As the recession continues to take its toll on the global economy, demands for goods and services have dropped with it. Plane tickets have plunged, along with the number of travelers. Recent events like the spreading of the H1N1 influenza virus and the political uncertainty in Thailand have compounded the problem further. News of trade shows being postponed and even canceled provide reason for industry members to stay in their offices. However, it is not all doom and gloom in the travel industry and aerospace in particular. Singapore hosted the inaugural Aerospace Supplier eXchange (pg 61) in late May, bringing together local suppliers and key procurement decision makers in the industry. Described as a The ‘speed dating process’, the event was by all accounts a successful one and re-enforced the notion that the future of the aerospace industry is in Asia. Adding more weight to this argument is in Asia is a report on The Infoshop, an online market research portal. It forecasts that before 2028, China will buy more than 3,700 airplanes with the potential market value of US$390 billion, rising to the top of the civil aerospace market chart. Providing an alternative to air travel are high-speed trains (pg 64). Extensive railway systems are already commonplace in Asian countries like China, South Korea and Singapore and are set to expand further, providing a welcome injection of economic movement in the connecting engineering sectors. Nobody knows for certain when it will happen but the recovery of the economy is inevitable and like commuters on the Shinkansen (Japanese bullet train) or travelers on a first class flight, you should buckle up and enjoy the ride.

Industry News Breakthrough In Solar Power Generation
Canberra, Australia: Researchers at the Australian National University in Canberra have developed technology that makes large scale solar thermal power generation commercially viable. The university has been involved in solar thermal power research for decades and is now conducting the final testing of its second generation ‘Big Dish’ solar thermal concentrator. The device has been built in the university grounds 8 industrial automation asia | June/July 2009
with support from corporate partner Wizard Power. To work efficiently, the mirrorcovered dish needs to rotate and change angle during the day as the sun changes position, and for that, a small control system is needed. Yokogawa successfully presented the case for its FA-M3 programmable controller, and won the order. The dish concentrates the sun’s rays
onto a receiver mounted at its focal point, providing sufficient heat to split ammonia into hydrogen and nitrogen gases. These gases can be stored indefinitely at ambient temperature until required for use. When power is needed, the gases are recombined in an exothermic reaction, which produces enough heat to generate electricity through a steam turbine. Because the Big Dish technology stores energy before generating electricity, it is capable of delivering multi-megawatt base load electricity and meeting peak loads on demand 24 hours a day in the same way that coal, nuclear or gas fired power stations do. It’s emission-free power generation on a large scale. Once the technology has been fully tested, it will be utilised in a pilot base load solar thermal power plant in Whyalla, South Australia to be built by Australian company Wizard Power. The Whyalla plant will initially have four dishes, each of which will have its own control system and be capable of producing up to 100kW of electricity. The Federal Government has supported the project with a A$7 million (US$5.4 million) grant, as part of its efforts to tackle climate change. Wizard Power is already engaged in negotiations to build more power plants around the world that could see coal-fired electricity generation eventually replaced with zero emission solar thermal power. There is also interest in the technology because the high temperatures that the Big Dish can achieve – up to 1200 degrees Celsius – make an array of other conversion opportunities possible. These include solar gasification of coal and biomass to produce distillates that can be used as clean transport fuels. “It’s very exciting for everyone at Yokogawa that our equipment is contributing to a technology that will have such a positive impact on the planet,” Yokogawa Australia’s MD, John Hewitt said.

London, England: In the most pessimistic of three ABI Research forecast scenarios, worldwide capital expenditure (CAPEX) on wireless infrastructure should still post a year-over-year growth of 1.5 percent between 2009 and the end of 2010. The most optimistic of the three forecasts sees that CAPEX figure reach as much as 3.7 percent growth. “It’s no surprise that 2009 will be a bad year for wireless infrastructure spending,” says senior analyst Aditya Kaul. “But 2010 is likely to see a renewed focus on spending due to competitive pressures around improving capacity and coverage.” Even within the depressed 2009 spending picture, regional differences exist. While spending has been reduced in Western Europe, operators in North America – despite seeing some negative impact – intend to continue with their 4G upgrade plans, while CAPEX in China and India is expected to get a boost as 3G deployments get under way. And, Mr Kaul notes: “The storm-clouds of 2009 may actually have silver linings. Some segments may benefit as alternatives to traditional macro base-station deployments: in-building wireless, femtocells, more energy-efficient ‘green’ base stations, infrastructure sharing, single RAN base stations, and more spectrally-efficient technologies.”

Spherical Roller Bearings Selected For Retractable Roof At Wimbledon
United Kingdom: More than 300 spherical roller bearings from Schaeffler UK are supporting a retractable roof over the Centre Court, Wimbledon. The roof is designed to open and close in less than 10 minutes and will be unveiled for the first time at the Wimbledon Tennis Championships in June 2009. The roof will enable a consistent and safe (non-slippery) playing surface to be maintained in both open and closed positions. The translucent roof allows a high percentage of natural light to reach the grass when in the closed position and
offers protection to the grass under all adverse weather conditions. The roof itself is of a ‘folding fabric concertina’ design, enabling it to be folded into a highly compressed area when not in use over the court. The roof is translucent enough to provide an ‘open’ feel even when the roof is closed. The fabric, 5,200 sq m of it in total, is a specially developed waterproof structural material that is extremely strong, and also highly flexible. The retractable roof is divided into two sections, with a total of nine bays of
structural fabric – four bays in one section and five in the other. Each of the nine bays of fabric is clamped on either side by prismatic steel trusses. There are 10 trusses in total that span approximately 77 m across the court. The ends of each truss are supported by a set of wheels that move along a track positioned on each side of Centre Court. At the end of the trusses, lie components that look rather like e n o r m o u s h i n g e s . S c h a e ff l e r ’s FAG spherical roller bearings are incorporated into these hinges. These bearings were selected for their low frictional resistance and ability to accommodate large misalignments. The bearings are lubricated with high performance grease and will require minimal maintenance during their service life. In total, Schaeffler supplied more than 300 bearings for the project.

Samsung Heavy Industries Advances Into Wind Power South Korea: Samsung Heavy Industries (SHI) has entered into the US wind power generator market, which it achieved by concluding an LOI with Cielo, a US-based firm, for the installation of three 2.5 MW wind power generators by 2011 in Texas. Launching the business in 2008, SHI has developed the wind power generator in cooperation with a UK engineering firm, which it unveiled at Wind Power 2009 in early May this year. As the US government has announced its intention to increase the portion of wind-generated power from its current level of one percent to over 20 percent of the power used in the US by 2030, the company decided to advance into the US market, recognising its high growth potential. These efforts have now borne fruit, with the company signalling its US market entry just nine months after launching the business. 14 industrial automation asia | June/July 2009
The 2.5 MW wind power generator developed by the company has a 10 percent higher power generation efficiency, a lifecycle of 25 years, which is five years longer than existing products. In addition, the company unveiled its mid-term targets, which include investments of KRW 600 billion (US$481 million), annual production of 200 units of 2.5 MW inland power generators and 5 MW offshore power generators by 2010, revenues of KRW 3 trillion through the production of 800 units of wind power generators in 2015, and the world’s seventh largest market share (10 percent). The company aims to operate in the US, Chinese and Indian markets with large territories through its 2.5 MW in-land wind power generators in the initial stage, and then increase its Asian and EU market shares with offshore generators that boast high efficiency and lower noise from 2015.

Toyota Honours Siemens For IWLAN Munich, Germany: Siemens has received the Toyota Technology and Development Award. The Japanese automaker presented the award in recognition of the improvements in productivity realised through the use of wireless control units from Siemens. The industrial WLAN system (IWLAN) makes it possible to operate robots at various stations of a production line much more quickly and with big gains in flexibility and efficiency. Thanks to the IWLAN systems, up to eight robots can be activated by means of a single mobile IWLAN device. Employees are also spared the time-consuming task of rolling up and rolling out the cable connecting the robots with the control
panel, which can be as much as 30 m long. Based on the WLAN wireless radio standard, IWLAN makes it possible to control factory machines by means of radio signals. To meet the special requirements of industrial applications, WLAN needs a few supplemental features, including dedicated data rates or high-speed roaming for time-critical commands — known as the iFeatures. The latest development in the IWLAN portfolio is a decentralised station and the iHOP function, which ensure reliable communication in spontaneous networks,

ith technological advancements and the rise of a new generation of high dynamic robots, successful i n t e g r a t i o n o f p ro d u c t i o n processes has the potential to yield greater efficiency and productivity. Failure to ensure appropriate safety measures within the production process, however, can pose significant risks with costly ramifications.

factors that must be taken into consideration. The first, and most obvious, relates to physical safety – ensuring the health and well-being of humans working alongside the line, as well as the protection of the actual equipment employed. The second factor addresses the production process itself – ensuring reliability within the

process to reach a production end-goal of 100 percent capacity. This article addresses the prerequisites for process safety at the employment of tool exchange systems on robots to safeguard that the utilisation of tool changers does not threaten the welfare of the workers on the factory floor or adversely affect the total output of the production line.
Conditions For Safety What prerequisites will prevent utilisation of tool changers from becoming an additional safety hazard? Consider the ramifications of the wrong command executed in a robot cell within the robot control, whereby the robot in motion receives the order to drop a 200 kg welding gun. In these instances, where high dynamic robots are providing accelerations in excess of 20 times the earth’s gravitational pull in normal operation and exceeding more than that in emergency shutdown situations, there is simply no room for error or accident. Admittedly, the thought of a free flying welding gun through the production area may be a bit dramatic, but there have been situations where certain safety precautions were not taken, either due to negligence or ignorance of the predetermined process. According to the United Auto Workers, the majority of accidents reported in the United States occur as a result of a worker found ‘inside the robot’s safeguarded or restricted space during its automatic operation.’ Few reports indicate machinery failure or malfunction. In part, this can be attributed to the safety measures inherent within the robot, its tooling and its environment. Opportunities to help ensure process safety at the employment of tool exchange systems are possible if the following key process factors are understood and implemented. Work Cell Zones The first line of defense in preventing accidental tool drops is to create a safe zone within the robot programming to ensure that the tool will only uncouple in areas that are predetermined as ‘safe’ whereby no harm will come to operators or equipment if a tool
is dropped. This work cell zone, defined in the robot controller, prohibits a tool from uncoupling if the robot is not within the programmed zone area. Coupling & Uncoupling Coupling and uncoupling represents the greatest opportunity to prevent unnecessary harm. Efforts can be made within the robot’s environment, as well as within the tool exchange system itself to ensure safety. Specific coupling and uncoupling considerations include:
This system does not transmit pneumatic pressure to the uncoupling valve until the robot has correctly set the tool into the final release position. While this is actually a feasible solution, practice has shown that the operator can, and sometimes will, override the switch manually to uncouple the tool. This situation, which occurs most often during line set up, debug and tool maintenance, is an unsafe practice. It is also important to note that a comparable electrical solution is equally suitable to prevent nonprogrammed release of tools.
• Sensors & Pneumatic Interlocks In addition to work cell zones, • Set Up & Programming sensors and pneumatic interlocks According to the US Department should also be integrated into the of Labor’s Occupational Safety and tool exchange system. While it is Health Administration (OSHA), not required to use both, it is good most problems do not occur during practice. Use of a sensor as part of normal operating conditions, the uncouple circuit must be made but rather during programming, to actuate, so even if the sensor is programme touch-up or refinement, unplugged, the tool changer will maintenance, repair, testing, set never uncouple. up or adjustment.

issues & insights
It is also important that the valve is commanded to be in the coupled state before applying pressure. Failure to do so can result in an accidental tool drop. Another factor to consider when using a tool exchange system, regardless of the type of latching mechanism, is to always incorporate the tool changer couple and uncouple sensors in the programming logic. By doing so, this will determine whether the latching mechanisms are engaged or disengaged from the tool. If this is not done, the latching mechanism may not fully disengage, which can cause the tool to be dragged out of the tool storage fixture and accidentally dropped. Control Of Actuation Valves Controlling the actuation valve to ensure proper coupling and uncoupling is another important safety measure to be taken into consideration. Control of the actuation valve can be accomplished through electrical interlock logic or pneumatic interlock logic.

Uncouple
• Pneumatic Safety Switch A pneumatic safety switch is an additional measure that can be employed. In this scenario, the pneumatic line to the uncoupled valve passes through a robot side mechanical valve that is only activated when the robot arm is in the designated end position at the tool station. Handling High Current When discussing the safety of tool exchange systems, another factor that must be taken into consideration is the voltage level of the current flowing through the system. In welding applications, there can be as many as several hundred amperes with voltages as high as 600 volts depending on the type of welding system utilised. If the tool changer is not adequately equipped to handle such current and degrades over time, a malfunction and subsequent tool failure may occur. Therefore, appropriate measures must be employed.

• Materials The materials used in the tool changer system must be durable enough to safely handle high current flow even under adverse conditions. Materials like FR4, a fiberglass epoxy laminate, provide a suitable dielectric constant to prevent leakage through the tool changer housing, eliminating such problems as sensor shortages, motors burning and even electrocution. In addition to durable materials, the insulation must also be able to withstand the welding current and prevent current transferring back from the welding gun.
High-KVA Touchsafe Contacts
When the tool changer is uncoupled the robot contacts must be ‘touch safe’
• Exposure Additionally, it is important that electrical operators on the floor are not exposed to hazards. In c o m p l i a n c e w i t h E u ro p e a n standards, when the tool changer is uncoupled the robot contacts must be ‘touch safe.’ This is especially important when changing from a welding gun to a gripper – highKVA to non-KVA. The robot side must be covered to shield the exposed high-KVA contacts. On occasion, in addition to the actual current carr ying contacts, so called ‘mass contacts’ are utilised that are capable of handling the total current capacity of all electrical contacts together. For example, with 3x200 amperes at 600 volts or respectively 120 KVA per contact, the mass contact must be able to handle a minimum capacity of 360 KVA. High Dynamic Robots As previously mentioned, newer robots that are designed to help reduce cycle time and generate greater productivity on the line have entered the market. Robots like the ABB IRB 6600, IRB 7600 and the Kuka KRC series can be characterised as ‘high dynamic,’ since they are capable of generating high dynamic forces, particularly at an emergency stop.

issues & insights
As a result, it is important that all tool exchange systems meet the stringent demands of these robots, both with direct mounting and more robust locking mechanisms. These high dynamic robots a re c a p a b l e o f g e n e r a t i n g moments and torques with tooling payloads in excess of half a tonne, with accelerations equaling as much as 20 times the earth’s gravity – especially at emergency stops where tooling payloads may easily reach or exceed 10.0 KNm at the base.
Heavy payload and high dynamicS
High dynamic robots are capable of generating moments and torques with tooling payloads in excess of half a tonne
Therefore, tool changing systems and locking mechanisms must be able to safely handle such load conditions and be able to provide more than the commonly projected 5 million change cycles without compromising accuracy or performance. • Deceleration/Emergency Stops The proper tool changer for these high dynamic robot models should be engineered for the ‘worst case’ robot capability and not the actual loads generated within a specific tool. According to ABB, in the extreme condition of full velocity, 24 industrial automation asia | June/July 2009
full reach, full payload and the worst case emergency stop, the IRB 6600 can generate a maximum of 10.0 KNm and the IRB 7600 can generate 14.0 KNm at the tool mounting surface. Similarly, the Kuka KRC series is capable of generating 9 to 1 6 G ’s a t e m e rg e n c y s t o p depending on the specific model at the tool mounting surface. These forces must be well below a tool changer’s failure point, providing inherent strength greater than the moments or torques generated by the robot even under the most adverse conditions. In an effort to reduce weight, older tool changers have traditionally been designed to mount to the robot via aluminum adapter plates, typically with six M8 or M10 screws. These mounting methods, which can not withstand the forces generated by newer robots, can become a dangerous failure point. Any tool changer that uses an aluminum adapter plate mounting between the robot flange and the tool changer may not provide the full moment and torque transfer given by the manufacturer’s robot mounting pattern. The same holds true for the replicate robot mounting pattern on the tool side of the robot. Such applications constitute unsafe practice and may present significant liability issues. One possible solution to this problem is to replace the aluminum adapter plate with steel. However, the additional weight and increased inertia on the robot or tool mounting screws reduces the available payload capacity for that robot. It is an essential safety requirement that the tooling equipment be capable of withstanding the maximum
forces that can be generated by the specific robot rather than just absorbing initial tooling concepts. This will protect the line builder and end-user through the life of the line from inadvertent overloads caused by process changes or tooling modifications, especially with new lines, which generally see more changes of this type. It is also important to note that all of these considerations not only apply to just the tool changer, but also to the tooling that is mounted to the tool changer. Safety The Priority P e rc e p t i o n s re g a rd i n g t h e utilisation of tool changer systems on robots have shifted from not only providing the utmost flexibility on the line, but also providing additional value by increasing throughput on lines that do or do not currently employ tool change systems. While it is clear that technological innovations within tool changers have brought greater efficiency and flexibility to automation, it does not imply that the basic safety issues can be ignored. To safeguard the protection of operators working on the line and the production output o f t h e l i n e i t s e l f re q u i re s redundancy – a series of safety measures with inherent checks and balances built into the tool change system.

One Small S te p For Automation Stepping motor control has evolved into developments of drivers with builtin controllers and supporting network compatibility. By Charles Lim C S, customer support centre manager, Oriental Motor n the automation field of today, there are several types of electric motors or actuators used in systems, which can be classified as those that need high positioning accuracy that would normally employ stepping motors or servomotor drives, and those that do not. Indeed, the factory automation of the future demands more complex systems, and also provides greater reliability and flexibility in control. Technological innovations have to create products that are to be more user-friendly, as well as to meet industrial standards and demands of the future. Conventional Stepping Motor Control Stepping motor systems have proved themselves to
be reliable in delivering the correct output for high accuracy positioning requirements, with minimum hassle and adjustments required. Figure 1 shows the typical open-loop control system configuration that comprises of a Host Controller (normally, a PLC is used), a controller, a stepping motor driver and motor unit. The controller (also known as a pulse generator) shown in the illustration will be programmed using a PC, where the position data for distance, speed and direction would be stored in individual programmes. When the host controller selects the required programme and executes it, the controller will send the information through pulses (Figure 2) for the desired motor operation.

Figure 2: Example of pulse waveforms from a controller
For example, if a stepping motor has a step angle of 0.72°/step, and it is required to turn 360° (1 revolution), the controller would need to set 360° / 0.72° = 500 pulses. If it is supposed to rotate that revolution within 1 second, the frequency set would be 500 pulses per second (pps), or also known as 500Hz. This open-loop control method does not need the use of feedback systems to determine its position, making setup easy and fast.
able to scan to the desired position manually and enter it as a desired position instead of determining it by calculating the number of pulses, making position setting more precise and easy.
Simplifying Control Using pulse lines for stepping motor control has proven to be a very reliable system for decades; however there are the occasional issues of noise interference from other peripheral devices, such as contact relays or power supply cables, which may affect the pulses sent to the driver. In some cases, a lower maximum frequency of transmission may result due to stray capacitance in long pulse line between the controller to the driver. An ideal situation would be for the controller and driver to combine together as one, which will help in reducing wiring, space and eliminating the issues related to the reliability of pulse control. Oriental Motor’s latest 5 phase stepping motor and driver package CRK Series offers a stored data type driver that allows the programming of the distance, speed and direction into 63 different programmes in the driver. Control would be easier where the higher controller would need to do is to select the correct programme and provide the start signal to execute the movements. Shown in the system configuration (Figure 3), setup is much more convenient without the need of 2 separate units, where all programmes are set using a data setter OPX-2A. It also provides better flexibility, such as the teaching feature (illustrated in Figure 4): the user is
Reducing Wiring Issues In industrial machines, the demand of positioning motors is normally more than just one axis. For control of multi-axes in a system, the host controller would need to provide sufficient input/output signal ports for all of the axes, and there may be several cables of various lengths connected to it. Wiring from every driver to the host controller is a hassle and in some cases, it may build up bulks of wires stretching throughout the machine, taking up space, weight and possible problems associated to misconnections or incorrect configurations, resulting in man-hours cost wasted on troubleshooting. It would be easier to manage and setup if the drivers were able to link up to each other; one way of reducing such wiring is to establish a network communication for all the axes, such as adopting a RS-485 communication network which is gaining popularity in a wide range of computer and automation systems. The CRK Series driver suppor ts RS-485 communication, with the ability to use a daisy-chain connection by linking from the drivers to each other using dedicated network cables as shown in Figure 5. Up to 31 drivers can be linked up, with each of them having a different identity by issuing a unique address individually (illustrated in Figure 6), and the last driver to have the terminal resistor switched on to prevent reflections of the bus commands. The master device is programmed to send out commands through the network bus line to select the correct driver by calling the address number, and execute the positioning operation accordingly without any lag time between each axis (hence able

to achieve synchronous stepping motor operations for multiple axes). Using RS-485 communication allows greater flexibility in determining the master device for control, such as using a Personal Computer (PC) with a RS-485 output. The significant advantage that can be achieved using network systems would be the much neater and easier wiring from multiple drivers to the host controller with less labour work required, reducing
the setup costs to a fraction of what is required for conventional methods. Detecting Missteps In factory automation machines where each axis is to perform specified processes and to co-ordinate with each other timely, a stopping position error (misstep) for a stepping motor may cause a serious problem to the entire system process if it remains undetected and not corrected. Misstep occurs when the motor operation fails to synchronise its movements with the input pulses due to possible overloading or when speed changes rapidly. For stepping motors with a 50 teeth rotor, misstep occurs when the position of the rotor displaces the stator teeth more than ±1.8° from its stable position, thereby snapping to the next stable position at 7.2° away. To detect any misstep occurrence and verifying if the correct position is met, the conventional way is to add an encoder to the shaft of a double-shaft stepping motor (or if possible, the application itself) to monitor the positioning real-time as a feedback. The CRK Series driver offers external encoder inputs to its driver, and is able to detect this occurrence as shown in the block diagram (Figure 7). When the stored programmes in the driver are executed, it would feed information of the correct pulse number to the motor drive circuit in order to rotate the stepping motor towards the correct distance, speed and direction. The movements of the stepping motors are captured by the external encoder to read the position by receiving the A and B phases to the Encoder Feedback Counter, and compared against the actual number of pulses that has the motor is commanded to move. If the difference between the command and feedback pulses exceeds the step out detection band of 7.2°, a Step Out signal will output to the higher controller to notify this. It is then up to the higher

controller to take the necessary action, such as programmed to produce an alarm output and halting the other axes processes so that the error could be corrected before production resumes again. Eliminating Missteps An easier solution to prevent and eliminate a misstep is to use a closed-loop stepping motor system, such as offered from the AR Series. In Figure 8, it shows the construction of the AR Series stepping motor that has a built-in resolver to function as a feedback system. The output signals of the resolver is shown in Figure 9, where it outputs two sine wave signals having a 90º difference (electrical angle) by utilising the change in inductance according to the position relationship of the rotor and stator. By going through a high resolution analogue-todigital converter, the driver would be able to read and monitor the position of the motor effectively. Compared to conventional encoders, a resolver system is simple and sturdy, without electronic components thus making it resistant to heat, and also enabling the motor to be more compact and thin. The control diagram shown in Figure 10 would be illustrating the closed loop system employed in the driver, where the rotor position counter and deviation counter would be reading the position data from the resolver as it rotates. The deviation counter would serve an important role by comparing the resolver readings against the pulses that has been sent in, and would activate closed loop control whenever a possible misstep is detected. Normally if the positioning deviation is less than ±1.8°, the motor is not considered to have any misstep, and thus be operating like a conventional stepping motor. However, if the deviation is more than ±1.8°, the control system would immediately switch to closed loop mode to prevent the loss of synchronism, and corrects the rotor position automatically to its designated position.
Stepping Into The Future As shown, the conventional stepping motor control has evolved into developments of drivers with builtin controllers and supporting network compatibility, with closed loop features to meet the demand of zero positioning errors. This will translate into savings and higher profits where with a more reliable and simple system, less downtime and man-hours are required to rectify possible machine problems, by which the machine could produce more consistent products with less defects within an operation day. Improved and easy to use features help the user to setup the equipment fast, which can reduce the stress involved in installation, and creates higher flexibility in positioning control for the future.

This ensures that the position to be achieved can be met with high reliability; in conditions (such as overloading) that prevents it from doing so, the current to the motor would cut off after a short interval, and the driver outputs an alarm signal to the host controller to notify this situation. Therefore, the use of closed loop stepping motor will prevent the possible problems associated with the errors in positioning effectively, bringing the reliability of an automated system to a higher level. There are other advantages can be achieved from closed loop stepping motors such as taking higher inertia loads more than conventional models, and able to achieve shorter positioning time with less acceleration / deceleration time needed, since it is able to prevent missteps in such conditions.

mall, fast and cheap PLC-solutions usually offer few engineering options and often do not provide convenient visualisation. In contrast, distributed control systems integrate a host of components such as controls, engineering tools, HMIs (human machine interfaces) and numerous peripheral devices and tools. The segment between PLCs and the world of control systems – the hybrid market – is currently being targeted by both sides. PLC components are becoming more powerful and they can therefore also process more complex tasks. ‘Lite’ control systems are being introduced and they are increasingly being installed in small to medium-sized applications with less complex automation tasks.
For small and less complex automation tasks with often only few signals standalone PLCs have been and are still used, because until now process control systems have been too expensive for these tasks. In the process industry many control tasks, eg compressors, centrifuges or steam generators, have been automated as PLC-based package units, leading to variety of different control systems and tools.

The advantages are obvious: efficient engineering, easy operating and maintaining as well as increased productivity due to intelligent diagnosis. It is now possible for smaller automation solutions, which to date have been dominated by PLCs, to benefit from the advantages of process control engineering, particularly in the process industry. There are opportunities for use in many industries, including chemicals, petrochemicals, oil and gas, metalworking, cement production, glass production, etc. ENQUIRY NO. 4302

Diminishing Returns The use of different PLCs brings serious disadvantages for the users: different tools increase the training budget and lead to more complexity, but without adding value. Particularly during maintenance, minor changes can cause considerable expenses, as cross-influences from different systems require manual adjusting. The differences in visualisation and operation as well as the individual alarm concepts used by the various manufacturers can, in extreme cases, even affect the availability and safety of the application and the total plant negatively. Additionally, the flexibility of the maintenance personnel is reduced because not all users can be familiar with all tools. Often older PLCs can only be maintained by a small number of specialists, many of whom are due to retire over the next few years. Procuring and storing spare parts for many different systems and products cause additional work and expenses. All these reasons result in higher costs for servicing and maintaining the plants. In contrast to PLCs, control systems are primarily based on analogue control loops with slow monitoring and control functions but less on fast positioning or switching operations. The process is operated and monitored in the control room. The systems and plants generally run continuously and often have very high demands when it comes to availability. Consequently, implementing changes must be possible in online project configuration. Additionally, repairing and changing of components while operating the plant is essential. Applications are often specifically configured for one project and the processes concerned and therefore require powerful and efficient engineering-tools with extensive integration possibilities.

The historian acquires and stores plant data, and integrates the real-time and historical plant data together into a common database. Shigang can then access all plant information, analyse, manage and report the data through different clients. As it is equipped with MS SQL Server2000, any application using SQL, ODBC or OLE DB can conveniently acquire data from it. Enabling The Connection T h e Wo n d e r w a re H i s t o r i a n enables the integration of almost all automation control systems that are installed in the plant. All these are entered into the realtime database system. In the company, there are d i f f e re n t s m a l l - s c a l e d a t a collection systems throughout the plant that were created using VB, VC, Forcecontrol and KingView etc. An OPC Server was developed to collect data from these different systems in the field into the historian. This helps to enable the real time data collection of discrete databases, and relationship databases such as MS SQL Server, Access etc.
Real-Time Information Nearly 90 percent of the data analyses in the real-time database are sent to the ERP and other applications. The system can not only provide traditional inquiry analysis functions like search by contract numbers, production order and furnace numbers but it also can search by specific keywords such as steel type, production date to better manage the manufacturing process.

Success For
hile macro consumer trends drive the need for more complex products, wider product ranges and increased ‘health and wellness’ benefits through food products, retail giants continue to exert considerable price pressure across the supply chain. At the same time, government agencies have much higher expectations of the food & beverage supplier and the ‘brand’ in terms corporate stewardship and transparency. 34 industrial automation asia | June/July 2009
And perhaps the biggest challenge of all is the sharp rise in input costs that is threatening the very viability of many food & beverage businesses, both large and small. Removing The Fats Soaring input costs combined with weakened output prices and demand have put food & beverage processing firms under considerable pressure. With dramatically changed conditions in the midst of the global financial
crisis, businesses are reviewing all input costs to identify and optimise in such a manner that profitability is protected for the short-term even as operations are refashioned to become ‘recessionproof’ for the long term. Raw Material & Labour Costs Some raw materials for food processing are currently priced at up to 50 percent above historical levels. Labour costs have also seen significant rises. To contend with these rising raw material and labour costs, the food & beverage industry has adopted several strategies. These include: • Search for more affordable ingredient alternatives or substitutes
• R e f o r m u l a t i o n o r n e w processing approaches to reduce production cost • Increased period of coverage on raw material contracts (to insulate from price volatility) • Price increases for endproducts; to help retain margins • Rationalisation / restructuring of operations across geographies • I m p r o v i n g o p e r a t o r productivity • Improving labour productivity through providing operations personnel real-time intelligence and visibility over all operational aspects of the plant Energy Costs Energy costs as a percentage of sales at large food & beverage companies are typically in the region of 10 to 15 percent, and rising. That is why it makes good business sense to take a closer look at these costs and explore avenues to minimise them. Electricity remains the largest energy cost for typical food & beverage plants. However, it is also the one area where significant savings can be achieved in the shortest possible time, if integrated energy management systems are used. Table 1 shows the main enduses and their typical proportion of total electrical energy consumed in a food processing plant:
To minimise energy costs, food companies are looking to: • Implement process improvements that save energy (such as optimising heat recovery through processes) • Revisit process parameters such as temperature, pressure and time to identify opportunities for fine-tuning those parameters such that process requirements are met, but energy savings are achieved where possible • Leverage process control tools more effectively to realise energy efficiencies Packaging & Transportation Costs Given the fact that food & beverage is essentially a mass market with a large number of products manufactured, stocked, distributed and sold, the potential for savings from seemingly small changes to packaging can shave off millions of dollars in overall packaging, transportation and disposal costs to companies. To manage rising packaging and transportation costs, food companies are focusing on: • Lighter-weight packaging or shrunk packaging to reduce packaging, transportation and disposal costs (For example, in 2007–08, Coca-Cola eliminated 40 million pounds of plastic annually in the US

Compliance Costs As accountability becomes a key performance indicator for food businesses, compliance requirements have increased. Some of these include: • The 21CFR part11 regulation, stipulated by the food and drug administration (FDA) of the United States • The EU's 178/2002 EC regulation establishing the European food safety authority and requiring food manufacturers to be able to track and trace the products they manufacture. • T h e U S B i o Te r r o r i s m Act, which requires that manufacturers should be able to provide tracking and tracing information about a product within four hours • Other requirements including compliance with current good manufacturing practices (cGMP) and the Sarbanes Oxley Act Beyond standard compliance and traceability obligations, companies see the need for builtin quality and safety assurance systems since a product recall (on account of a health risk) could jeopardise the very viability of the brand or supplier.

This is because the damage done is not merely the substantial financial write-offs (sales loss, disposal cost, replenishment cost, legal and investigative costs) but also the sometimes irreparable damage to credibility and brand equity. To help meet their compliance obligations effectively, companies are looking to: • Improved quality control and safety systems; especially for Hazard Analysis Critical Control Points (HACCP), clean-in-place (CIP) etc • Greater visibility across the whole supply chain; to guarantee traceability The Right Ingredients To contend with the many rising costs, plant managers and operators at food & beverage facilities need to focus on three steps that can take them towards optimised operations. 1. Measure There can be no effective monitoring or managing of production efficiency if production variables are not measured in the first place.
Food and beverage companies are implementing sophisticated SCADA/HMI systems because of the huge number of ingredients and processes, product formats and packaging, which are involved in the production process and the consequent difficulty in tracking such a wide variety of process variables in real-time. Measures that most processors consider critical to optimisation include overall equipment effectiveness (OEE) and key performance indicators. While not a new approach, OEE is only now being recognised as a key measurement of efficiency in manufacturing processes (at machine, manufacturing cell or assembly line levels). OEE is a factor of three variables – availability, performance and quality. Of course, with the food & beverage sector there are certain peculiarities that may not apply to other conventional processing facilities. For example, seasonality of some ingredients or raw materials could mean that certain processes or equipment are run only for certain periods in the year. This means that conventional
Potential for savings from seemingly small changes to packaging can shave off millions of dollars in costs 36 industrial automation asia | June/July 2009
ROI calculations cannot be applied in some cases; and that demands a plant-wide monitoring solution that can be both flexible and easily customisable. Certainly, one of the critical success factors in any measurement effort is the completeness of information gathered. This can be challenging when the food & beverage plant has different proprietary control systems in use. 2. Monitor Leveraging SCADA systems to collect a wide variety of process data, plant managers and operators can then monitor their processes with the goal of optimisation. Opportunities to look for could be: • Identifying potential equipment failure/deterioration to avoid large upfront costs for equipment replacement as well as lower productivity, when timely repair will do • Identifying variability in processes that result in wastage of raw material, delays, excessive equipment wear or surges in energy demand • Reviewing energy consumption trends over time • Linking energy peaks and troughs with specific product types, processes or times of operation • Monitoring production line changeover times to seek possible reductions in duration • A s s e s s i n g q u a l i t y - c h e c k success rates • Identifying potential installation of variable speed drives (instead of direct on line motors) • Identifying potential for power factor correction In the effort to structure p ro c e s s e s a n d a p p ro p r i a t e control solutions to monitor those processes, some of the emerging
Macro consumer trends are driving the need for more complex products, wider product ranges and increased ‘health and wellness’ benefits through food products
standards of relevance are: • ISA-88, the international standard for flexibility in production, which provides models and terminology for structuring the production process and for developing the control of equipment • ISA-95, the international standard for the integration of enterprise and control systems, which provides models, which are the basis for the development of standard interfaces between ERP and MES systems food & beverage companies supporting such standards include Nestle, Mars, Arla Foods, Kraft Foods, etc 3. Manage Measuring and monitoring do not in themselves translate into positive outcomes unless food companies proactively manage the data and insight derived from those processes. It is here that the robustness of the SCADA solution and reporting solutions comes into play. For example, systems that facilitate almost immediate batch identification in a ‘compromised’ batch of products (that are out of specification or beyond permissible health/safety thresholds) can help save the company considerable time, effor t and monies by ensuring that the batch concerned is isolated anywhere along the supply chain and diverted from consumption, the process itself is audited and re-calibrated for a return to desired results. Or systems that can help managers and operators spot a
production process drifting out of nameplate specifications can help save the company significant amounts in raw material that could have been wasted or equipment that could have suffered undue wear. To help deliver such benefits, SCADA systems and reporting tools need to be: • Reliable/available • Flexible/customisable • Open and scalable/modular • User friendly (with the look and feel that is readily understood and usable by operators and engineers) • Robust and feature-rich in terms of clustering options, alarm management options and analysis tools • Well integrated with business systems through powerful reporting tools that provide internal stakeholders (such as senior management, finance or quality control departments) and external stakeholders (such as regulatory bodies) accessible and actionable insight from the plant-floor • Well supported (by vendors and system integrators who understand the unique needs and priorities of the food & beverage sector and are effective in rapid problemsolving) The Winning Recipe I n m a n y c a s e s , u n re l i a b l e and inconsistent manual datagathering and documentation is still undertaken and small-sized food & beverage facilities might only have pockets of automation and control, if at all.
Not surprising, given the fact that the large multinational food & beverage companies with a global presence still account for only a small fraction of the total food & beverage market (which, on the whole, is extremely fragmented and cluttered with small to medium-sized suppliers). However, in many cases, even those plants equipped with modern SCADA systems and sophisticated reporting tools fail to achieve optimisation goals not because of the inadequacies in those tools. Rather, it is a combination of several factors including: • Lack of specific and shared goal-setting for optimisation efforts • Lack of clarity in terms of data/ insight needs and priorities • Lack of a holistic / integrated optimisation plan • Underutilisation of the data, t re n d i n g a n d o v e r l a y i n g possibilities in tools such as SCADA • Inadequate vendor / system integrator support in customising solutions for specific requirements • Lack of open solutions and inability to connect with proprietary legacy systems • Inadequate leverage or absence of manufacturing execution systems (MES) and benchmarking tools Companies that are aware of these pitfalls and seek to overcome them with the assistance of reliable SCADA solutions and secure reporting tools, backed up by appropriate vendor and system-integrator support, can turn the current challenges into opportunities and build into their operations the recipe for success even in the most difficult of times.

A condition-based maintenance programme eliminates downtime on an oil platform. By Ben Dong, ICM product manager, Rockwell Automation China
42 industrial automation asia | June/July 2009
The Challenge Efficient, non-stop operation of pipeline pumps is key to costeffective oil production. Initially, preventive maintenance was C A C T ’s s t a n d a rd a p p ro a c h to keeping the pumps online. However, the effectiveness of their maintenance system was limited. They were forced to react to equipment problems that went undetected during routine inspections. To improve their system, the group began to use Rockwell Automation products to monitor the pumps on three of its offshore platforms in the mid-1990s. Initially, CACT based their system on portable equipment – Entek Datapac and the Allen-Bradley VISTeC. The DataPac is a portable instrument that collects field data, including process variables and vibration information. The VISTeC vibration meter measures vibration in units of velocity and acceleration and can also take spike energy measurements, which can be used for early detection of surface flaws in rollingelement bearings. Temperature and running speed measurements can be acquired as well.
The Solutions Rockwell Automation worked with CACT to develop a solution that would meet the oil producer’s needs and preserve their initial investment, proposing a remotely accessible, condition monitoring solution that would incorporate the existing portable equipment with an Enwatch system and XM modules. Emonitor software gives them the ability to store the data from the XM modules and Enwatch system and compare it against the
data that they originally received from their portable collectors. Via an onboard Ethernet network, the Enwatch system provides scheduled monitoring of all the pumps on the platform. Measurement parameters include vibration and process variables. On the same network, XM intelligent modules process critical parameters used to assess the current health – and predict the future health – of the pumps in real-time. The XM Series is comprised of DIN rail mounted measurement, relays and process modules. Ideal for critical machiner y, the system includes protection capabilities, which can be used to safely shutdown a machine before significant damage occurs. For example, if the system detects vibration outside of set parameters, it will send a signal to the motor control centre (MCC) to turn off the relevant motors and protect the pump. Appropriately configured, the system meets API 670 standard. CACT operators onshore can remotely configure the XM modules via a DeviceNet network and view the equipment status through PlantLink, an interface that provides a graphical representation of the health of all the machinery being monitored online. Information from the condition monitoring system is also integrated with Rockwell Software Maintenance Automation Control Center (RSMACC), where appropriate maintenance is scheduled in accordance with equipment requirements. The Results With the condition monitoring system in place, CACT has eliminated the need for manual data acquisition – and the associated costs. Onshore operators 200 km from the platform collect, configure and analyse data just as

Emonitor software was used to store the data from the DataPac por table data collector. To implement any needed repairs, CACT contracted for maintenance through a third party at a charge of US$100,000 per year. CACT was pleased with the performance of their offline, portable system. At the same time, there were limitations. For example, the Datapac portable could detect vibration changes, but as a portable unit, it could not track and analyse the pump’s condition in real-time. Also, the data acquisition process itself was very costly. To obtain the readings, CACT periodically sent maintenance personnel by helicopter to the platforms at a cost of US$2,000 per visit. In fact, the yearly transportation expense exceeded the installation cost of the online system. Finally, the current offline system could not provide the realtime pump protection outlined by the American Petroleum Institute (API) Standard 670. The API 670 is the most widely adopted standard for machinery protection in the world. CACT required a system that would provide real-time equipment monitoring and API 670 compliance – and help contain their maintenance costs.
Maintaining equipment typically located hundreds of kilometres from shore can be a costly and time consuming proposition
they would on a local server. Since applying the Enwatch and XM systems, CACT has reduced their unscheduled downtime from 2.43 percent to 0.67 percent – a 72 percent decrease. In fact, during a five-year period, the system has prevented machines from catastrophic failures more than 20 times. Thanks to a condition-based maintenance strategy, annual maintenance expenses have also decreased significantly. In fact, the drop-off in service time was so dramatic that CACT saves US$100,000 in third party annual maintenance costs annually. ENQUIRY NO. 4503 June/July 2009 | industrial automation asia 43

tatutory product labeling requirements for sterile medical supplies and drug products present a particular challenge on the packaging line. However, late stage customisation means that faster machine run times can be achieved even with falling batch sizes, although a flexible packaging line configuration is essential. Packaging solutions have become a kind of second skin for many products. As well as having to preserve the function of the products during transportation and storage, they also fulfill a presentation, labeling, information and documentation role. This is particularly true in the case of sterile medical supplies, where the safety aspect is an absolute priority. Any shortcoming could place people’s lives at risk.
Packaging:

Efficiency
Quality & Productivity The wide variety of packaging types and the requirement for extremely high output rates in some cases, along with strict laws on consistent product quality, mean that fully automated packaging lines are essential. While the huge range of packaging types can only be handled with flexible packaging machines on which format dies can be changed almost at the touch of 44 industrial automation asia | June/July 2009
a button, the high speeds required can only be achieved with the aid of automatic multi-axis robots which can be integrated as seamlessly as possible into the line. The requirement for consistent product quality, which has to be reproducible – regardless of human intervention – and objectively verifiable, can only be met with sophisticated checkweighers and various types of inspection devices (seal testers, X-ray inspection

devices, vision systems, etc). The continuous tracking and traceability of batches and the documentation of these processes calls in turn for advanced identification, labeling and direct printing systems. A Single Source All of these functions should be linked into a complete packaging line as standalone modules. They can then be networked and controlled by means of an industrial computer (line of control). This control unit can be used for the coordination of functional elements, product tracing, product conversion, and connection to ERP systems for order management as well as to systems for the recording of machine and operating data. Given the complexity of this ‘automation network’, it stands to reason that the more components are sourced from a single supplier, the easier it is to integrate the individual modules. Naturally this is only feasible if the supplier can offer a broad enough product range. In such a case the supplier will also be willing to help configure the packaging line or even take over control of the project entirely, thus guaranteeing delivery of a
fully integrated system. The advantage for the line operator is that he or she can deal with just a single contact, who is responsible for the project and its successful implementation and who has a detailed understanding of the individual system components. The uniform line control system mentioned earlier means that there are fewer interfaces to control. This simplifies the running of the line and reduces training and operating costs. What’s more, the supplier of the integrated packaging line can create a standard validation document, minimising paperwork for the line operator. Batch Sizes & Line Efficiency Medical supplies and pharmaceuticals are subject to stringent legal requirements with regard to exact labeling. These requirements relate to seamless product tracking and batch traceability as well as to the obligation for products to be labeled in the local language and the need for the type of labeling to comply with national laws. Compliance with these requirements is leading to a steady reduction in batch sizes, especially when manufacturers
are supplying to smaller markets too. At the same time customers expect shorter delivery times to enable them to minimise their inventory levels. Diminishing batch sizes arising from country-specific and customer-specific (labeling) requirements lead to an increased demand for flexible delivery and labeling systems in order for the extensive packaging lines used for medical supplies to be operated with optimal processing and cost efficiency. Size Matters For instance, small batch sizes soon lead to inefficient process results if all the components of a packaging line are connected in series in the conventional manner. The ratio of setup time to run time becomes disproportionate in such cases. If the same range of medical products has to be packed in blister packs for 20 or 30 European countries on a single packaging line, for example, but the packs have to be labeled differently for each country, then even without making an exact calculation it is obvious that with a conventional line configuration the changeover times will far exceed the run times.

Line efficiency can fall below 30 percent in some cases, since the changeover process is not simply a matter of flicking a switch. It involves a whole series of activities: cleaning and inspection of the line for residues, installation of the new (print) module, and not forgetting documentation of all these activities. Late Stage Customisation By separating out some of the process elements, especially in the labeling area, sub-processes for different batches can be bundled together, reducing setup times. To give a specific example, the blister packing, cartoning and printing processes can all be carried out quite separately. Bundling batches for different countries and then separating them again afterwards introduces the possibility of late stage 46 industrial automation asia | June/July 2009
of course, but this type of configuration change is far quicker and more cost-effective than continually resetting the entire packaging line. Once again this highlights the flexibility of the packaging process. Late stage customisation not only brings about a clear improvement in cost structures for the packaging of medical supplies by increasing machine run times but it is also a flexible just-in-time component within the packaging process as a whole. The ‘identification’ sub-process can be further optimised by using a direct printing system. This avoids the need to stock preprinted labeling materials. The print quality of direct printing systems is getting closer all the time to that of preprinted materials. Possible print formats include barcodes and graphics.
Late stage customisation is only really viable if the automation chain has an open architecture into which all modules can easily be integrated customisation, where packaging is customised at the last possible moment. A handling module is needed for this solution to store the bundled blister packs containing the various countr y-specific batches – which are identified by machine-readable country codes – on a temporary basis and then transfer them to the identification unit when required. This always has to have the correct country-specific settings,
Late stage customisation is only really viable if the automation chain has an open architecture into which all modules can easily be integrated. This applies in particular to the modules which have been taken out of the main packaging line to run in parallel, for example t h e d e l i v e r y, i n t e r m e d i a t e storage, printing and packaging modules.

An examination of the benefits of a single control platform in packaging machinery. By Pete Lawton, electrical engineering manager, Pearson Packaging Systems
Standardise!
hen machinery is sourced f ro m v a r i o u s o r i g i n a l equipment manufacturers (OEMs), ensuring cohesive communication from machine to machine can be challenging. One approach to simplify that communication is through the use of standardised Packaging Machine Language (PackML). PackML started out as an initiative by the Open Modular Architecture Controls User Group (OMAC) and has since evolved into a fully functioning, standardised machine language. The Benefits Aside from the uniform ‘look and feel’ that it provides amongst machines across the plant floor, some of its other benefits include lowering engineering costs for both OEMs and end-users, increasing reliability and Overall Equipment Effectiveness (OEE) and reducing total cost of ownership (TCO) through easier integration, faster startups, and easier ongoing maintenance. 48 industrial automation asia | June/July 2009
PackML provides the ability for end-users to communicate to packaging machiner y and packaging machines to talk with one another. The end-user can easily programme supervisory systems to look in the same place in every machine on the packaging line and gather the same data by formatting how the data is captured and stored in the controller’s memory. This data can be faults, production information, downtime information, and other key details for maintaining uptime. All of this has been defined down to the tag in the database. This eliminates the need for end-users to write custom interfaces to each piece of machinery on the packaging line; end-users can now create one interface and use it multiple times. Boon For OEMs For the OEM, the implementation of PackML helps in several ways, including eliminating the time and
expense of going through extensive programming specifications, eliminating the need for engineering to spend large amounts of time rewriting code that is already proven, eliminating the schedule delays which come with writing and testing custom programming and providing the customer with a pre-formatted, standard interface that is both, cost effective and reliable without compromising the machine’s OEE. By using PackML, OEMs may significantly reduce and even eliminate large up-charges to endusers, allowing them to compete better in the marketplace. Additionally, the OEM service department always knows what they will see in the field regarding the programming of the machine. This eliminates the need for an engineer to be on-site during start-up and/or special training regarding the custom programming for a field service technician. ENQUIRY NO. 4602

Market Report
US Demand For Green Packaging To Approach US$44 Billion In 2013 US demand for green packaging is projected to increase 3.4 percent annually. By The Freedonia Group
US demand for green packaging – comprised of recycled content, biodegradable and reusable packaging – is projected to increase 3.4 percent annually to US$43.9 billion in 2013, using 59 billion pounds of material. Growth will outpace overall packaging but will remain modest due to the maturity of many products and the fact that recycled content packaging has a large existing presence in paperboard and metal packaging. Drivers Of Growth The fastest gains are anticipated for biodegradable plastic packaging and plastic recycled content packaging. Biodegradable plastic packaging is forecast to climb nearly 13 percent per year through 2013, driven by increased price competitiveness with conventional resins, rapidly expanding capacity and lower pricing volatility than petroleum-based plastic packaging materials. Additional stimulants include enhanced performance properties brought about by more sophisticated polymerisaton and blending techniques; efforts by brand owners to improve the environmental footprint of their packaging; and legislative bans on polystyrene foam foodservice disposables in some parts of the country.

W h i l e re c y c l e d c o n t e n t packaging demand is expected to increase in line with the overall green packaging average, ro b u s t g ro w t h f o r p l a s t i c recycled content packaging will be aided by more concerted ef for ts to boost collection volume, an increased focus on the development of food-contact approved resin grades, and further sustainability initiatives by plastic processors and brand owners. Gains will be moderated by slow growth for paper recycled content packaging, which is dominated by the large but mature corrugated and paperboard box segment.
Reusable Packaging Reusable packaging is forecast to expand more slowly, held back by marginal growth for drums, which face competition from larger formats such as intermediate bulk containers (IBCs). More favourable prospects are anticipated for reusable plastic containers, IBCs and other reusable packaging types. In general, value gains will decelerate sharply from the 20032008 pace due to an expected moderation in raw material prices, especially for plastic and steel. The relatively long service life of most reusable packaging also limits the need for replacements, a factor that restricts growth in demand for new units. ENQUIRY NO. 4603

The focus has shifted to using non-food plants, or energy crops to produce biofuels. By Augustine Quek
that has been dead for millions of years. For most of human history, the biofuel used is wood. Biofuels are considered carbon neutral because the plants used to produce biofuels absorb CO2 from the atmosphere. This offsets emissions during fuel consumption (Figure 1). Biofuels are also renewable and thus considered sustainable. Increasing Interest These factors, together with near record oil prices, have sparked keen interest in biofuels worldwide. According to IEA, global biofuel production has tripled from 4.8 billion gallons in 2000 to about 16.0 billion in 2007, but still accounts for less than 3 percent of the global transportation fuel supply. About 90 percent of production is concentrated in the United States, Brazil, and the European Union (EU). However, this could change if development programmes in other countries, such as Malaysia and China, are successful. Currently, two biofuels can now be produced in large enough quantities to have an impact on the energy market: ethanol and biodiesel. Bioethanol is an alcohol commonly produced through sugar fermentation. Ethanol can be blended with gasoline in a

mixture (up to 15 percent ethanol by volume) without requiring any modifications to most existing car and truck engines. However, ethanol has only about 60 percent the energy content of gasoline, and cannot be transported through the
existing pipeline infrastructure. Biodiesel is now produced from plant or animal fats. It can be blended in substantial amounts with traditional petroleumderived diesel or in some cases used directly as a transportation fuel. Biodiesel also has the added advantage of being cleaner-burning than diesel. However, the total quantity of plant oils that can be produced worldwide cannot cover a significant proportion of current diesel needs.
government put a moratorium on expanded use of corn for ethanol because of rising feed prices and is promoting other feedstocks that do not compete directly with food crops, such as cassava, sweet sorghum, and jatropha (an oilbearing plant originally from South America). Second Generation Biofuels Therefore, the focus has shifted to using non-food plants, or energy crops to produce biofuels. The

There is worldwide criticism on the use of food crops for biofuels
Another problem with current biofuels is that the leading raw materials, or feedstocks, for its production are corn, sugar, and vegetable oils. This has sparked worldwide criticism on the use of food crops for biofuels. According to the International Monetary Fund, world food prices rose 10 percent in 2006 because of increases in corn, wheat, and soybean prices, primarily from demand-side factors, including rising biofuel demand. The Chinese
goal is to switch from using edible feedstocks to cellulosic waste as the source of fermentable sugars for biofuel production. Energy crops are divided into two broad categories: grasses and trees. Grasses are suitable for producing biofuels because they are particularly efficient at photosynthesis and can grow fast. Similarly, fast-growing trees provide wood based material for biofuel production. These vascular plants
are composed of many large molecules, from which biofuels can be harvested. Besides cellulose, there are hemicellulose and lignin. Each is made of chains of smaller molecules, and all three are often bound together in a complex structure called lignocellulose. Although there are many ways these long-chain molecules might be turned into fuel, fermntation to ethanol is still the most common process, hence the term ‘cellulosic ethanol’. One company using grasses is Californian firm Ceres. The company is identifying desirable genes in fast growing grasses, specifically switchgrass, miscanthus, sugarcane and sorghum, and using a combination of traditional hybridisation and genetic engineering to increase their growth rate. The chosen grasses also thrive in a range of climates. Switchgrass and miscanthus are temperate. Sugarcane and sorghum are tropical. The company proposes to extend their ranges still further by creating strains that will tolerate heat or cold or drought or salt, allowing them to be grown on land that cannot be used for food crops. That will make them cheaper, as well as reducing the competition between foods and biofuels. Increasing the growth rate of trees are being the investigated by firms such as ArborGen, of Summerville, South Carolina. ArborGen is working on four species: eucalyptus, poplar, and the loblolly and radiata pines. It is applying similar techniques to those used by Ceres to speed up the growth of these trees and to increase their tolerance of cold. In addition to creating raw materials for biofuels, ArborGen also hopes to produce paper pulp, timber and other biomaterials. Creating Biofuels After harvesting, turning the June/July 2009 | industrial automation asia 53
energy
feedstock into biofuels is a tedious process. One promising process involves drying and then heating the cellulosic material to high temperatures, with little or no oxygen present. The long-chain structure breaks up in a mixture of smaller molecules, such as carbon monoxide and hydrogen, called syngas (short for synthesis gas). This process is called gasification. With suitable catalysts, syngas can be turned into fuel. One advantage of this process is that multiple types of feedstocks can be used. Many firms have used the gasification approach to produce feedstock syngas for biofuel production. Choren Industries in Freiburg, Germany, and Range Fuels in Treutlen County, Georgia, both use chippings and other forestry and timber-mills wastes. Choren is making hydrocarbon diesel while Range produces ethanol.
Bioethanol is commonly produced through sugar fermentation 54  industrial automation asia | June/July 2009
Another strategy, employed by Coskata, a firm based in Illinois, USA, is to use patented microorganisms and transformative bioreactor designs to produce ethanol from this syngas. An alternative to the syngas method is to break the cellulose and hemicellulose up using biological catalysts, or enzymes. Many firms have developed enzymes that break down biomass in this way. Iogen, of Ottawa, Canada, was one of the early pioneers in enzymatic cellulose depolymerisation. Its enzymes decompose cellulose and hemicellulose into sugar monomers. The lignin is burned to generate heat for the process. Abengoa, a Spanish firm that is also involved in solar energy, uses this approach as well. At least one firm, Mascoma, in Lebanon, New Hampshire, employs a single species of bug, Thermoanaerobacterium saccharolyticum, both to break down the biomass and to digest the resulting sugar. Mascoma will use both grass and wood as feedstocks to produce ethanol. Alternative Fuels Another important technological shift will be toward the production of other biofuels such as butanol and hydrocarbons and away from ethanol. Both butanol and hydrocarbons such as terpenes are much more gasoline-like, have higher energy content, and posses none of the drawbacks of ethanol as a transportation fuel. Recent heavy investments in research and development in this area by multinational corporations attest to its viability. Amyris Biotechnologies, based near San Francisco, uses a range of micro-organisms (bacteria, yeasts) to turn sugars into a group of compounds call terpenoids, mixture of alkanes and aromatics. Amyris claims it is at a cost competitive with diesel.
Another Californian company, LS9, is also using special microbes to produce alkanes for petrol and fatty acids for biodiesel, and other high-value chemicals. Synthetic Genomics has a similar approach, by designing, synthesising and assembling specifically engineered cells to produce biofuels. In each case, however, what is made is a chemical precisely tailored to its purpose, rather than the ad hoc mixture that comes out of a refinery. The rival companies thus argue that their products are actually better than oil-based ones. It is also possible to use purified enzymes to do the conversion from sugar to fuel, as well as from biomass to sugar, and at least two firms are working on applying them to the whole process. Codexis, based in Redwood City, California, has created a range of enzymes by a method akin to sexual reproduction and natural selection. Last year it signed a deal with Shell to use this technique to produce biofuels of various types. And a Danish firm, Danisco, has teamed up with DuPont to do the same thing with its own proprietary enzymes. Shell is also investing money in a project to turn sugar into hydrocarbons, this time by straight chemical processing. The technology involves a set of proprietary nonbiological catalysts provided by Virent Energy systems. Virent’s proprietry Bioforming process can convert a wide range of biomassderived feedstocks to fuels and chemicals, such from hydrogen to ketones. Oil and gas giant BP is backing one of the biggest academic projects intended to look into biofuels, the Energy Biosciences Institute (EBI), to the tune of US$500 million. The EBI is a partnership of the University of California, Berkeley, the Lawrence Berkeley
R Elam, US
converting it to fuels is now possible. Singapore scientists claimed to have accomplished this feat recently. According to the scientists at the state-backed Institute of Bioengineering and Nanotechnology, carbon dioxide can be turned into alcohols using a process that uses less energy than previous attempts. They used non-toxic organocatalysts to make ethanol, a biofuel that is also used as an industrial feedstock. The research team used N-heterocyclic carbenes (NHCs), an organocatalyst in the chemical reaction with carbon dioxide. Hydrosilane, a combination of silica and hydrogen, is added to the NHC-activated carbon dioxide, and the product of this reaction is transformed into methanol by adding water through hydrolysis. Hydrosilane provides hydrogen, which bonds with carbon dioxide in a reduction reaction. This carbon dioxide reduction is efficiently catalysed by NHCs even at room temperature. A 2005 joint study by America’s Depar tments of Energy and Agriculture revealed even with only small changes to existing practice, 1.3 billion tonnes of plant matter could be collected from American soil without affecting food production. The study also reported that 5 percent of electric utilities and 10 percent of transportation fuels in America will use biofuels by 2020. Biofuels will likely be part of a portfolio of solutions to high energy prices, including conservation, energy efficiency, and other alternative fuels. This increased reliance on plants would mean a better understanding, and relationship between humans and nature in the future.
Biodiesel has the added advantage of being cleaner-burning than diesel
National Laboratory and the University of Illinois. In addition to biofuels, the institute also researches the social, economic and environmental implications of using plants instead of oil for energy needs. One example would be glucose, the most common monomer sugar, would be turned into fuels and maybe even the bio-equivalents of petrochemicals—bioplastics, for example—in local factories and then shipped around the world. The institute predicts that would be a boon to tropical countries, where the rate of photosynthesis is the highest in the world. The third possibility is the use of algae as a source of oil for biodiesel p ro d u c t i o n . Te c h n o l o g i c a l improvements in the efficiency of growing algae and oil recovery are needed for algal biodiesel to be economic, but steady progress toward those goals is being made. One problem is harvesting the oil that is produced. Currently, methods for extracting algae
from the ponds, drying them and breaking the cells to obtain the oils are too expensive. This process is so tedious that some companies are considering the idea of burning the dried algae in power stations instead. One way is to modify the genetic makeup of algae. One firm that is doing that is Synthetic Genomics. To overcome the oil-collection problem, Synthetic Genomics’s algae have been genetically modified to create new secretion pathways through their outer membranes. This causes the algal cells to expel the oil almost as soon as they have manufactured it. It then floats to the surface of the pond, allowing it to be skimmed off and turned into biodiesel. The algae are also engineered to make more oil than their wild counterparts. Direct Synthesis Even plants and algae may soon be unnecessary in the production of biofuels.

Hoerbiger: Pressure Regulator Modules
Jumo: Electromechanical Thermostat
Pressure regulator modules from Hoerbiger convert electrical signals into efficient pneumatic operating power. The robust design enables on/off and proportional precision control. Through additional purely pneumatic power transmission, high actuating forces and torque are decoupled from the electric control power. As a result, the intrinsically safe control of the valve position is ensured across all performance classes of pneumatic actuators. The piezo technology provides access to the intrinsically safe automation of valves in a very wide range of temperatures. All fail-safe functions are possible as an integral part of the system, without additional valves.
The Jumo HeatTherm-DR DIN rail mounted electromechanical thermostat have ‘Push-In’ terminal technology; There’s no tool to connect the wire or the strand with the ferrule and the wiring is more reliable. The technology allows loads up to 16 A to be directly connected at 230 V AC. Maintenance costs are reduced, thanks to the small interval of <10 K from the point of shutting off the safety temperature limiter to turning it back on. The following are available: temperature controller (TR), operating temperature monitor (TW), safety temperature monitor (STW) and safety temperature limiter (STB).

the input of energy and raw materials. A further ‘hot topic’ was industrial IT and virtualisation. The spotlight was also on RFID and communication solutions based on GSM, UMTS, Bluetooth, ZigBee, WLAN und WirelessHART. The exhibitors were optimistic about the future. In many cases the lull in business provides companies with an opportunity to realise long-planned improvements. Said Dr Eberhard Veit, CEO of Festo: “Solutions are being developed for the time after the crisis. What we sow in 2009 we will harvest in 2010.” Angela Josephs, press spokeswoman of Phoenix Contact, drew a similar conclusion: “Despite the travel restrictions affecting our overseas visitors, we had a lot of high-level discussions and generated new contacts. The mood in the exhibition halls was very constructive and positive.” Motion, Drive & Automation The power transmission and fluid
The thirteen trade shows provided a comprehensive insight into state-of-the-art industrial technology. power industries made a strong showing at their flagship fair. The 1,234 exhibitors occupied seven exhibition halls. Energy efficiency was a recurrent theme in all sections of the show – as evidenced, for example, in the latest hydraulic components, electric transmission systems and warehousing systems. There is a pronounced trend towards condition monitoring and maintenance management systems. The continuous improvements in sensor technology have provided the basis for enhanced networking and the realisation of smart and adaptive process monitoring architectures.

Aerospace Supplier eXchange (ASX) 2009 The economic situation may not be all that rosy but as demonstrated by ASX 2009, it doesn’t mean it is time to head for the hills. By Joson Ng Welcoming over 2,600 visitors through its doors, the inaugural Aerospace Supplier eXchange (ASX) was held at the Singapore Expo from May 27 – 29, 2009 where exhibitors were mainly made up of tier three and four suppliers. “I think it is ver y hear t warming for us the organiser to see the number of exhibitors and international buyers we attracted. I thought that the turnout for the opening ceremony was fantastic,” says Gary Nutter second VP, A s s o c i a t i o n o f A e ro s p a c e Industries (Singapore). In line with the focus of ASX, the Global Asia Trade Exchange (GATE) 09 aerospace, a platform that enables the interaction between the suppliers and the buyers was held in conjunction with the main event. “It is about giving people the opportunity to meet and talk about what they can offer. The success of GATE depends on the forces of supply and demand. Hopefully some deals will come out of these meetings, maybe not today but somewhere down the road,” says Mr Nutter. Speed Dating Process GATE 09 Aerospace was coorganised by IE Singapore, an agency in-charge of the development of Singapore's external economic wing. The GATE concept was implemented for the first time in 2004 and made its aerospace debut in ASX.
“Though a first for an aerospace event, but this is not the first time we are organising GATE. In the past, we have organised these events catering to other industries,” says Thian Tai Chew, director, technology business division, IE Singapore. The concept of GATE involves inviting buyers from all over the world to speak to local enterprises in order to explore the possibility of building a long lasting business relationship. “By inviting buyers to come down rather than sending our companies overseas enables the potential buyers to meet a lot more suppliers. They can also see for themselves the manufacturing scene in Singapore. We feel this is a successful programme so we will continue to take this approach,” Mr Thian says.
Singapore and A*Star to address the issues. The aerospace sector may be shrouded with uncertainties at the moment but Mr Thian has no doubts about the industry. He concludes:” One thing is for sure, this group of suppliers have the potential to grow.” From the organiser point of view, Mr Nutter feels that it is important to get the right exhibitors and buyers. Organising the event around conferences is also part of the plan to help attract a wider group of audience. Lastly, he hopes to see improving economic situation by the back end of this year or early next year. As such, he hopes that the next ASX will be bigger to showcase more companies.

Flying Without Wings
High-speed trains are gaining popularity throughout Asia, putting the metalworking industry in high gear. By Joson Ng
anâ&#x20AC;&#x2122;s fascination with rails reportedly began in Greece where there is evidence of a railway system 6 km long. The Diolkos wagonway existed in 6th century BC. The carriages, which ran in grooves, were propelled by manpower. Fast forward to present day Asia, Japan is widely believed to be the birthplace of regular, high-speed railways. A country with a myriad of rail systems from the modern bullet train to the quaint Enoden of yester year, they run throughout the island nation, driving the country. Major railways add up to some 12,400 miles (19,956 km), according to Japan Rail, which operates most of it. Developments West Of Japan Other parts of Asia are also 64â&#x20AC;&#x192; industrial automation asia | June/July 2009
following suit by developing high-speed rail systems. A report from Xinhua News says that the Chinese government has started construction of the BeijingShanghai high-speed railway, with a designed speed of 350 km/h. The 1,318 km long railway line, upon its completion in five years, will cut the journey time between China's capital of Beijing and its eastern financial hub of Shanghai in half, to five hours. It will also lift the one-way transport capacity to 80 million passengers and more than 100 million tonnes of cargo annually, said the Ministry of Railways. With an investment of RMB220.9 billion (US$31.6 billion), the railway is the most expensive construction project in one lump sum China had since 1949. In addition, the country's first
domestically produced train, able to reach 350 km/h, rolled off the production line. The eight-carriage train, with a streamlined body made of light aluminium alloy, can carry 557 passengers. Elsewhere in countries like South Korea, Taiwan and Singapore, there are extensive train and subway systems, which are expanding as well. For instance in South Korea, the authorities are currently building an extension to the 40.3 km high-speed rail connecting Gimpo Airport and Incheon International Airport. According to Gale International, a real estate development and investment firm headquartered in New York City, the second railway line will connect Gimpo Airport to Seoul Station and is scheduled to open in 2010.
Nearly WON3 trillion (US$2.3 billion) from the private sector and WON1.1 trillion of taxpayer money is being invested in the railway projects, with the IncheonGimpo railway alone having taken WON1.8 trillion. In Singapore, the development and construction of the Circle and Downtown line are well underway, with an approximate S$1.1 billion (US$745 million) invested for the downtown line alone. These major investments will no doubt trigger other supporting industries like the metalworking industry and the steel producers as tracks lengthen and more trains are needed. Giving The Right Signal Signalling is of utmost importance especially today where trains travel in high speeds and carry heavy load. Companies like GE Transportation can benefit from major projects in China or throughout Asia. They have products to give freight, passenger and urban transport operators a set of control, supervision and communication capabilities to optimise their networks and assets. T h e s e s y s t e m s i n c re a s e capacity and velocity without
Engineers continue to push the envelope in terms of speed
The rail system in Singapore is expanding with the Circle and Downtown lines
requiring new investments in infrastructure. A big part of signalling is also lighting. The company’s LED retrofit kits provide more light at all viewing distances and have longer service life and mean time between repairs. The polycarbonate lenses have a life expectancy of 100,000plus hours. Grounding The Plane Trains are getting faster to a point they are real competitors to airplanes plying the same route. As advancements in aviation are well documented with the A380 aircraft taking most of the plaudits, highspeed trains are slowly inching faster in their quest to usurp the coveted throne to become the new darling of transportation. People belonging to the metalworking family can take heart that both industries generally use aluminium alloy to build their machines and competition between the two will indeed be good news. Aluminium-alloy trains were developed to realise production of the rolling stock with corrosion-free materials. It has one-third specific gravity and equal strength of steel. They are considered ideal for the materials of rolling stock as they have benefits like long-life, lightweight, and maintenance-free traits. Away from the relentless
pursuit of higher speed, other developments also include noise reduction. Especially with the series 700 Shinkansen train (Bullet Train), large-scale extrusion with double-skin structures are built to achieve that. Floating Trains? The quest for high speed is possible by eliminating friction and vibration. In order to accomplish that, magnetic levitation (Maglev) technology, on which magnetic power is used to levitate the vehicles, before being propelled by linear motors has been developed. According to Shanghai Maglev Transpor tation, the electromagnetic principle adopted for the Maglev train was put forward in 1922 and was subsequently awarded a patent in 1934. But thereafter this technology remained in a state of ‘something existing only on paper’. The designed speed per hour reaches as high as 500 km, while the actual running tempo is 400-odd km. As rail systems expands in Asia in terms of size and speed, there is potential galore for the metalworking industry to tap into this niche market and go on its very own high speed run.
