Single-ferrule fittings

Brennan Industries now offers single-ferrule instrumentation fittings.

The single-ferrule fittings are available in sizes ranging from 1/16 to 2 inches. The fittings are available in brass and 316 stainless steel.

The single-ferrule fittings feature a design that makes incorrect installation difficult and makes incorrect assembly less likely because there are fewer pieces involved. The single-ferrule design is ideal for applications under high vibration or pulsation.

“The single-ferrule fittings are preferred by some customers over the double-ferrule style fittings,” said Bill Jarrell, vice president of sales and marketing. “We have responded to our customers who were requesting a single-ferrule fitting.”

Power quality meter

The latest smart modular power analyser from Carlo Gavazzi introduces a new performance level within the company’s proven energy management range. The WM30-96 offers enhanced faster communications for building automation networks, along with superior functions such as load monitoring measurement and comprehensive alarm management; all in a compact plug-and–play modular format that streamlines installation and simplifies inventory management.

Starting with a base unit that provides the display, touch-panel, power supply and measurement inputs, users can then add up to three slimline modules to the rear for alarms, pulse outputs, analogue I/O and data communications interfaces. It’s the first modular power analyser to provide BACnet-IP communication.

Applications run from cost allocation and control, through complex cost and power analysis, to advanced energy and power analysis for solar energy and power generation.

A mono LCD occupies much of the base unit’s 96mm-square frontage. All necessary information is available at a glance on the front panels customisable home page, which is readily configured by the user. Values of actual vs. installed power are displayed continuously to provide immediate alerts to potential power overloads.

The WM30-96 offers high accuracy for energy metering together with 10 digits for total energy counting, ensuring ideal performance for medium and high voltage applications. High contrast, white backlighting and wide viewing angles ensure that information is easy to see from any position.

Touch panel technology gives major advantages over traditional push-buttons for selecting from the four main variable areas: energy metering; current-voltage-frequency metering; power and power-factor metering; and harmonic analysis. FFT harmonic analysis is performed up to the 32nd harmonic (current and voltage), ensuring dependable measurements for load control and alarming. There are four freely configurable virtual alarms and a real time clock function is built in.

The base unit is powered by a universal 18 to 60 VAC/DC or 90 to 260 AC/VDC supply and front protection is provided to IP65, NEMA4x and NEMA12 standards. Carlo Gavazzi’s use of advanced component technology has resulted in space-saving behind the panel of up to 30 percent compared with competing analysers.

Whilst the base module alone acts as a simple monitoring device, the meter is completed by stacking low-profile modules on the rear of the base unit. Up to three flat modules can be added: one each of type A, B and C.

Dual channel relay output (SPDT) and dual channel static output (AC/DC Opto-Mos) modules are type A. Type B designates analogue outputs including a dual channel 20mA current module and dual channel 10V DC voltage device. Data communications facilities are added using type C modules: currently available are a fast RS485/RS232 serial port, Modbus over Ethernet TCP/IP interface and uniquely a BACNet-IP port. Depth behind the panel is just 50mm with a single option module.

As with other Carlo Gavazzi energy meters and analysers, the WM30-96 carries CE marking and UL certifications.

Catalogue on CD

Rittal have released a CD of their popular catalogue for Electronics Enclosures and associated products.

Customers faced with the size of Rittal’s Handbook 32, were demanding a more portable look up system which complemented the information available on the website.

Packed with details on everything from Backplanes to Power Supplies and with some base systems included to give designers a head start, the catalogue includes all of the Ripac branded Subrack ranges, both as kits and individual parts, as well as Desktop Cases and Rack Cases.

Touch sensors replace switches

Further to its recent announcements of licensing agreements with Nissha and Samson Electro-mechanics for 3D input technology for mobile phones, Peratech Limited has announced that YFM Group managed Partnership Investment Finance has invested £1.1 million into the Company. This will be used for further research and development into Peratech’s award-winning, patented Quantum Tunnelling Composite (QTC) technology for touch technology solutions, as well as growing the company’s highly successful sales into overseas markets.

“We are really excited by the huge potential of Peratech and its technology,” says Mark Winderbank at YFM Group, which is the most active VC investor in UK SMEs. “Peratech’s recently announced license deals with major international companies Nissha and Samsung Electro-mechanics demonstrate how QTC can open up exciting new ways of doing things. We are proud to be able to support a fast growing British company with a truly unique technology that has a tremendous world market. Of all the possible investments that we have looked at recently, Peratech stood out because of the strength of its innovative technology and huge growth potential.”

The key to QTC’s success is that it enables traditional, old fashioned switches to be replaced with ultra reliable QTC versions that offer additional features such as no contacts to wear out and no air gap to be contaminated with water or dust. Moreover, because QTC is force sensitive, it opens up a whole new range of applications where the current flowing is directly proportional to the pressure applied. This enables a new category of touch sensitive, human machine interfaces to be created with a completely new three dimensional aspect. For example, the width of a line being drawn electronically can depend on the pressure applied, which is an ideal feature for Asian and Chinese characters, or pressing harder moves faster down into a menu structure on a mobile phone.

“In these financially challenging times, it is a real testament to both the QTC technology and the team behind it to have received funding of this level,” adds Philip Taysom, joint CEO of Peratech. “The Company has invested significant R&D efforts to understand this new class of material science that it has invented. We are now at the stage where its ability to add value and completely new innovative features, which provide significant commercial advantages, are clearly demonstrable as can be seen from the licensing deals that we are closing with Tier 1 international companies.”

    Viewing hundreds of process variables

    Curvaceous Software's Visual Explorer 2.5 (CVE 2.5) is the only programme that lets you view hundreds of process variables and their alarm limits in a single graph and its new features in Alarm Management have got the process industry talking.

    Ian Nimmo, Founder and President of UCDS Inc and a member of the ITE (CEI) in the UK said: “At a recent conference I saw some outstanding alarm work by Dr Robin Brooks of Curvaceous Software Ltd. This was the first alarm management paper in the last ten years that got me excited as he explained how alarms can achieve management objectives, how to understand alarm settings in a new light and how to change them correctly.”

    Alarm Rationalisation & Management has been wholly revolutionised in CVE 2.5 with new Consistent HiLo Alarm Limits & Alerts, which work from process history data rather than alarm log data. CVE 2.5 provides instant feedback on Annunciation Rates and Standing Alarm Counts and delivers minimum time savings of 20% to perform Alarm Review meetings as well as delivering ongoing reductions. Curvaceous won the EPSC Award for the invention of Consistent Alarms in 2003.

    Dr Robin Brooks, Managing Director of Curvaceous Software said: “We’ve won awards for our work in Alarm Management and are delighted at the overwhelming response our improved Alarm Management features in CVE 2.5 have received from the oil and gas, pharmaceutical and chemical industries.”

It enables a user to see, understand and reduce variability in their processes and delivers significant cost savings and business efficiencies.

    Ian Nimmo will be giving a keynote speech at Curvaceous Software Limited’s TAP Forum Customer Event, 24 – 26th March 2010.

    Steel production managment made efficient

    GE Intelligent Platforms has been selected by Qatar Steel to provide a complete production management solution designed to improve operating efficiency through a reliable and optimum production process. The overall contract, worth $2 million, features GE’s suite of Proficy® software including Plant Applications, Historian, iFIX and Portal rolled out in a phased format led by a significant pilot project.

    The Proficy software solution covers design and implementation for data collection from multiple systems including material storage, handling and control, direct reduction furnaces, electric arc furnaces, ladle furnaces, continuous casting machines, bar rolling mills, the plant’s Quality Control Centre and Enterprise Resource Planning (ERP) system.

    “This new solution will enable Qatar Steel to better monitor and control material flow, production processes, equipment performance, operator activities, and other Key Performance Indicators (KPIs) at various levels of the organization,” said Erik Udstuen, Vice President of Software & Services for GE Intelligent Platforms, “It will also be able to aggregate data for top management reporting and decision-making.”

    The Middle East is expected to produce more than 60 million tons of raw steel by 2010 and Qatar Steel will be a forerunner in this production. The company is regarded as an innovator and has been instrumental in the development of the region since 1978 when production began.
    “The GE team engaged us well and has taken the time to understand our requirements and made every effort to demonstrate the capabilities of their technology to meet our demands in Qatar,” said Sheikh Nasser Al Tani, Managing Director of Qatar Steel.

    “The decision was made after an exhaustive evaluation process including current and future requirements analysis, return on investment scenarios and implementation methodology,” said Malek Hamdieh, Manager IT for Qatar Steel.

    The extensive pilot project tackled the plant’s biggest problem area –- tracking and optimizing the raw material input to the plant. The previous system was based on large quantities of hand written material that was difficult to control and use making information analysis slow and prone to error.

    The planned implementation will include Proficy iFIX providing the tools for monitoring the process from the control room, and Proficy Portal providing web access to the analysis tools. The PACSystems RX3i will be used to automatically collect and bring plant process data to the Proficy software where no such systems existed in the older sections of the plant.

    “The Proficy Software enables us to deliver on work simplification, elimination of errors and delays in providing real time information with the context for better and faster decisions,” said Yousef Al Emadi, Qatar Steel Production Manager.

    The pilot project took two months to develop and install. The implementation of the Proficy Software solution is expected to be complete in 14 months.

    Industrial wireless survey results

    The Wireless Industrial Networking Alliance (WINA) has announced results of its first End-Users survey on the application of wireless technology in the automation industry at the ARC Forum in Orlando, Florida.

    “Given today’s economic outlook we wanted to go directly to the end users of various industries to establish a benchmark,” said WINA president, Steven Toteda. (Shown at left discussing ISA 100 Wireless Standard at ISAExpo'09) “We posed questions to our large member base about what, in their view, the major issues and contributing factors in wireless implementation are and what the future may hold for wireless at their sites.”

    According to WINA, survey results showed that the process automation industry overwhelmingly agrees there is a clear shift toward preference for wireless field devices, with only 5% believing industry will not embrace wireless. Illustrating this point, nearly 40% of respondents expect wireless devices to make up 20% or more of their field devices by 2015 and of this group, over 50% believed wireless devices would account for 30% or more in the same time frame.

    “Heavy industry moves slowly, but very methodically,” explained Toteda. “The growth of wireless devices from the current average of 5% to that of between 20-30% in five years represents a staggering advance for wireless especially when you consider the size of a refinery or water treatment plant that may have 50,000 sensor points over several square miles,” he added.

    Security concerns remain the number one barrier among those who had not yet implemented wireless, with 50% of survey participants believing that wireless solutions were less secure than wired. On the flip side however, within those industries surveyed that had more experience with wireless, Oil & Gas for example, respondents most frequently perceived wireless to be as secure or more secure than wired.

    Predictably, security and robust industrial design topped the list of qualities considered vital when users conducted side-by-side comparisons. Standards-based solutions were also rated as most or very important by 40% of respondents. Surprisingly, however, was that 55% of those surveyed believed a brand name product was of little or least importance.

    According to Toteda, there is still a lot for suppliers to do to educate end-users on the security benefits of wireless. “I look at these results and am impressed by two things,” he states. “First, that the industry as a whole has failed to adequately address the misconception that wireless security is not as effective as hard wired – the truth is, wireless is far more secure because of the use of strong encryption technology and network controls that eliminate unauthorized devices from being on the network. Second, the fact that according to our results, decisions are not being made based on brands that may be already installed. This may imply new market share gains for existing vendors moving aggressively, or an opportunity for new vendors to emerge.”

    The results were presented at a lunch at ARC’s Fourteenth Annual World Industry Forum at the Rosen Center Hotel and Conference Center in Orlando, Florida. Harry Forbes, ARC Advisory Group, introduced the industry expert panelists: Steven Toteda, President of WINA and VP GM, Cooper Wireless; Dr. Penny Chen, Principal Systems Architect at Yokogawa's Industrial Automation Global Strategic Technology Marketing Center, Yokogawa; Stephen Lambright, Vice President, Apprion; David Kaufman, Director of Business Development for Honeywell Process Solutions, Honeywell, and Hesh Kagan, Process Systems Director of Technology for New Business Development, Invensys.

    Warehouse automated handling

    Holding and moving heavy metal tubes is not an easy task for automation engineers. Holding and moving heavy metal tubes... in narrow rows of automated warehouses... at high speed... is even... worse! Tecnorulli decided to go wireless for such types of applications.

    The wireless option faced issues due to the environment itself (everything is made of metal in the warehouse) and more over, the moving parts, the carriages which are navigating through the aisles for depositing and/or taking material from the shelves and rows, are themselves made of metal. In short, the RF environment is some of the worst you can imagine for robust, safe, and reliable wireless applications. Nevertheless, they wanted to overcome the challenge and decided to go wireless , with one objective: improve quality and response time to better serve their customers. ProSoft Technology's RadioLinx industrial radios were the key to resolving the communications difficulties Tecnorulli was facing in its automated warehouse.

    The Italian company Tecnorulli is a leading manufacturer of rollers and machinery for conveyors. Located in Verona, Tecnorulli has been producing rollers and machinery for conveyors for 35 years . Constant technological development and fast, timely response to its customers´ needs, and great production flexibility are the mainstays of Tecnorulli corporate strategy. To that end, an automated warehouse handling system was crucial for the global performance.

    Over time they have gradually acquired the experience and specific expertise that have brought it to the top in that trade sector. In fact, the company produces both machinery designed to withstand the harshest working conditions (quarries, mines, marble working industries, sugar factories, salt works, road-building machinery, foundries, cement factories, etc.) and also high technology products used in the most modern automated factories (mechanical conveyor lines, bottling plant, packaging, pallet loading, pharmaceuticals, chemical industry, etc.). Tecnorulli also manufactures clutched and idle wheel rollers, which are specially designed to ensure reliable working even under extremely hostile conditions. Its offer is completed by its PVC and polyamide series of products which, for medium-light loads, combine great flexibility of application, complete non-toxicity, silence and absence of sparks, with the resistance to atmospheric agents typical of galvanised steel rollers.

    The importance of communications

    As the warehouse automation involved moving chariots, an industrial radio communication system was necessary. After an unsuccessful attempt with a previous option, Tecnorulli found a reliable solution with ProSoft Technology: "As you can imagine, production downtime is a big problem in our business," Tecnorulli plant Supervisors explain. "For a long time we have been struggling with a problem in our automated raw materials warehouse. We had to transport metal tubes in a perfectly safe way. We contacted ProSoft Technology to see if we could bring in industrial radios. Their partner in Italy, ATTI, based near Perugia in Ponte San Giovanni, installed the radios and the issue was very quickly solved."

    "Our problem was that we were unable to get the two machines in the warehouse to interface properly. We had problems connecting these two machines, but thanks to the use of ProSoft Technology RLX-FHS radios we were able to solve the issue and eliminate warehouse blockages. We haven´t had any more problems since we installed the ProSoft industrial radios and the workflow has undoubtedly benefited."

    "To help our customer in their choice, we may in some case lent them the industrial radios for a month in order for them to see first-hand that our solution would perfectly fit with their needs," explains Giuseppe Vencesclai, CEO of ATTI.

    Ease of use and reliability
    In this case, three ProSoft Technology RLX-FHS radios were installed in Tecnorulli warehouse. These radios are designed to reduce the costs of engineering and installing serial (in this case, but could be Ethernet) networks for industrial automation in the most difficult environments, such as a warehouse for metal parts.

    "Our customers use to report that ProSoft Technology´s wireless solutions offer very high reliability and are very easy to implement," explains Aurélien Fabre, Business Development Manager for Italy at ProSoft Technology, "and these solutions largely contribute to great return on investment."

    This new generation of industrial radios is extremely easy to use and ProSoft Technology particularly worked on the sensitivity of the receivers and the filtering algorithms. End users can thus count on more effective operation in environments where the levels of interference are high and they can also set the radios a greater distance apart.

    With the ProSoft Technology Frequency Hopping radios (FHSS), data transfer rates between serial interface devices range from 19.2 Kbps to 230 Kbps (up to 3,000 Mbps for Ethernet version). These RadioLinx radios operate in the 2.4 GHz or 900 MHz frequency bandwidths (depending on country regulation). The frequency-hopping technology of these radios gives wireless networks a very high level of security, almost total immunity to interference and a very wide range (5-10 km in Europe, and up to 24 or 48 km in North America, according to authorized emitted power which depends on country regulation).

    ControlScape, an easy-to-use software application handling network configuration and advanced troubleshooting, is supplied free of charge by ProSoft Technology. This software monitors variables such as signal force, data transmitted, number of networks connected, etc., to help end users install and maintain their own network.

    Preserving priceless art!


    Michell Instruments has loaned two instruments to the National Needlework Archive (NNA) (GB) to help preserve an iconic mural. Designed by Constance Howard for the Festival of Britain in 1951 "The Country Wife" is considered to be one of the 20th Century’s most important textile works. However, after nearly 60 years, the mural is in urgent need of restoration work to ensure its survival.

    Part of the preservation process involves storing the work in an anoxia bubble where levels of oxygen are maintained at 1% with a relative humidity of less than 50% at 23°C. In order to monitor this environment, the NNA is using two of Michell’s instruments: an XTP600 Oxygen Transmitter and a DM509 RH handheld device.

    The XTP600 uses the highly stable thermo-paramagnetic sensing technology to measure levels of oxygen in gases. With its high reliability and low maintenance requirements it is ideal for applications such as this where an instrument is needed to monitor conditions over a long period of time.

    The DM509 is a versatile hand-held relative humidity and temperature transmitter. It is not only lightweight and portable, but also easy to operate. This is a vital feature for the NNA staff who want to focus on the restoration work rather than the instrumentation.

    The restoration project on this and other textiles is planned to take several years to complete, with the instruments on loan from Michell helping to maintain the environmental conditions throughout.

    Vision capabilities

    National Instruments has announced the addition of machine vision capabilities to their CompactRIO and NI Single-Board RIO hardware devices that provide engineers with an integrated measurement and control platform for industrial and embedded systems. With this integrated platform solution, CompactRIO becomes one of the only programmable automation controllers (PACs) on the market to perform vision tasks, providing a more efficient, all-in-one design with a smaller physical footprint and less system complexity.

    With the addition of machine vision, engineers can use CompactRIO and NI Single-Board RIO devices in a variety of advanced measurement and control applications. It is an ideal solution for autonomous and semi-autonomous robotics applications for obstacle avoidance, pattern recognition and simultaneous localisation and mapping (SLAM), where advanced control and vision functionality are required. Industrial surveillance applications served include both machine condition monitoring and critical vessel monitoring, when connectivity to infrared cameras is vital. Finally, the real-time OS and integrated field-programmable gate arrays (FPGAs) used with both CompactRIO and NI Single-Board RIO eases the process of FDA validation for embedded medical devices.

    Machine vision systems consist of two parts: image acquisition and image processing. To acquire images, NI vision acquisition software has expanded to support Internet Protocol (IP) cameras, including those from Basler Vision Technologies. In addition to native IP camera support, National Instruments Alliance Partner moviMED has released the AF-1501 analogue frame grabber for NI C Series products that can acquire monochrome images. To process images, engineers now can program and deploy image processing libraries to CompactRIO and NI Single-Board RIO deployment targets with LabVIEW 2009 graphical system design using the NI Vision Development Module 2009 software, which contains hundreds of image processing and machine vision functions.

    "At our Global Technology Development facility, we are always looking to optimise the size, speed and reliability of our manufacturing machines,”
    said Ben Engelen, Senior Project Eengineer for Vision and Measurement at Philips GTD Mechanization. “The CompactRIO platform provides the high-speed determinism we need for efficient and precise component placement. The new MoviMED AF-1501 frame grabber module helps us integrate video feedback into the same platform and fully automate the entire process.”

    Engineers can add vision capabilities to the following CompactRIO and NI Single-Board RIO controllers: NI cRIO-901x, NI cRIO-902x and the NI cRIO-907x and NI sbRIO-96xx systems.

    1st among signal conditioners

    We cover the "best-of" rankings of the excellent American publication "Control" as the recipiants tell us. Although this is an American publication it does like most publications (including Read-out) have a web presence called ControlGlobal.

    Moore Industries has been ranked first place in Signal Conditioners by Control Magazine Readers’ Choice Awards 2010. The top technology category rankings represent end-user sentiment, as the 2010 Control Magazine Readers’ Choice Awards were derived from the opinion of over 1,000 process automation professionals.

    Support team recognised for excellence

    Invensys Operations Management's Wonderware technical support organization has been honoured with the 2009 STAR Award for service excellence from the Technology Services Industry Association (TSIA), the industry's largest services association. The Wonderware support organization received the STAR Award for Service Excellence in Mission Critical Support - Software - SMB.

    "At Invensys we recognize that superior support is an essential ingredient in all of our solutions, and providing world-class support requires an uncompromising commitment to excellence," said Phil Couling, global marketing manager for support and services at Invensys Operations Management. "This award is a significant acknowledgement of the service-oriented culture that Invensys and the Wonderware® brand have built to surpass our clients' expectations, even in the most demanding support environment. It also means that our customers can continue to look forward to new innovations as we introduce more support offerings and choices."

    The honour recognises Invensys Operations Management for providing technical support in mission-critical environments where system up-time is imperative, typically for enterprise customers. Technical support is an important part of minimising downtime in any business or industrial operation. Since its inception in 1990, the prestigious STAR Awards recognise technology companies that display exceptional leadership, innovation and commitment in service excellence.

    "The STAR Awards are recognised throughout the industry as one of the highest honours for service and support organisations," said Stephen Smith, chief financial officer and chief information officer at TSIA. "This award acknowledges that Invensys and its Wonderware support organization have been honoured by its peers for providing world-class support as one of the best in the business."

    Gas analyser radically enhances safety & security

    Quantitech is to demonstrate a highly advanced portable gas analyser at Counter Terror Expo 2010 (14/15 April 2010) - the Gasmet Dx-4030.

    Employing FTIR technology, the analyser is already helping professional investigations in a wide variety of applications including those for which it is not possible to determine, in advance, the gases that are likely to be encountered.

    The instrument is the World’s first truly portable FTIR multicomponent gas analyser, enabling operators to measure multiple components simultaneously, including Toxic Industrial Chemicals (TICs), Chemical Warfare Agents (CWAs) and almost anything else.

    In the past, field-use instruments for the detection of toxic gases have sacrificed analytical performance for the sake of usability. As a result, many portable instruments have merely provided data that is indicative and non-specific, whereas analytical instruments have been difficult or impossible to operate in the field.

    The Dx-4030 is able to measure any organic or inorganic gas with the exception of diatomic gases (O2, N2, etc), noble or inert gases, and H2S.

    Quantitech’s Dr Andrew Hobson, said: “The unique Dx-4030 provides accurate real-time multi-gas analysis within seconds of powering up; it is ideal for emergency response to any situation that calls for rapid reliable gas analysis. The robust battery powered back-pack system can be operated without the need for specialist training and analysis of saved infrared sample spectra allows result validation and unknown gas identification."

    An example of the applications for which the Dx-4030 can be employed is the testing of cargo containers at ports and airports. Cargo containers, wooden packing materials and foodstuffs are fumigated by shipping companies to control the spread of pests and micro-organisms. Fumigant gases are toxic and containers are therefore monitored for health and safety purposes on arrival at each new port or destination. In addition, products shipped in containers can release VOCs from solvents and glues used in the manufacturing process, and their concentration may accumulate in the confined space of a container.

    Dr Hobson explains: "Existing portable instruments are limited in the range of parameters that they are able to measure, so it is often necessary to take grab samples for subsequent laboratory analysis. In contrast, the DX4030 portable analyser is uniquely able to measure almost anything, providing fast measurements for customs inspectors and shipping company staff."

    FTIR offers major advantages over other techniques because of its specificity and lower susceptibility to interference gases, however Dr Hobson says, “From an occupational safety perspective, it is extremely important to be able to detect hazardous gases as quickly as possible and by avoiding the cost of laboratory analysis, operational costs are reduced considerably.
    "From a security perspective, the ability to measure TICs and CWAs with a portable instrument offers enormous advantages over traditional techniques."

    Visitors to 'Counter Terror 2010' at Olympia, London on April 14-15, can view the DX4030 in action on the Quantitech stand (A40).

    Industrial networking for automation

    Silica is appearing at this year’s Embedded World fair in Nuremberg (March 2nd – 4th, 2010) entirely under the banner of “Networking for automation systems”.

    There will be a live demonstration of controlling a high-stack shelving system based on EtherCAT (Ethernet for Control Automation Technology) standards. The high-stack shelving system is used as an example to show how many things industrial Ethernet can do.

    The system was designed, built and programmed entirely by SILICA’s applications engineers. All the specialists involved in developing it will be on hand and available to visitors for first-hand information throughout the fair.

    The system is controlled via a process control system running as software under Microsoft’s Windows Embedded Standard on an Intel® Atom™ platform which serves both as EtherCAT master and industrial PC. The model’s sensors and actuators are interfaced via a slave module, demonstrating how the EtherCAT standard is realised with an FPGA core on a Xilinx FPGA.
    Galvanically separated interfaces linking the 3.3 V and 24 V domains use Infineon and STMicroelectronics modules.

    Both the high-stack shelving system’s input and output stations have RFID readers implemented with NFC chips by NXP and barcode readers which analyse camera signals using a Renesas microcontroller. Readout data is sent to the PLC in the industrial PC and processed there. A live image of the demo is sent from a CCTV camera using a Blackfin processor by Analog Devices.

    SILICA’s appearance at the fair reflects its total solutions and technical support strategy: its own application developed in-house enables specialists to deal with typical problems and the complex applications involved directly.

    SILICA is at Halle 12, Stand 241, and is also represented as co-exhibitor on Microsoft’s Stand 11-318.

    New controller

    The JetControl 940MC was introduced by Jetter at the SPS/IPC/DRIVES trade fair in Nuremberg. It has been mainly developed for applications comprising a great number of motion systems for quick cycles and high dynamics. These are, for example, path control and interpolation applications, as well as technological functions like screw-capping, electronic gearing, winding function, etc.

    Compared to the already obtainable controllers of the JetControl series, the 940MC is expandable by even more peripheral and axis modules. It is programmed by means of the
    high-level language JetSym STX which is able to multitask. This is the main difference between the classical PLC controllers and the JetControl 940MC.

    Further, various interfaces (Ethernet, CAN, serial, USB) are available. The standard Ethernet TCP/IP is applied as communication network. This way, IT services, such as HTTP, FTP, and e-mailing, which the users have always known from JetWeb, can be implied.

    IS communication standards


    CAN in Automation (CiA) has released the CiA 102 and 103 CAN physical layer specifications for industrial automation respectively intrinsically safe capable communication as Draft Standards. The free downloadable CiA 102 specifies eight bit-rates for CAN high-speed networks (from 1 Mbit/s to 10 kbit/s) compliant with ISO 11898-2 or ISO 11898-5 (with low-power capability). The specification also includes some guidelines for the physical medium attachment (PMA) sub-layer, and the medium dependent interface (MDI) sub-layer. This covers device and system design hints. The updated specification is also the base for CANopen networks using high-speed transceiver chips.

    The CiA 103 specification describes a framework for CAN high-speed networks used in explosive environments. It has been developed in cooperation with CPAC (Center for Process Analytical Technology) at the University of Washington, Seattle (USA). The intrinsically safe CAN physical layer specification requires 3,3-V transceiver chips and micro-controllers with on-chip CAN modules. Sensor manufacturers supplying for gas chromatographs have implemented the framework firstly. Devices compliant to CiA 103 received already approvals for hazardous area class 1 by North American and other authorities.

    The specifications are downloadable from CiA’s website.

    Heart activity signal processor

    At the International Solid State Circuit Conference (San Francisco CA US), imec and Holst Centre report an analog-signal processor ASIC (application-specific integrated circuit) – in short ASP - that reduces the overall power consumption of an ambulatory heart activity signal monitoring systems by more than 5 times. This is a major step towards autonomous wireless sensor systems, which constantly monitor the patient’s health for diagnosis of chronic illness.

    In today’s biomedical wireless sensor systems, a lot of power consumption is wasted in the DSP (digital signal processor) or radio by continuously processing biopotential signals (e.g. ECG or electrocardiogram), or transmitting raw data over the wireless link. And, today’s ambulatory biomedical sensor systems also suffer from motion artifacts which affects the robustness of detection algorithms and demands even more processing power.

    The innovative ASP, developed within imec’s and Holst Centre’s HUMAN++ program, uses an adaptive sampling scheme based on activity detection. This reduces the amount of data which needs to be processed by the DSP or transmitted by the radio. By preprocessing the signal, a simplified DSP can be used for accurate R-peak detection resulting in lower power consumption of the DSP. Motion artifacts are detected by continuously monitoring the electrode-tissue impedance. The impedance monitoring can also be used for ensuring signal integrity by continuously checking the electrode connectivity.

    The ASP has a record low power consumption of only 30µW operating from 2V. It consists of an ECG readout channel, two quadrature readout channels for continuous-time monitoring of electrode-tissue impedance, and two quadrature readout channels for tracking signal fluctuations in a specific frequency band. The ASP also includes an activity detector that senses the frequency content of the ECG signal and adapts the sampling rate of the integrated ADC (analog to digital convertor) for the digitization of the ECG signal. The ASP stage reduces the power consumption of the DSP and wireless transmission by 11 and 6 times respectively. This results in an overall system power dissipation below 300µW for the complete wireless heart activity signal monitoring system which is more than 5 times more power efficient than its predecessors. This power budget also includes the additional functionality of continuous-time electrode-tissue contact impedance measurement.

    “Within the Human++ program, imec and Holst Centre develop solutions for an efficient and better healthcare. Self-powered intelligent body area networks with wireless sensors promise to be a solution for more comfortable healthcare systems. This breakthrough is a major step towards constant ambulatory monitoring of people using energy harvesting, which increases the comfort level of patients and is a cost- and time-efficient alternative for current monitoring systems;”
    said Bert Gyselinckx, general manager imec the Netherlands at Holst Centre.

    Industry can get access to this technology by joining the Human++ program as research partner or by licensing agreements for further product development.

    Automated independent backup system

    SIS-TECH now has the DIAMOND-SIS automated independent backup (AIB), a low-cost, standalone safety instrumented system (SIS) that backs up current process control trip logic and meets the requirements of IEC 61511. The system includes an IEC 61508 logic solver that is functionally independent from the process control system, supplements existing logic, and meets all appropriate safety standards.

    This system provides high integrity and process reliability. It is available in single, dual, and triplicated channel configurations with on-line diagnostics, testing, and maintenance capabilities. The single and dual channel systems are acceptable for SIL 2, while the triplicated channel system is certified by Factory Mutual to SIL 3. This means that it can meet the fault tolerance and PFavg requirements of any application.

    With its 5A output rating, the system can de-energize multiple final elements including motor control circuits and/or solenoid operated valves. Local or remote manual reset ensures controlled process re-start after shutdown.

    It is particularly useful with legacy control systems that do not meet current SIS standards. Typically, during the early days of digital control, users implemented safety logic within their process control systems. Today, they do not want to impose SIS requirements or management restrictions within the existing systems.

    Instead, they need an independent backup safety logic system that connects easily to existing plant equipment, meets all safety standards and requirements, and requires no reprogramming of process logic since it fulfills all of those requirements.

    Easier to install and maintain than a Safety PLC
    A single channel DIAMOND-SIS AIB system includes a pre-mounted and wired DIN-rail signal isolator, a Model 340 logic solver, a fuse block, and five terminals ready to accept existing wiring. All components are rated for -30 to 75 degrees C and Class I Div II operation, and meet the mechanical integrity requirements of IEC 61511.

    The system can typically be mounted in an existing DCS marshalling cabinet, and the user wires the logic solver contacts in series with the DCS contacts. The logic solver then independently backs up the trip functionality of the DCS.

    Each DIAMOND-SIS logic solver module can accept virtually any analog input. Its two field adjustable trip points allow the process to be shut down on high and/or low process variables, or to detect an out of range signal fault. The number of inputs and the voting architecture—such as 1oo1, 1oo2, 2oo2 or 2oo3—can be adjusted to meet performance requirements. The process shut-down signal from the logic solver can be sent to both the DCS, and directly to a shut-down device such as a relay or solenoid.

    The installation does not require any reprogramming of the existing DCS. In addition, the installation cost of a system is 80% less than that of an equivalent Safety PLC with the same number of loops. Maintenance costs are also greatly reduced as it’s not necessary to purchase, implement and renew programming software.

    The Safety Requirements Specification, including Safety Integrity Level (SIL) verification documentation, can be supplied as an option. This makes the DIAMOND-SIS AIB the perfect packaged solution to address low I/O SIS needs, and the low cost alternative to safety PLCs.

    Freezer validation system

    The weather has been extraordinary cold in many Northern Hemisphere regions this winter so the picture accompaning this release will summon up many memories.

    MadgeTech has released their ULT90, an ultra-low temperature freezer validation system. It can be used for validation, mapping, stabilization studies and temperature surveys.

    The ULT90 provides a complete temperature mapping and validation solution for freezers of all sizes and configurations. It includes Cryo-Temp data loggers, a USB docking station, MadgeTech’s Secure FDA 21 CFR Part 11 software and IQ/OQ/PQ validation protocols. The ULT90 can be fully customized to include user-specified quantities of each item in the system to accommodate specific applications.

    The Cryo-Temp data logger can measure and record temperatures as low as -86°C and is splash resistant. To provide data integrity, and meet the requirements of FDA 21 CFR Part 11, the secure software includes electronic signatures, access codes, a secure data file and an audit trail.

    For large freezers the software can graph datasets from multiple loggers to show variances in different parts of the freezer. This can reveal air stratification, hot spots and anomalies in chilling systems.

    The ULT90 is available with 9 Cryo-Temps (ULT90-9), 15 Cryo-Temps (ULT90-15) or the system can be completely customized to meet the validation needs of a specific freezer (ULT90-Custom).

    Agreement for technologies & services!

    Emerson Process Management has entered into a 5-year Global Framework Agreement (GFA) with Shell to serve as a Main Automation Contractor (MAC) on future capital projects globally.

    Under the Agreement, Emerson will provide project and support services for Main Automation Systems, including Distributed Control Systems (DCS) and Safety Instrumented Systems. The contract also provides for ongoing maintenance of existing systems, plus the supply of new systems for Brownfield and Greenfield facilities. While Shell has utilised a MAC strategy in its Downstream businesses for years, the Company is expanding the concept to make it a centre-point of an enterprise-wide automation strategy.

    “This Global Framework Agreement marks a completely new approach within Shell,” said Nick Curley, upstream automation portfolio manager for Shell. “It is a long-term, competitive, collaborative, performance-based relationship that will facilitate the delivery of considerable value to both parties. We will be looking to emulate this approach in many other key global categories in the future.”

    “This new agreement will put Emerson in a position to substantially broaden its Main Automation Contractor footprint within Shell,” said Ronaldo Marques, general manager, equipment, for Shell’s Enterprise Categories & Suppliers division. “For the first time in history, Emerson will have full and open access to all Shell business units - Upstream, Downstream, Wind, Power and Biofuels - plus affiliated Joint Ventures.”

    "We have enjoyed a solid relationship with Shell for decades," said Steven A. Sonnenberg, president of Emerson Process Management. "This Global Framework Agreement symbolises the shared belief our two companies have that early engagement, clear objectives and collaborative work practices result in more predictable success for projects and operations. We are thrilled to be selected by Shell for the role of Main Automation Contractor."

    South African entity wins leadership award

    Invensys Operations Management, a global provider of technology systems, software solutions and consulting services to the process and manufacturing industries, today announced that one of its key ecosystem partners, Wonderware Southern Africa, has received the 2009 Frost & Sullivan Market Leadership Award for its success in the South African manufacturing execution systems (MES) market.

    According to Frost & Sullivan, Wonderware Southern Africa "has continued to demonstrate excellence in providing MES products of the highest quality, a supreme customer service and unprecedented value to a broad spectrum of end-user sectors. These factors have helped Wonderware to firmly establish itself as the leading supplier within the South African MES market, supplying products to end-user sectors that include the metals, minerals and mining, chemicals and petrochemicals, as well as the food and beverage industries."

    "This award is a tribute both to the strength of our partner, Wonderware Southern Africa, and to our MES solutions that are enabling an increasing number of our customers to optimise their entire plant operations in real time and achieve operational excellence," said Giuseppe Caltabiano, vice president, marketing, Invensys Operations Management, Europe, Russia and Africa.

    "We are very honoured to receive such a prestigious award because the way our clients do business continues to change at an accelerated rate. Automation engineers and business IT professionals alike are starting to realise that MES is the vital information link between business and production that gives them the real-time control they're looking for," said Deon van Aardt, managing director of Wonderware Southern Africa. "This realisation is coming about after years of market education and proof of successful implementations in numerous industries and with companies of all sizes. No company can exist successfully without integrating their business and production processes. What we offer is not a new concept. It is a better way of integrating and disseminating knowledge, and therefore real-time control, at all levels of the organisation."

    According to Frost & Sullivan, Wonderware Southern Africa and Invensys Operations Management have been successful for three critical reasons: They address a shortage of skilled engineers and technicians needed to install, control and maintain MES solutions; they educate end users about the benefits of employing MES technologies; and they continually introduce new software packages that enable Wonderware® System Platform and InTouch® HMI solutions to be integrated with MES, enterprise manufacturing intelligence, human-machine interface and SCADA solutions from a wide range of vendors using a single, unified platform. This approach empowers end users to achieve their business goals without abandoning prior investments in automation, process control or information systems.

    "These combined factors make Wonderware Southern Africa the deserving recipient of the 2009 Frost & Sullivan Market Leadership Award in the South African MES market," it concludes.
