmarks, reduced lead times and high energy efficient products. What are your global market expectations in 2014-15 term? In process industries like O&G, food, pulp & paper and steel, we see a moderate growth. However, many MNCs are using India as a manufacturing base for global markets and we see excellent business in the export segment. In the energy sector, which includes conventional power and renewable sector, we see a good growth in the coal-based power plants. Wind energy will grow slowly but solar energy will be a big boost to Rittal. The telecom and infrastructure sector is growing at a double digit due to the 3G & 4G roll-out by many leading telco players. For infrastructure, a big growth has been observed in the metro sector. However, in the automotive & ancillaries, we will see a slow growth in 2015. This is likely to speed up from 2016 onwards. Also, we see a good growth in the IT sector, primarily driven out of cloud computing and e-commerce space that will need a high level of IT infrastructure. ☐ > MORE@CLICK ADI03608 | www.AandD24.in

Wi-Fi is now present everywhere and people have become This causes latency in the network. If you plan to connect many comfortable using it for just about any application. For example, devices to your industrial wireless network, then you should many systems designers are choosing to move their industrial also plan to add multiple access points to allow different clients applications from wired Ethernet to wireless utilising Wi-Fi. to use different access points, and thereby reduce the number The advantages of moving to a wireless design are numerous. of collisions on the wireless network. Wireless allows for client devices to be located in difficult to Tip 3: Know how your application will send and receive data reach areas, and it saves on installation and wiring costs in — Many industrial protocols send small packets of data that are remote locations. The advantage is not to re-wire the plant only a couple hundred bytes long. Other applications, such as infrastructure when relocating machines on the plant floor. for video or data storage utilise large blocks of data that require Thus, it is easy to expand as additional devices are required. transmitting thousands of bytes. Knowing the characteristics There are many different Wi-Fi technologies that can be used of how your application will use the network allows you to in industrial applications. Whether it is an existing application make an informed decision about which Wi-Fi technology is or a new design, an engineer must look at the application best suited for the intended application. For example, 802.11n requirements to make informed decisions regarding which is better suited for applications that need to transfer large technology to use. When deciding to move from a wired to a amounts of data since it contains features that help to optimise wireless infrastructure, here are the following tips to ensure large transfers. One such feature supported by 802.11n is called Block Acknowledge. This feature lowers the amount of that the design is successful. overhead in the wireless channel by allowing the receiving device to send an acknowledgement after many transfers by Ensuring successful design the sender. The result is better bandwidth utilisation. By Tip 1: Know your application’s throughput requirements — comparison, 802.11a/b/g sends an acknowledgement after To know the data rate that an application’s client devices will every transfer. send and receive is critical for planning the network. This Tip 4: Know which protocols the application plans to use — information will be used to determine things like which Wi-Fi Industrial protocols and other networked applications use TCP technology to use, and how many access points will be required for control applications or when reliability is critical and to provide the desired throughput. In a Wi-Fi system, the message loss is not acceptable. This is because TCP allows the actual throughput that is available to the user’s application is receiver to request that missing or corrupted packets be resent. generally about 50 to 60% of the overall bandwidth of the TCP is known as a reliable protocol. Contrast this with UDP, Wi-Fi technology selected. This is due to control and which is a connectionless protocol. This means the sender will management overhead in Wi-Fi systems. If the application transmit one packet after another without worrying whether needs more than what is available, then the application will not or not the packets were transmitted successfully. On wired work. networks, typically there is little to no packet loss and the low Tip 2: Know how many clients will be accessing the Wi-Fi overhead of UDP can be taken advantage of. However, many network — This tip goes hand-in-hand with the application other factors need to be considered on wireless networks, such throughput requirement discussed in Tip 1. Wi-Fi works in a as client roaming or RF interference, which can corrupt packets manner similar to how Ethernet hubs work. That is, Wi-Fi uses in transit. While 802.11 has the ability to retry transmissions a single collision zone for all the devices connected to the Wi- that it does not receive an acknowledgement for, depending on Fi network. This means that only one device can transmit at a the length of time the interference lasts, packets can still get time, and all the other devices must wait until the network is lost. What this means is that an application’s sensitivity or idle to transmit. When multiple devices try to transmit at the tolerance to packet loss must be considered. To mitigate this same time, there is a higher chance that collisions could occur. potential loss, highly available transmission features, such as

Additional access points increase the overall available throughput
Data is sent on both client links, providing redundancy and noise immunity
Moxa’s dual redundant packet solutions, can be employed to avoid this problem. When migrating to a wireless transmission medium for existing applications, application designers may need to tweak the mechanisms used for transmitting data, or make other adjustments. Tip 5: Determine the capabilities of the client devices that will be deployed on your network — Will the client devices all use the same technology or will there be a mix? Decisions regarding which devices will be supported are critical in maintaining application throughput. For example, if both 802.11b and 802.11g devices need to be supported, there will be less overall throughput on the wireless channel. This is due to the fact that the access point will have to slow down to 802.11b speeds when communicating with those clients. The time it takes to perform transfers at the lower rate steals time from the higher performing clients and limits their overall throughput on the network. If mixed mode operation is required, make sure you have enough throughput to support the application. If you can avoid supporting legacy devices, by all means do so, and limit the access point to only support a particular wireless technology to improve performance. For example, limiting the access point to 802.11g only or 802.11n will improve performance by not allowing legacy devices to connect to the access point. Tip 6: Plan for throughput — Knowing how much throughput your client application needs is critical in planning how many access points you need to install. Just because you have selected 802.11n and can support up to 300 Mbps of available bandwidth does not mean that every signal from every access point will transmit at 300 Mbps. The farther a client radio is from the access point the weaker the signal will be, and as the signal gets weaker, it gets closer and closer to the noise floor. The difference between the signal and the noise floor is the signal to noise ratio. A high signal to noise ratio means that a higher performing modulation and coding scheme can be used by the radios. As the signal to noise ratio degrades, the radios must utilise a lower performing modulation and coding scheme to
22
coverstory_Dec14-Jan15.indd 22
deal with the interference on the channel. This is called dynamic rate switching. This means that the farther the client is from the access point the lower throughput it can achieve. If your application throughput needs are high, then you must design your wireless network with more access points in closer proximity to the client radio’s location, since doing so will ensure that the radio will be able to sustain higher data rates. Tip 7: Know the application roaming needs — With industrial wireless networks, it is common for clients to move about in a facility. Clients are often used for location tracking or for obtaining the GPS coordinates of an object’s next location. In other cases, the clients are used for machine control on moving conveyors, rail cars, or cranes. The system designer should identify the latency the end application can tolerate while objects move between access points. When a client roams from one access point to another, the time it takes to connect to the new access point introduces a transmission delay. With commonly used Wi-Fi clients such as computers, the delay could be several seconds. If the application requires fast roaming, then plan on using Turbo Roaming in the design. This means that the client must be a Moxa client radio. Turbo Roaming can provide as fast as 100 ms roaming between access points, and if faster roaming is required, then consider a controller based approach such as the Moxa WAC. The wireless controller approach allows for 50 ms roaming for clients. Tip 8: Know the characteristics of the environment — Industrial applications are notorious for using machines that can cause RF interference. In addition, industrial applications are often housed in buildings made of metal, or are full of reflective materials. Utilising 802.11a or 802.11n in the 5 GHz band can help to avoid the interference issues of the overloaded 2.4 GHz band. However, as the frequency increases, the range and penetrating power of the signal decreases. This means that you will need more access points or higher gain antennas to obtain the same coverage as in the 2.4 GHz band. It is a good idea to use two antennas per radio in these environments. Two antennas allow the radio to take advantage of the diversity

Throughput (Mbps) decreases as the client gets farther from the access point
Turbo Roaming provides faster handoff between access points
antenna system, which can help manage reflected Tip 9: Know how to handle directly connected vs external antennas — It is common in enterprise or office environments for the access point to utilise built in antennas or directly connected antennas. These are usually low gain solutions in the 2 to 4 dB range. In industrial environments, it is not uncommon to have the radio mounted inside a control cabinet connected to antennas mounted on the outside or on a pole. In these situations, the engineer must pay close attention to the gain of the antennas and account for all the losses due to the cable and connectors used. In short cable runs, using LMR-200 cable provides for acceptable low signal attenuation. For longer cable runs, make sure to use LMR-400 or above to minimise the losses. For example, a 3 metre LMR-200 cable will have a combined cable/connector loss of 1.9 dB at 2.4 GHz and 2.8 dB at 5 GHz. The same solution using LMR-400 cable has less than half the attenuation. For optimum performance, make sure to minimise and match the lengths of the cables to each remote antenna connected to the radio. Tip 10: Design your channel allocation plan — When using more than one access point or when there are other access points in the area, it is important to identify the channels that will be utilised on each adjacent access point. When doing this, it is important to avoid using the same channel as an adjacent access point. In the 2.4 GHz range only three channels do not overlap. These are channels 1, 6, and 11. If at all possible, make sure to stagger the access points in these channels. This will minimize a kind of interference known as co-channel interference. When using the 5 GHz range, each channel is non-overlapping if you are using a 20 MHz channel width. This is known as HT20 mode. If the access point is using 802.11n with 40 MHz channel bonding (known as HT40), then you need to stagger access points every two channels to avoid overlap. Tip 11: Pre-plan your access point placement using a predictive site survey — For applications that must utilise
24
coverstory_Dec14-Jan15.indd 24
multiple access points to provide coverage, it is most helpful to use a software tool to provide a preliminary plan for access point locations. Doing so can result in a big time savings later on when visiting the site to perform an actual site survey. These tools typically take in a floor plan of the facility. Using data from the planned access points and clients in use, as well as building materials at the site, the predictive site survey can provide a placement plan for the site as well as the number of access points required to provide the throughput the end application needs. Tip 12: Perform an on-site survey to identify access point locations — Although predictive site surveys can be useful, they do not take in account the obstacles, machinery, equipment, and other radiating devices inside the building, which is why it is essential to do an on-site survey. Once you have a plan for where you want to deploy the access points, visit the site and perform measurements using the actual radios and antennas that will be used in the deployment. Using the preplan as a guide, measure signal levels using the actual devices you plan to use in the deployment to verify coverage. Try to maintain a line of site between the access point and client radios wherever possible. A variety of site survey tools are available on the market for measuring signal levels to create a heat map of the actual coverage in the area and for identifying problem areas. In the absence of advanced site survey tools, plan a 15 to 20 per cent overlap between adjacent AP cells at the minimum data rate required by the application. Tip 13: Check your work and verify throughput— After the radios are deployed verify the throughput in the network at various locations. Use a software utility such as jperf to measure throughput and verify that adequate throughput exists at edge cases in the Wi-Fi cell boundaries. These tips ensure that the wireless deployment is successful. ☐ > MORE@CLICK ADI03610 | www.AandD24.in

“Business Analytics to play larger role in business operations” Arundhati Bhattacharya, General Manager (PE-C&I) & CTF (Muzaffarpur & Darlipali Projects), NTPC – India’s largest power company, in this interview with Sumedha Mahorey, highlights her experience with automation service providers (ASPs), and the various critical aspects of the use of latest automation tools for power generation. Brief us on the challenges faced by NTPC while executing the automation/modernisation projects. How did you manage to overcome these challenges with the help of NTPC’s own experts as well as automation service providers (ASPs)? C&I in terms of overall project cost is only 3-4%, whereas its impact in the overall operations is quite substantial. This makes the challenges multi-fold – ensuring quality, speedy implementation and easy maintainability while keeping pace with technology. As an example, one such philosophy adopted

for improved site maintenance was single DCS platform for main plant BOP & all offsite areas. But obtaining data of offsite equipment from the OEM and doing in-house engineering for these areas is by no means an easy task, especially with the minimal resources. Similarly, in the project construction phase, C&I has a daunting task of maintaining erection quality while adhering to stringent timelines, as typically it is the last in the execution sequence. This makes accurate engineering and testing a pre-requisite.

“Advanced controls or APC as it is termed in automation parlance, has a huge potential in terms of operation cost savings; as it directly intervenes with the closed loop controls but it requires equally huge efforts on the part of the APC vendor to realise its benefits” Arundhati Bhattacharya
Again, modernisation projects (i.e. R&M jobs) have challenges of execution in the brief shutdown period. But thanks to the in-house engineering and meticulous planning of our own experts as well the support provided by automation service providers, C&I R&M jobs have been executed in the given short time span; some as less than 35 days making it a benchmark in project execution. Even in the power project phase, there has been no delay on account of C&I.
we have advanced controls for steam temperature, but in other areas, we have a long way to go. Also, training in this niche area needs augmentation. Please elaborate on the need for business analytics in the power generation business. Can you share any measures implemented or benefits derived by NTPC with the use of business analytics? Considering the challenges of the current scenario of power generation business, especially the new regulatory regime, business analytics is likely to play a larger role in the business operations of power generation companies. Already, Enterprise resource planning (ERP) systems are in place in NTPC where data (including real-time data) is leveraged to optimise several business processes like operations, maintenance, engineering, finance, ultimately increasing the profitability. Of course, scope for further improvements is always there.
How has been your experience with ASPs so far? What are your expectations in terms of making an effective win-win partnership with them? Our experience with automation service providers have been by & large good. Probably, NTPC is one such organisation which got the unique opportunity of working with multiple DCS vendors (more than 8-9). This has helped us to consolidate our operational requirements and implement it in different systems in an optimised way.

ReVAMping the power industry Highlighting the latest developments in industrial automation and IT solutions for the Indian power sector, this feature discusses the views of industry players to help the industry modernise and enable efficient operations in the coming years... As the global demand for power continues to outstrip supply, expanding the power generation capacity becomes quintessential. This calls for an efficient power generation system to be established and sustained. However, the challenges that confront the Indian power industry, such as, widening demand-supply gap in power generation, low per capita power consumption and poor risk management necessitate greater utilisation of automation and information technologies for its efficient operation & management. As such, it becomes imperative that breakthrough automation and information technologies are leveraged to the maximum towards this objective.

evolved from DCS-centered platforms (distributed control system) with proprietary software, to open systems using industry standard hardware and software, and then to totally integrated plant automation systems with almost unlimited connectivity and the ability to interrogate field instruments from many different manufacturers. Sharing his thoughts on the changes experienced in the power industry, Ganapathiraman opined that unified architecture is the next big thing. “It is an important step, especially when it comes to the supercritical power plants. In a thermal power plant, DCS with fully integrated turbine and boiler control system provides a common engineering & operator environment. Under such a platform, along with flexibility in operations, accurate process information can be leveraged and delivered at the right time to the right person within an individual plant, and possibly across various geographically dispersed units, further enabling operational excellence and higher reliability.” On the other hand, Nair focuses on the next phase of change that is quickly catching up, the emergence of software centric hardware platforms, with better computation, control & communication power. “These 3Cs together make the platform turn into a state-of-the-art cyber physical system (CPS). Currently, though the communication protocols between various IEDs are standardised, the IED(intelligent electronic devices) or other computing devices in the power plant is still a black box. A software centric automation platform like National Instrument CompactRIO system is changing the way these IEDs are build, making it more open and flexible. Using such technologies, the same platform with appropriate I/O can be modified into various kinds of power devices like PMUs, DCU, bay controllers, condition monitoring systems, etc.” Considering the technology driven market in India, it has become imperative to have a technological presence in every sector. As such, when it comes to the power industry, it has been observed that Internet of Things and smart grid concepts will make the industry experience various developments.
A&D India | Dec’14-Jan’15
Round-Table_Dec Jan 15.indd 29
According to Vuppala, such systems will be proactive in predicting the issues much earlier before the problem occurs. “Early warning system for wide area system stability, real time monitoring for situational awareness are few examples in that direction. With this, operators are playing the role of supervisors rather than controller of the system. We can control the system from anywhere but poses the challenges of security, which needs to be taken care of. Besides, concept of virtual power plants can provide more flexibility and efficiency and it can do load aware power generation with short notice. Micros-grid with small distributed power generation plants and consumers becoming prosumers (producers & consumers) is another trend observed these days,” he said.
Addressing the key challenges According to Ganapathiraman, the demand supply gap in the Indian power generation necessitates capacity augmentation to be done at a quicker pace compared to developed economies. “From the present capacity of around 243 GW, India plans to add 76 GW by 2017 and additional 93 GW by 2022,” he said. However, when compared to developed countries, it has been observed that the cost per unit of power is more in India. As such, it creates enough scope to improve on low cost of operation & maintenance. “For safety and risk management, the major black-out in 2012 indicates lack of coordination in operating the power grid. Various organisations such as TSDSI (Telecommunications Standards Development Society, India) and ISGF (India Smart Grid Forum) are working towards preparing the standards for India as well as participating in international standard bodies. Compared to developed countries, we need smart products at lower cost to support massive rollouts,” asserted Vuppala. In fact, it is not only the low cost. Much needs to be addressed on maintaining the structure and productivity of the Indian power sector too. Therefore, renovation and modernisation of power plants is critical for efficient running

trips. Further, virtual technology and simulation of control systems can be used in operator training programs to keep the operator aware of dynamic plant scenarios,” he added. When it comes to infrastructure, Nair opined that the availability of communication networks like FO or GSM will allow the latest IED to be installed in remote locations and be networked to servers, making data accessible at a central location. “Training plays a major role in the modernisation program. There has to be a good hand-holding between academia & industry to train engineers on the latest technologies. We need to have a pool of trained engineers who can analyse the large amount of data that these networked IEDs generate in order to make the whole system work more effectively.

It goes without saying that India is witnessing a modernisation spree. Same applies to the power sector. As such, the power plants can be modernised through automated devices and control systems. “It needs to deploy new M2M devices for real time monitoring of vibration, speed, turbine protection and synchronisation. When these power plants are installed with automated devices and control systems, the plant operators should be trained to respond quickly for the system raised alerts to increase safety and reliability of the plant.

the largest or the biggest data is not generated by digital or social media but by equipment’s like turbines and energy meters. If the data generated by all turbines in the power plants that we have in the country is clubbed with the data generated by PMUs on the transmission grid along with the ones generated by AMR systems on the distribution grid then these analog data generated are much bigger than the ones generated by digital media for an equal timespan.” In this regard, GE has come up with Predix – the software platform for the Industrial Internet that enables predictive insights from Big Data, business analytics and state-of-the-art user experience. “To put it into perspective, if we are able to offer just 1% of fuel savings for all gas power plants, it would mean saving $ 66 billion over a period of 15 years. The potential is huge,” said Marathe.
Integrating suppliers and users Automation solution providers can have specific devices to power plant sectors for synchronisation, vibration monitoring, speed control, load control and turbine protection. Underlining this thought, Vuppala opined that there is a role for system integrators in customising automation solution to the need of the users. “Vendor selection has moved beyond the conventional terms of product/service offerings, as customers want a partner who can address more than their technology requirements. Moreover, a differentiated value proposition by the vendor built on a consultative approach helps in bridging the end user-client partnership expectations,” added Ganapathiraman. Marathe further highlighted that automation solution

providers & users can have a mutually beneficial long term partnership, based on how these solutions are enabling better controls, better utilisation of assets and improving efficiency by connecting deep domain knowledge to automation technology advancements. “Pilot projects, for trying out the latest technologies, are the best way to gain the confidence of the user. By doing this, we can ensure a continuous engagement between users and automation suppliers,” said Nair.
Can intelligent self-controlling power generation become a reality? Speaking on self-controlling power, Marathe believes that power plants having single pushbutton start-up operations and advancement of control & instrumentation systems already exists. “However, this has still not reached the level of optimum controls and that’s where our company with advanced technology solutions can help power producers.” On the other hand, Ganpathiraman said, “Self-controlling power generation is unlikely to become a reality, because in a thermal power plant there are more than 20,000 major components and millions of other components to be connected on real time.” Moreover, in the fluctuating scenario of power supply, generators can adjust the active, reactive power to compensate power fluctuation. Highlighting this thought, Vuppala concluded that M2M devices and actuators coupled with analytics can make the intelligent self-controlling possible for the power generators. ☐ > MORE@CLICK ADI03612 | www.AandD24.in

In the beverage industry, a lot of glass is handled on a typical bottling line. Every hour up to 60,000 bottles are filled on each line. Numerous different sensors ensure that processes run smoothly. At the end of the production, the “full crate control” checks whether the crates are filled with the correct number of bottles. If a bottle is missing, the crate is rejected and the missing bottle added manually before the crate leaves the plant.
Fault sources Fortunately, it rarely happens that a bottle is missing in a crate. If this happens, the reason for this is often the bottle packer. With its pneumatic grippers, it takes the bottles from the sorting system and puts them in the empty crates. When doing so, it can happen that a bottle is not correctly gripped. Therefore, a full crate inspection unit is installed on the following conveyor belt. With an optical 3D sensor, it looks at the crates from the top to check them for missing bottles before they are palletised and delivered.
Conventional control for missing bottles Worldwide conventional bottling processes use diffuse reflection sensors arranged in a matrix to look at the caps of the bottles from the top. If a bottle is missing, no light is reflected back to the sensor. The sensor provides an error signal to the controller.
Control using a 3D sensor This installation uses the full crate inspection system from the OEM Recop. The heart of the system is efector pmd3d from ifm electronic. This sensor is a 3D camera with integrated evaluation. Its resolution is 64 x 48 pixels. For each of the 3,072 pixels, the sensor supplies a distance value which is
A&D India | Dec’ 14-Jan’ 15
Food & Beverage -Focus- ifm.indd 35
precise to the nearest millimetre, up to 25 times per second. It looks at the crate from the top. The distance between the bottle cap and the sensor is evaluated at defined positions in the camera image. If it is outside the set range, the sensor provides an error signal and the crate is rejected. One sensor alone can reliably detect several missing bottles.
Advantages of the 3D control Compared to the conventional crate monitoring using diffuse reflection sensors, efector pmd3d can find additional faults in the crate. Due to the distance measurement, which is precise to the nearest millimetre, it detects small differences in height. If, for example, broken pieces of glass are between the bottom of the crate and the bottle, the bottle would be slightly higher. This would be detected by the 3D sensor rejecting the crate. Photoelectric diffuse reflection sensors, however, would not detect this fault. In addition, the vision sensor can be easily set to different shapes of crates and bottles via software parameter setting. The reference image can be selected later by using a simple switch. This eliminates the need for a mechanical modification of the reading matrix as would be necessary for the diffuse reflection sensor method. This saves time and money when the plant is retrofitted. The surface characteristics of the bottle caps, e.g. silvery or matt dark print, which again and again lead to faults with the diffuse reflection sensor method, is not a problem for the 3D sensor. Since the 3D image is evaluated in the sensor, an external controller is not needed. The sensor’s switching output can trigger via a switching signal that crates with missing bottles are rejected.

These values enable the detailed assessment of the object’s or scene’s characteristics up to a range of 6.5 m with an unambiguous range up to 48 m. The evaluation unit is integrated into the device. The results can be transferred to the controller via two switching or analogue outputs and an Ethernet process interface. The parameters of the sensor are set via pushbuttons on the device or a PC software. The sensor has an Ethernet interface for parameter setting and communication.

Will the food industry crack under pressure? In recent years, manufacturers around the world have been under growing pressure to increase production with reduced costs. This article explains how food and beverage manufacturers can remain productive by balancing between increasing raw material prices, energy prices and pressure from retailers.

According to the 2013 food statistics pocketbook, food prices in the UK have risen in real terms by 12% since 2007. This price increase is emulated internationally and is partly associated with the increasing costs of raw materials and energy. It also reflects the pressure giant retailers have been exercising on food and beverage manufacturers to provide cheaper end products.
Between a rock and a hard place This situation leaves manufacturers stuck between a rock and a hard place since they need to comply with retailer demands and respond to particularly precarious customer preferences, while finding a way to reduce production expenses and not pass cost increases on to customers. In a recent industry survey, 83% of the food and beverage manufacturers that responded expressed concerns of pricing pressure from retailers were threatening the quality of ownlabel products. Around 74% further estimated that this pressure was threatening to cut into new product development budgets. As in any other industry, lack of research and development limits innovation, which in turn, reduces investment, growth and profit. While the food and beverage industry is one of the industries that will not suffer, its potential would be significantly limited should investment in innovation decreases.
How do you reduce costs? Moving manufacturing operations to a cheaper territory stopped being a viable solution long ago. Cheap labour isn’t strategic in the long run and most industries have already turned their backs on this option.
A&D India | Dec’14-Jan’15
Food & Beverage -Focus- European Automation.indd 39
Another way of protecting manufacturers’ interests would be to impose legal restrictions that ensure key obligations for retailers. One example would be guaranteeing that retailers give reasonable notice to change supply arrangements, that they deal fairly and lawfully and don’t constrain manufacturers to obtain goods, services or property from a preferred third party. When these codes exist, they are often limited by the free market and competition law, which means that reducing manufacturing costs needs to come from somewhere else.
Think ‘lean’ The fastest and most efficient way to reduce costs is by designing and managing a manufacturing process that results in the lowest possible unit cost. This means taking a good look at the operations and identifying how they can be improved. Today, production lines operate at less than 60%, which means there is considerable room for improvement. Identifying planned losses (cleaning, preventative maintenance or decreasing product demand), operational losses (changeovers, stoppages or shortages) and quality losses (scrap products or defective materials) is the first step in making manufacturing lean. The next step is utilising existing real-time data collection from the process equipment to improve Overall Equipment Effectiveness (OEE). Intelligent automation solutions help minimise process variability and maximise asset use and productive capacity.

Busting the myth
Manage breakdowns Breakdowns are inevitable, but the way they are managed, it can make or break a business. Lean manufacturing principles state that when a breakdown occurs, the first step is to try all the options that don’t incur additional costs. Whether it’s a simple case of “turn-it-of-and-on-again”, checking the system for blockages or performing an emergency maintenance, internal resources first should be used. If the breakdown is due to faulty equipment, it’s likely that manufacturers will be able to resolve the situation by getting the part repaired or just purchasing a spare industrial automation component.

One of the myths surrounding the food and beverage industry is that it’s an out-of-date and old fashioned sector, which doesn’t offer exciting professional prospects. The challenges and external pressures the food and beverage industry is faced with make the rhythm of innovation particularly swift. At European Automation we have definitely sensed a shift towards intelligent automation, reflected in the purchases our clients make. Our food and beverage clients have started purchasing newer generations of PLCs, HMIs, digital sensors and transmitters. This means that despite being under pressure, the food and beverage sectors is still a leader in innovation and has great potential for growth. ☐ > MORE@CLICK ADI03614 | www.AandD24.in

The four M’s of food manufacturing Improving operational efficiency in manufacturing is a vital element in the process of food & beverage production.To do this, it is important to consider the entire production-cycle spectrum, right from raw material receipt to finished goods. This article briefs on the four M’s essential in food manufacturing, while highlighting sustainability and line integration in the manufacturing process to acheive operational efficiency.
With high complexity and low margins, it often pays to take a simple approach to food & beverage production, to drill down to a few essentials and ensure that one is performing at optimum levels. While improving operational efficiencies, one should consider the entire production-cycle spectrum, from raw-material receipt to finished goods. At each point during production, there are four key areas that one will be required to evaluate while using the assets in the most productive way. These four categories are all intertwined, so increased efficiency in one area can impact the other three, just as waste in one category can cascade down the rest of the manufacturing process.

By implementing end-to-end quality assurance, one can both keep quality high and drive costs down by controlling wastage and process inefficiency. Standardisation helps to maintain consistency of product wherever manufacturing is carried out.

How might one make better use of your existing team’s skills, and what one needs to do now to legislate for the skills shortages currently facing the industry?

As per a survey conducted by Global Food Security, by 2050, the global population is estimated to reach 9 billion. “Along with the need to feed this growing population is awareness of the impact the necessary increases in production have on the environment. An increase in energy usage required to drive production, increased waste for landfills, and depleting natural resources will all result from higher, more concentrated population levels”, says David Lefebvre, Industry Sales Manager CPG - EMEA, Rockwell Automation In this scenario, manufacturers have the responsibility of balancing the need to meet increasing demand with operating safely and sustainably at the lowest possible cost. Most manufacturers are starting to track energy consumption in some capacity, whether at a site level or down to specific production lines. By monitoring consumption, these companies can make operational changes to reduce energy consumption & costs. Access to historical data also permits management personnel to address intermittent or persistent power-quality issues, such as voltage sags or harmonics. By doing so, they can save thousands of dollars in damaged equipment or poorquality product, and avoid penalties associated with powerfactor problems on the energy grid. This type of data monitoring and analysis is critical to make improvements. Though one cannot improve what cannot be measured, but OEMs also can help their customers look ahead to what’s next. Visible and actionable water, air, gas, electricity and steam data allows managers and operators to constantly see and resolve issues. It’s especially important to secure on-going gains because improved management of energy consumption won’t necessarily deliver substantial improvements immediately. Energy management is a marathon, rather than a sprint, with savings measured in hour-to-hour and day-to-day increments: When and why did a machine exceed typical energy draw? Why did an equipment changeover cause startup surges? Why did a component change extend the production cycle into a peak-draw period?

Visibility is the only practical way to keep track of progress. While behaviours relying on human observation and intervention – involving managers and team members that perform the activities of plan, do, check, and adjust; the key to accelerated energy-efficiency improvements lies within the streams of data running to, through and from equipment.
Line integration – time on your side How many times has one heard saying that there are simply aren’t enough hours in the day or time waits for no one. We all know what it feels like being up against the clock, but what if one could get time back on one’s side? We haven’t found a way of getting more hours into a day or having time stand still when we need it to, and despite many successful years of developing retro-encabulator technology, the Rockwell automation R&D department has not perfected a time machine. So, how can manufacturers get some time back? It is well understood in CPG that flexibility and agility are attributes of superior integration. Those at the forefront of line integration implementation for the CPG industry are getting new products to market in as little as half the time they were able to before integrating their lines and can be benefitting from a huge decrease in downtime attributed to cycle changes and unscheduled downtime due to failures. This also allows them to be more flexible and responsive to consumer demands for variant flavours, special editions, new packaging and all manner of product specifications. The sheer variety of functions required by packaging machines means that they have been supplied by a vast range of machine builders to perform their various functions; filling, case making, wrapping, labelling, palletising in various flavours of performance vs cost. While the increased adoption of machines onto the ISA-88 and packaging machine language PackML practices has improved the ease of integration, it has not solved the ever present level of disparity even when standards are applied. The game changer is in the use of public
44
Food & Beverage -Focus- rockwell.indd 44
interfaces that can completely normalise these disparities for a specific line integration solution. Now, rather than those machines needing customised integration work and extensive coding for all integration into new lines, the standardised format allow supervisory systems to monitor and control all of the machines regardless of the OEM or specific programmer, in a connected, configurable, and repeatable format. This opens up visibility of the throughput of the individual machines as well as a centralised view of how the overall line is performing. That saves the OEM or system integrator plant engineering, and management time. It also helps the end user to be more agile and responsive to consu mer needs, again, by being efficient with time. While good integration can be achieved without this type of machine interfacing, reducing the time, cost and variability of line startups and vertical integration is not fully realised without it. Having good line control and performance management capabilities working early in the line startup process has the biggest impact on the return time of capital investment. This, in turn, enables more continuous improvement and capital project investments to happen sooner. Manufacturing that relies on traditional integration where line control and performance monitoring are completely separate efforts live in the world of lost time. Without having these two capabilities tightly integrated, it is hard to know the root cause of problems in real time. A sophisticated report that is delivered well after the fact is too late. Again, timely information at the fingers of the operators running the line provides the best results. The longer these problems linger, the more the potential costs of spoiled or scrap product resulting from the failures. Many of the associated costs can be avoided with a system that can communicate to the operator where the failure is, as well as communicate directly to other machines in the process to react as needed, whether that is to slow, stop or to continue as normal in order to balance the line. ☐ > MORE@CLICK ADI03615 | www.AandD24.in

Facilitating process optimisation The article deals with computer tomograph (CT), a digital model analysed in 2D section and cut 3D view, to ensure measuring accuracy and comparability of the optical measurement Three-dimensional digital models of components can be created with the help of a computer tomograph (CT). The various materials of the component are represented in the digital model by different gray tones. This allows the different materials to be switched in or out of display, as desired. In addition, the digital model may be sectioned in any plane and subsequently analysed both in 2D section as well as in a cut 3D view. This can serve as a replacement for laborious manual grinding. By means of an analysis of foreign material within the component, the distribution of pores and voids may be visualised. This enables targeted process optimisation of injection moulding and high pressure die-casting processes. The digital model can be used to determine the surface of the component. The surface contour of the component allows its dimensions to be established. Digital cutting of the surface

contour yields contours similar to those from optical measurement of sections. An advantage of using CT for dimensioning is that the measurement programs for determining the dimensions can simply be reused. This is especially useful with highly reentrant tools. A further possible assessment method is the direct comparison of the actual surface contour with the data of the CAD model. Here, deviations are displayed with colour codes, simplifying the recognition of sunk areas and component distortion.

Then, the test object is rotated slightly and another radiograph is taken. This continues until the test object has completed one turn, where the number of radiographs may be set to reflect the desired accuracy.
All about the 3-dimensional digital model After the CT scan, a digital model of the test object is calculated from the individual radiographs. In the digital model, the dependency on the path length is eliminated and the different materials of the test object are represented by different gray tones. The accuracy of the model is a factor of the number of pixels in the detector and also the degree of magnification of the component. Since the component is placed between the X-ray source and the detector (Figure 1), its magnification increases with its closeness to the X-ray source. This magnification determines the size of a pixel of the digital model. Interpolation between the pixels allows accuracy of the model to be increased still further. With 3-dimensional models, the term voxel is used instead of pixel. The model contains a gray tone for each voxel, which depends on its material. For a test object consisting of only one material, there is, therefore, one gray value everywhere in the test object and another gray value, where there is air. This transition between air and test object allows the surface of the test object to be determined. The analysis of components takes

place on the digital model of the test object. Here, different materials can be displayed or hidden, and digital sections can be performed in any plane. The model can be displayed either in a 3D or 2D section. As a part of the final checks before release, the contact overlap is checked to ensure the reliability of the connection. This is conventionally performed by making sections. A section must be made to check the overlap of the power contacts. In addition, the deflection of the RJ 45 connector in the various levels of its spring must be checked. Thus, computer tomography allows a considerable simplification of this procedure. The connector is connected up and scanned, and a digital model of it is produced. Cavities and material defects exhibit different X-ray absorption characteristics than the solid material. This allows cavities and defects to be found by the use of CT analysis of components. These can be then displayed in the digital model or colour coded to reflect their size. A cavity analysis can be performed for both plastic and metal components. The company has used this possibility for optimising process parameters with regard to the size, number and distribution of cavities.
Determining the dimensions of components The surface contour may be extracted from the digital model of the test object. This can be used to determine the dimensions of the component. Sections can be placed through the contour, so that dimensioning of a section is possible, analogously to conventional dimensioning. Geometrical elements can be defined in the sectional view, allowing the

dimensions corresponding to the drawing to be determined. The definition of the dimensions proceeds manually by the writing of a measurement program. However, several advantages result in comparison with conventional dimensioning. Here, sections must be made laboriously and there is the danger of distortion caused by grinding the test object. With CT dimensioning, any number of digital sections can be produced without additional effort. This allows, for example, the shape of a chamber in the vertical direction to be examined by sections at different heights. So, it is only necessary to define the measurement program in a plane. Subsequently, the location of the sectional plane can be shifted in a loop. In addition, the measurement program need only be created once, and can be reused simply by replacing the contour. This is especially useful for the dimensioning of components with several cavities.
Calibration accuracy The calibration accuracy of the computer tomograph is determined with a pin array and a cube containing spherical caps. To ensure measuring accuracy and comparability of the optical measurement with CT dimensioning, in addition to the calibration of CT with the standard calibration jigs, investigations on HARTING components have been conducted. For instance, a chamber in a male connector was measured optically and with the CT. The optical dimensioning was performed with a plan view, and was carried out several times by several users in order to minimise the influence of the user. For CT dimensioning, the component was scanned several times and was then performed in a defined sectional plane. While comparing the measurement results, different measurement strategies must be taken into account. With the optical measurement in plan view, a minimal dimension of the chamber breadth is read, since it is always the corresponding outermost contour which appears as the edge. With the CT,
50
Technology Industrial Computers & Peripheries HARTING.indd 50
the measurement is determined exactly in a sectional plane. This can be freely defined, which similarly allows the minimal dimension of the chamber width to be determined. Then the optical and the CT measurement results are in good agreement.
Optimised measurement procedure Since measurement programs, once written, can easily be reused, the possibility of an optimised measurement procedure arises. When the CAD model of a new component is produced, it is used to produce the corresponding tool. But this model can also serve in parallel as the basis for producing the measurement program, using the surface contour defined in the model. When the first samples fall out of the tool, these will be scanned in and the artificial surface contour based on the CAD model will be replaced with the actual surface contour of the sample. Using the previously produced measurement program, the dimensions can then be obtained automatically.
False colour comparison In addition to the determination of individual measurements, deviations between two contours can also be represented through false color comparison. Here, the deviations between the contours are indicated with colours. On the one hand, this allows a comparison between a real contour and a CAD contour. This enables a good overall impression of a component, which goes beyond the comparison of dimensions. For instance, this allows easy recognition of the distortion of a component or the sinking of individual contours. Besides, two real contours can be compared with one another. In this way, the condition of a tool can be monitored or individual cavities can be compared with one another. â&#x2DC;? > MORE@CLICK ADI03616 | www.AandD24.in

Adopting high efficiency motors Motors are the workhorses of manufacturing industry offering large potential for energy cost reductions. This article deals with the significance of energy conservation by adoption of energy efficient motors across industries and benefits derived by the users and the environment. Renewable energy and energy efficiency are said to be the “twin pillars” of sustainable energy policy. Both resources must be developed in order to stabilise and reduce carbon dioxide emissions. Sustainable energy apart from other renewable energy focuses on the ability of an energy source to continue to provide energy is distinct from low-carbon energy, which is sustainable only in the sense that it does not add to the CO2 in the atmosphere. Moving towards energy sustainability requires changes not

only in the way energy is supplied, but in the way it is used, and reducing the amount of energy required to deliver various goods or services is essential. Efficiency slows down energy demand growth so that rising clean energy supplies can make deep cuts in fossil fuel use. Opportunities for improvement on the demand side of the energy equation are as rich and diverse as those on the supply side, and often offer significant economic benefits. The solution is to find sustainable energy sources and more efficient means of converting and utilising

energy. There is significant energy conservation potential by adoption of energy efficient motors in the industries. Motors and motor driven systems are huge consumers of electricity, they are estimated to account for 43%-46% of all global electricity consumption as well as 69% of all electricity used by industry.
Electrical motor efficiency Inefficient electric motors waste electrical energy. Since most electricity is generated from fossil-fueled power plants, motors and motor-driven systems are indirect contributors to greenhouse gases produced by these plants. Hence, there are compelling economic and environmental reasons to increase the use of energy efficient motors. This is a problem for several reasons like inefficient electric motors waste electrical energy, thereby increasing electrical demand and associated electricity costs required to power motors. When electricity is generated by oil- or coal-fed power plants, the burning of fossil fuels produces carbon footprints from the usage of natural resources and emissions of greenhouse gases. Electrical energy losses from inefficient motors, therefore, waste precious natural resources, cause increased emissions of greenhouse gases, and increase operating costs (i.e. increases utility bills).
Increasing electrical energy efficiencies of motors There are compelling economic and environmental needs to evaluate the benefits of energy efficient and premium efficiency electric motors versus their standard counterparts. A well-designed motor can convert over 90% of its input energy into useful power for decades. When the efficiency of a motor is raised by even a few percentage points, the savings, in kilowatt hours (and therefore in cost), are enormous. For example, it has been estimated that if all countries adopted best Minimum Energy Performance Standards (MEPS) for industrial electric motors, by 2030 approximately 322 terawatthours of annual electricity demand would be saved. The electrical energy efficiency of a typical industrial induction motor can be improved by reducing the electrical losses in the stator windings (e.g. by increasing the crosssectional area of the conductor, improving the winding
54
Tech Motors & Drives- ICAI.indd 54
technique, and using materials with higher electrical conductivities). Reducing the electrical losses in the rotor coil or casting (e.g. by using materials with higher electrical conductivities), decreasing magnetic losses by using better quality magnetic steel, improving the aerodynamics of motors to reduce mechanical wind age losses and minimising manufacturing tolerances. In addition to energy savings, other benefits of high efficiency motors over standard motors include cooler operating temperatures due to lower heat generation, which results in lower maintenance and a longer life; improved tolerance to voltage variations and harmonics; extended manufacturersâ&#x20AC;&#x2122; warranties and rebates & tax incentives in some regions from utilities and municipalities.
Tools to evaluate motor efficiencies and lifetime costs As part of its initiative to enhance the efficiency of motors, Motor Energy Saving Calculator, a free tool can help calculate approximate annual savings in choosing IE2 & IE3 versus a lower efficiency model. Older operating motors with low efficiencies can also be evaluated for replacement. These motors cannot be rewound to exceed their original electrical efficiency design standards.
Induction motors Motors have evolved into a variety of types according to user requirements, design, and production costs. This section will address copper in energy-efficient alternating current (AC) induction motors because these motors are widely used in industrial drives. The main parts of an AC induction motor are the fixed housing body (stator), a rotating assembly (rotor) and electromagnets consisting of coils of copper or aluminium wire around a core of magnetic steel. Copper and aluminium can both be used in the stator coils, although copper coils are the standard as they are more flexible and they enhance motor electrical efficiencies due to their higher electrical conductivity. Aluminium die-cast rotors are the standard material but copper die-casting of rotors is an improved new technology that is increasingly used to enhance motor energy efficiency.

Based on CEMEP, efficiency levels eff2 (improved The electrical efficiency of motors can be improved by efficiency) and eff1 (high efficiency) had been defined. Apart replacing the standard aluminium electrical conductor in the from the efficiency class, this standard also specifies other rotor with copper, which has a much higher electrical performance parameters like breakaway torque, breakaway conductivity. Until recently, die-cast motor rotors were current, minimum speed, maximum full load current, etc, for produced only from aluminium while researchers worked on each of the ratings. In other words, this outlines performance solving technological issues with copper pressure die-casting. specifications for energy efficient motors. Today, copper pressure die-casting is a proven technology and The Bureau of Energy Efficiency also launched its voluntary thousands of die-cast copper motor rotors are produced labelling plan in 2007 based on standard IS 12615:2004.

The main features of the revised standard are: The ranges covered are from 0.37 kW to 375 kW for 2, 4 and 6 poles Intermediate ratings are considered based on the Indian markets. The efficiency classes are in line with IEC 60034-30 termed as IE2 and IE3 The testing method specified is as per IEC 60034-2-1. Checking and building capacity is the major task in implementation. The other performance parameters like starting torque and starting current are considered and specified for all three levels (IE2 and IE3)
Way forward The standard making body, BIS and the regulatory body BEE have been working towards bringing the supply chain, end users and other stakeholders together to harmonise Indian standards with IEC taking into account the Indian market needs and conditions. The effort of harmonisation of motor standards globally and the regulations introduced in different countries have been a trigger to move in a positive direction. On publishing the new motor standard, BIS and BEE are planning to draw a realistic but firm timeline to introduce minimum Efficiency Performance Standards of IE3. The following barriers that need to be addressed for smooth implementation of these policies are: • Capacity building of small and medium scale motor manufacturers to manufacture high and premium efficiency motors • Adequate test facility establishment as per prescribed testing standards. • Awareness creation among end users regarding life cycle cost • Establishment of incentive mechanisms for adopting high and premium efficiency motors and penalties in case of deviations

Premium efficiency design have an effect on other performance parameters like stating current, starting torque, slip etc, and the barriers from the markets to accept these parameters is important Integrate motor driven systems into the process so that the original equipment manufacturers also appreciate benefits of premium efficiencies. In India, the comparative star labeling of pump sets is the best example in this direction.
Conclusion Motors are the workhorses of manufacturing industry offering large potential for energy cost reductions. Traditionally, capital equipment purchases are based on lowest first cost principles and motor selection is no exception. This needs to change to life-cycle costing based purchase. Purchase specifications for motors need to include efficiency in addition to basic parameters like KW and RPM. Apart from energy savings, EE Motors have a superior built and provide intangible benefits and a longer life. The penetration of high efficiency motors and premium efficiency motors is low in India. Efforts are being made to address existing barriers. These efforts include regulatory measures, standards making and harmonising Indian standards with global trends. In spite of the regulatory measures and the supply side involvement, it is required to address the end users so as to create a pull for high efficiency motors. BIS and BEE have been working with all the stakeholders to implement this standard (IS 12615:2011) by addressing the barriers and planning a way forward to move towards premium efficiencies in the next 2 to 3 years and compete in the global market. This combined effort of all the stakeholders will ensure that the goal is achieved. Although there are several barriers, the adoption of energy efficient motors can give immense benefits to the user as well as the country and environment. ☐ > MORE@CLICK ADI03617 | www.AandD24.in

Tracing the right mark The article highlights the top considerations for implementing a Direct Part Mark (DPM) traceability process onto a fully automatic manufacturing line with fixed-mount code readers Part tracking or traceability is vital for those that make, store or move items through supply chain because the data is used in production output calculations, inventory control, revenue forecasting and other business operations. Traceability also improves quality by ensuring that the appropriate processes are performed in the correct sequence on the right parts. To track a part through its full lifecycle, manufacturers mark it with a permanent two-dimensional (2-D) code known as a Direct Part Mark (DPM). These codes are used due to their small size, error correction and amount of data that can be stored as compared to traditional 1-D barcodes. They also help with anti-counterfeiting measures as they are more difficult to replicate. Automated image-based ID readers are the only technology capable of decoding such marks as laser scanners are only able to read 1-D linear barcodes. Automatic identification technology eliminates any need to manually enter data during

production, avoiding human error and increasing efficiency. On fully automatic manufacturing lines, parts are handled and moved by conveyor, indexer or robot and the ID reader is mounted in a fixed position where the mark can repeatably be placed in front of the reader. Similarly, a presentation reader operates in a continuous reading cycle, automatically performing the decoding task once the operator places the part in front of the reader. This guide highlights the top considerations for implementing a DPM traceability process onto a fully automatic manufacturing line with fixed-mount code readers.

If the bumps on the surface of a cast part are similar in size and/or shape to the dot peen marks of the code, readability suffers because the code blends in with the bumps in the surrounding image
as do the Air Transport Association (ATA), the US Department of Defense (DoD), GS1, SEMI and others. When specified, it generally makes sense to follow the industry guidelines because it improves efficiencies throughout product manufacturing and the supply chain. However, if no guidelines are available within the industry, one can use an existing guideline to create their own, noting that Data Matrix ECC200 is strongly recommended and is clearly becoming the choice for most industries involving metal, glass, ceramic or plastic materials. It is very flexible as it offers 24 square formats and six rectangular formats to encode anywhere between six and 3,116 digits in a single code. It also supports Reed Solomon error correction that allows a code to be successfully decoded even though as much as 60% of the code may be damaged. Since this code is in the public domain, marking and reading equipment suppliers have invested significant R&D resources to improve the performance of supporting equipment.
Marking processes & placement
surface to melt, vapourise or change in some way in order to produce a mark. The resulting quality of the mark depends upon the interaction of the laser with the material it is marking. It is most often used in the semiconductor, electronics and medical device industries. Electro-chemical etching (ECE): It is a process whereby a mark is produced from the oxidation of metal from the surface being marked through a stencil impression. ECE is a timeconsuming process and has a high cost for on-going consumables. It is used for low volume marking of round surfaces or for stress-sensitive parts of jet engines, automobiles and medical devices. Inkjet printers: It precisely propels ink drops to the part surface creating a permanent pattern of modules. It may require preparation of the part surface, as it is the chemical interaction of the ink to the surface of the part that determines the level of mark permanence and contrast. It provides fast marking of moving parts and offers very good contrast. The location of the code on a part can directly impact the readability of the code. It should be clearly visible throughout the manufacturing process and, wherever possible, it should provide a “clear zone” free of part features and edges, noise/ texture or other interference. Parts that present some of the most difficult reading situations include cylindrical or shiny parts that can create code distortion and specular reflection.
The 2-D DPM codes are marked on the part using several methods depending upon material composition, part application and environmental conditions. Important factors influencing the marking process decision include part life expectancy, material composition, environmental wear & tear and production volume. Dot Peening: It is achieved by striking a carbide or diamond Data encoding & readability tipped stylus against the surface of the material being marked.

can affect readability. Readability defines how easy or difficult it is for a reader to successfully read a code. If a code is not readable, the part is not processed and/or the production line stops. Manufacturers live with varying read rates but should strive to achieve six sigma read rates which equates to only 3.4 defects per one million reads. One factor that contributes significantly to overall readability is the quality of the mark. The process of inspecting the quality of a mark is known as verification. The verification process is defined within the industryâ&#x20AC;&#x2122;s guidelines and generally takes place offline. Besides mark quality, one must consider other factors that can affect overall read rates. Successful location of the code within the field of view is the first step in successful reading. The next step is for the reader to determine which modules are light and which modules are dark. A code pattern with modules that are consistent in shape and size, but distinctively different from other features on the surface of the part provide the most reliable decoding. However, because of the very nature of DPM applications, this can be challenging due to variations in the surface texture, part presentation during the process, variability of the marking machines and changes that the parts undergo throughout their lifecycle.
Selecting a solution There are three categories to review during the evaluation process to ensure the highest read rates possible: decoding software, image formation and ease of use. Decoding software: Code reading algorithms form the basis
64

for any image-based ID reader. There are many variables that impact the readability of the code like distortion due to part material composition and variations in part presentation or variability caused by the manufacturing process. Powerful algorithms can read codes marked on any surface with any form of degradation. One can test a solution with as many sample parts and variations that one can imagine. But even the most advanced algorithms can perform better and faster with the help of resolution, lighting and optics. Image formation: A reading solution should tolerate changes in contrast, focus and degradation to the code without a need to change the underlying parameter settings. One should test the setup by adjusting the aperture or exposure to simulate change in contrast, focus to simulate change in depth of field and position of the light to simulate background problems. When determining the resolution requirements, the most important thing to consider is the number of pixels per module (PPM) one will need within your field of view. Higher resolution readers can maintain a high PPM for a larger field of view, allowing for more positional uncertainty. For very high speed applications, a standard resolution reader will generally provide faster performance. Some high resolution imagers, however, allow the application to use only part of the imager, which can create even faster response times. Lighting is especially important for DPM applications involving metals or other difficult-to-read materials. The proper lighting technique for dot peen applications, for example, can make or break a process. These marks are difficult to read unless lighting adjustments can be made.

with controllable lighting is a key for this application. A reader that allows the user to change the lens offers greater adaptability for the reader to be deployed for different working distances based on the machine design requirements. Very often, the machine is designed long before a reader is considered, so having flexible optics in the reader makes retrofitting easier. Ease to use: When readers are deployed, different parameters are set up to optimise the application. A step-by-step process should be intuitive for any floor personnel. In addition, the reader must be able to communicate the results to another device, easily integrating into existing plant networks through whatever communications method is required: Ethernet, RS232, etc. For establishing a communications link between a reader and a PC at the enterprise level, one has to make sure that the reader supports a broad range of standard network protocols, including: EtherNet/IP, PROFINET, MC Protocol and Modbus/TCP. This connection also gives you a centralised way of managing the readers. Thus, the ID reader selected will allow managing and controlling activity over the network from

remote locations in the plant and beyond. Having an easy to use setup tool minimises the time it takes to integrate the reader and reduces the overall maintenance effort of the system.
Conclusion DPM reading can be a very challenging application requiring technology and expertise solving difficult image analysis problems. Typically, companies experienced in industrial machine vision have the right expertise and technology for providing the highest DPM read rates. The chosen vendor should also be able to provide the support necessary to thoroughly qualify the application, guide one through to installation success and have the financial stability to maintain their role as your DPM reading solutions provider for the long term. â&#x2DC;?

Safety Lifecycle Management An application story on how Advanced Integration Technology (AIT)—an aerospace automation provider has incorporated safety PLCs, motion control, safety and standard I/O on a single PROFINET network for more efficient & compliant automation. Integrating control and safety requires a holistic safety mindset built around Safety Lifecycle Management, as specified by major safety standards such as IEC 61508, IEC 62061 and ISO 13849. This is a systematic, phased approach to safety with steps that are well documented and verified, from initial hazard and risk analysis to safety system implementation all the way through to system decommissioning.
Integrating safety The steps of integrating safety include: and engineering, including risk assessments & identification, and definition of safety functions needed for a safe manufacturing process; Installation and commissioning, including testing of safety functions and training personnel in for safety; Operation and servicing, including access to documentation and spare parts for keeping machines functioning safely, periodically testing of operations and fast diagnosis of faults; Maintenance, including the inspection and regular

replacement of safety-relevant components; and upgrading, including the implementation of functional safety advancements as a machine’s safety design and engineering allows. Following these steps, Advanced Integration Technology (AIT), a 20-year-old supplier of turnkey industrial automation systems for the leading aerospace suppliers, made major strides in machine safety. As a prime contractor on the Boeing 787 Dreamliner, AIT had responsibility for the final assembly and body join functions, charged with delivering a fully automated positioning and joining system. A comprehensive safety scheme with Safety PLCs is a central element in the system, which communicate using PROFINET. To help plant operators and safety engineers comply with the requirements of IEC 62061 and ISO 13849-1 standards, a TÜV certified online Safety Evaluation Tool (SET) was also available.

of the fuselage are joined using 14 positioners mounted to transport structures that move either independently or interlocked and indexed to the factory floor for stability. Realtime positioning measurement data are logged with an integrated indoor GPS. AIT designed the alignment and positioning systems that roll under the aircraft dollies, radically reducing auxiliary equipment needs, materials handling requirements, and additional positioning steps. Onsite at Boeing, the 14 positioning system components were moved into their respective locations near the cradle dollies. Once the system is rigidly joined, a measurement system onboard locates the airplane sections. This information is fed to the system’s software application. From those data points, the system calculates how much each section (nose, tail, left and right wings) needed to move to ensure an exact fit to the adjoining section. This precise alignment ensures a smooth, rapid build of each fuselage. Siemens was tapped to provide equipment for AIT. “We looked for a supplier with an off-theshelf selection of automation and motion control solutions, who could offer us global support,” says Ed Chalupa, President, AIT. “Our goal was to utilise all current software, integrated safety, and control technology advancements. Both Boeing and AIT were keenly sensitive to lifecycle security issues in this critical area of the project.”
selections, the final body-join assembly tool runs as a single entity. Running together in this configuration, the safety devices work coherently, providing proper response levels to all Emergency-stop situations. Each unit motion controller receives commands to perform uniform group movements with the tool as a whole via network communications from the HMI. The integrated safety concept on this overall system is based on three core principles: increasingly layered safety architectures, greater degrees of integration between the control and safety systems, plus more use of networking, especially PROFINET. In operation, these safety principles manifest themselves in the form of physical barriers and mechanical means such as walls, gates, door interlocks, and more. They all isolate personnel from danger. Meanwhile, the control systems including safety PLCs monitor operating conditions within established parameters. The final protections are safety shutdown systems such as automatic shutdown via PROFIsafe-enabled safety PLC and manual shutdown via E-stops.
Conclusion
With integrated safety and control, the project has a single system for standard and safe automation. Having one PROFINET network and one engineering system for both standard and safety technology, further reduces cost. As a collateral benefit, the software solutions allow easier replication Employing PROFINET of series machines.

Fieldbus station for control cabinets
Micro-Epsilon has offered the mainSENSOR MDS-40-MK and LP series of sensors — a new generation of cost-effective and flexible magnetoinductive sensors. Four MDS-40-MK series predefined sensor variants are available with different connector, power supply and output options. These parameters, including the protection class, can be individually configured to suit the customer’s specification for series production of 200 pieces or more. Regardless of the order quantity, the mainSENSOR MDS-40-MK printed circuit board of the MDS-40-LP sensors can be adapted to suit the individual application and to other customer requirements. With both series, the measuring ranges can be defined by selecting the corresponding magnet type for the respective target and measuring arrangement. The sensor is based on an innovative measuring principle, which has been developed to combine the advantages of both inductive and magnetic sensors. As different strength magnets are applied, measuring ranges of up to 55 mm can be achieved.
MurrElektronik's Cube20S is a compact, efficient fieldbus station for control cabinets. The new modules also feature modular designs - a characteristic for these products. Cube20S connects slim input and output modules with a width of only 12.5 mm for base modules with integrated bus nodes. Digital and analog modules with two, four or Cube20S eight channels are available, as well as function modules like counters or potential distributors. Combining the standard output modules with safety MIRO Safe+ make it possible to safely switch off non-safe outputs up to category 3 PLd. Modules for active safety applications up to SIL3 and PLe are also planned. The fieldbus stations can be precisely configured according to the engineers’ need for their installations. It is available for the fieldbus systems Profibus, DeviceNet, CANopen, Profinet, Ethernet IP, Ethercat, and Modbus. This wide variety of models and the short response times (up to 20 μs) make Cube20S suitable for a large number of applications.

Wireless sensor development kit Analog Devices has introduced a suite of comprehensive development kits enabling manufacturers of industrial equipment to easily add remote sensing and monitoring capabilities to their Internet of Things and Big Data products via a scalable wireless network. The wireless sensor development kits significantly reduce the time and effort required to move designs from proof-of-concept to production release. The out-of-the-box kits allow engineers to establish a working wireless sensor system in 15 minutes to report and Comprehensive development kits analyse remotely various types of sensor data, such as temperature, humidity and motion/ vibration. Along with two multi-sensor-node boards, the demo kits include a base station connector, an emulator platform, and a full-featured software package that includes a robust communications protocol stack and rich graphical user interface. The bill-of-materials for the multi-sensor boards is comprised of an integrated RF transceiver and ARM Cortex M3 microcontroller (ADuCRF101) as well as multiple sensor elements that include the industry’s lowest power triple-axis accelerometer (ADXL362).
Detection scanners for field monitoring applications Pepperl+Fuchs’ powerful Pulse Ranging Technology (PRT), the R2000 detection scanner is the ideal solution for demanding field monitoring applications and assistance systems. Empty bay detection and gap recognition are as easily accomplished as the detection of overhanging and interfering products in high-speed AS/RS applications. Assistance systems for collision avoidance in both automatic guided vehicles or manually controlled forklifts and tuggers are another class of applications where the PRT-enabled R2000 detection offers outstanding features and performance. The speed and performance of the scanner is due to the revolutionary PRT measurement principle, a true R2000 detection scanner time-of-flight technology based on ultra-short, high-intensity light pulses. The scanner offers exceptional ambient light immunity and unparalleled precision, even at long distances. Together with all products in the R2000 family it uses a unique rotating measurement head instead of an complex rotating mirror design. This approach provides several important functional enhancements including a wobble-free scan plane and a 360o field of view.

Configurable control systems
Compact mechatronic rotary module for flexible rotations
Pilz has recently introduced PNOZmulti configurator — configurable control systems that bridge the gap between classic safety relays and programmable control systems. The configurator guides the programmer step-by-step. First of all, the user selects the hardware he needs for his machine via “drag & drop”. This consists of a base unit and, if necessary, expansion modules with safe inputs and outputs, the number of which is displayed in table form. The integrated feasibility check stops the user selecting expansion modules incorrectly: only the PNOZmulti configurator modules supported by the inserted base unit are made available for selection. The PNOZmulti configurator provides assistance if the permitted number of expansion modules is exceeded or if modules are positioned incorrectly. Online help is always available during configuration. The configurator downloads the entire safety program on to a chip card. The chip card does not necessarily have to be inserted in a base unit. The program can also be copied via an external read/write device.
SCHUNK’s ERS rotary modules are developed for rotary movements in the medium load range. The compact mechatronic rotary module is available in unit size 170 with a height of 66 mm, achieving a nominal moment of 5 Nm, and a maximum moment of up to 17 Nm. It is used for implementing flexible and compact system concepts. The core piece is a torque motor with a hollow shaft. It is light-weight and compact, and is absolutely wear-free, making it ERS rotary modules very reliable. It can endlessly turn up to 250 rpm to any intermediate position at a repeat accuracy of 0.01°. In contrast to rotary modules with a conventional servo motor, the ERS has no additional interfering contours and no elasticity. In order to feed compressed air or signals without hoses or cables through the module, the compact module is available in a version with pneumatic-electric feed-through, by using a slip ring or air channel of up to eight electric signals (24 V DC / 2 A), and a fluid with a pressure of up to 8 bar.
