Wireless water in Guernsey

The Island of Guernsey goes wireless for water management with ProSoft Technology’s RadioLinx

The island of Guernsey is a British Crown dependency, located in the English Channel, about 30 miles from the north coast of France and 70 miles from the south coast of England. Guernsey Water has deployed a communication network to integrate 40 facilities into a single network. These range from pumping stations and water treatment works to land and office buildings. The ProSoft Technology solution, based on IEEE 802.11n standard, proved to be a reliable, easy to integrate and cost-effective solution.

Generally speaking, wireless networks offer many advantages for a wide range of applications. In this case, the main benefit was to ease the interconnection of remote sites. This is the type of challenging project faced by Guernsey Water, the company responsible for delivering high-quality drinking water for Islanders. In addition, Guernsey Water aims to provide a high level of customer service - therefore an efficient communication network is a key requirement. Remote sites used to be connected through the telephone network to the infrastructure. For a new site, no line was available. Instead of adding a new cabled line, the radio option was considered; two RadioLinx radios were installed on this pilot site for tests and evaluation by Boulting Group. One year later, valuing the positive feedback from engineering, installation and operation teams and having a need for revamping its SCADA network, Guernsey Water decided to deploy a wide network to cover the whole Island.

The benefits of wireless became evident very shortly, since installing a pair of radios is much faster than a new phone line, which requires additional engineering work, e.g. trenches, etc. This is very important for an application in such a location (an island) where being self-sufficient is essential for survival and avoids high expenses!

In addition, the wireless links have revealed high reliability, no communication losses, and higher bandwith despite the weather conditions on the Island. The technology has allowed more efficient remote control over the remote site. The solution provided by ProSoft Technology showed a list of benefits in terms of profitability too: the cost of the pair of radios falls within the range of the fixed phone line rental fee for 1 year – and both the better quality and higher speed of the communication network allow a better quality of service to the user.

The best option for high-capacity wireless networks
All of this was feasible thanks to the ProSoft Technology’s RadioLinx 802.11n industrial radios. These high-technology products provide world-class performance for high-capacity networks, including those in interference-prone locations – typically indoor applications – as they can operate with MIMO (Multiple Input, Multiple Output) technology antennas. The coexistence of multiple networks is guaranteed by means of a combination of 2.4 + 5 GHz bands that offers 3 + 19 non-overlapping channels. They also feature a very high signal sensitivity and range, and come as a single-radio or dual-radio Industrial Hotspot, or single-radio Industrial Client.

In the Guernsey project in particular, 19 Industrial Hotspots have been installed; 2 units for the pilot project plus 17 units (mixing single and dual radios) for the second phase. Some key industrial features of these products are their hazardous location certifications (UL1604 Class I Div 2, ATEX Zone 2 Cat 3), their extended operating temperature range, high vibration and shock resistance, DIN-rail mounting, PoE (Power over Ethernet) and simultaneous client or master/repeater Industrial Hotspot mode. All ProSoft technology products come with a three year warranty and unlimited technical support for the life of the product,

RadioLinx industrial radios are easy to configure and monitor with the RadioLinx Wireless N Discovery Tool. This software tool allows the possibility to view the network topology, assigning IP addresses to radios for configuration, as well as monitoring network diagnostics, updating radio firmware and detecting any 802.11 radios on the network.. Automatic or manual network configuration is user selectable (it can be prioritized or fixed) with self-healing functionality and master redundancy for reliable large networks.

Boulting Group was involved in this project as system integrator. They are renowned for supplying cutting-edge engineering solutions in mechanical and electrical systems and services across a broad range of industries around the world from a single aspect of a project to a full turn-key solution.

“Technology was new for both Boulting Group and for Guernsey Water,” recalls Jonathan Green, Automation Manager at Boulting Integrated Systems “but installation was a success. Not only has it been possible to create a link in a short time, but this link is more reliable and better-performing than previous communication solutions.”

“Implementing the pilot went very smoothly,” adds Dave Amps, Automation Sales Manager at Routeco, distributing both ProSoft Technology and Rockwell Automation in Britain.

“Backed-up with support from ProSoft Technology’s experts, Boulting was provided with the needed support from study, to on-field validation and to operation. At Routeco, we knew that we could rely on the high quality of the products and on the support we get from ProSoft Technology, a company we have been cooperating for more than 20 years.”

Humidity range now suitable for American influenced markets

Michell Instruments has announced the addition of a dew-point transmitter with a ¾” UNF industry standard process connection to its popular Easidew Range.
For the first time, Michell's Easidew family is available with a ‘form, fit, function’ version for industry-standard process connection – Easidew 34.

This means that the wide dew-point range and high performance of the original Easidew Transmitter is now available for the United States and American-influenced markets, such as the Middle East, Far East, Canada and South America, without the need for a process connection adapter.

Like the Easidew Transmitter, the Easidew 34’s main benefit to customers is its wide measurement range of -100 to +20°C dew point with ±2°C accuracy. This means that one sensor can be kept in stock to cover all customer ranges, which is ideal for OEMs. Applications for the Easidew Transmitter include environmentally controlled glove boxes, compressed air dryers, plastic moulding dryers, ozone generators and breathing gases.

All transmitters in the Easidew range use Michell’s advanced ceramic moisture sensor. This sensor is coupled with microprocessor-based measurement circuits to produce a calibrated unit which is fully interchangeable. Because the calibration data is stored within the transmitter, calibration service is carried out quickly and easily by replacing the sensor unit.

The transmitter is rugged enough to withstand tough industrial conditions: it has IP66 (NEMA4) environmental protection and is able to operate safely in pressures up to in 450 barg.

RFID connectivity via EtherCAT

Many users in the material handling, automobile manufacturing, and intralogistics sector see the IDENTControl concept from Pepperl+Fuchs as the answer to all their needs, because the perfect modularity and general command structure facilitate the use of RFID technology. The wide range of fieldbus solutions makes it possible for users to standardize and use a wide range of programmable logic controllers on a worldwide basis. Because LF, HF, and UHF read/write heads can be connected to the same IDENTControl interface, the system can be perfectly tailored to the relevant applications. Thus, RFID makes it easy to resolve the increasing demands for a large number of variants and short cycle times—through to just-in-time production in the automotive industry. Modularity, flexibility, and investment security are key concerns at Pepperl+Fuchs.

For example, with the new EtherCAT interface, our RFID systems can be connected directly to Beckhoff controllers. Thanks to high-speed communication, a large data range of up to 256 bytes of data per cycle can be transferred to the controller.

A parallel diagnostic interface allows the device properties and component statuses to be queried during operation. The General Station Description data can be stored as an ESI file in the controller for parameterization.

Most RFID applications require one or two readers and IDENTControl Compact is intended for this purpose. Their particular advantage, however, lies in the sophisticated EMC concept employed. However, the metal housing not only benefits EMC, but is also suitable for field mounting in IP67 in its robust version.
The flexible and modular IDENTControl from Pepperl+Fuchs
The RFIDControl Software, which is available free of charge, allows further diagnostics and parameterization functions.This means that today, it is simple to set up a dependable logistics system, an optimized goods process chain, and reliable variant manufacturing. RFID primarily distinguishes itself from barcode and 2-D code solutions through its robust read/write tags and an additionally available write function. Furthermore, RFID readers are durable, as they are based on the inductive principle and contain no moving parts.

Modular safety relays!

The Siemens Industry Automation Division now presents Sirius 3SK1, a flexible and modular range of safety relays.
The new Sirius 3SK1 safety relays from Siemens for monitoring and control systems with simple safety requirements, such as emergency stop or protective door monitoring. The product range takes the form of a clearly structured modular system so that plant operators can quickly, simply and economically assemble an appropriate and safe configuration. The Standard and Advanced basic units are available with relay or semiconductor outputs. This means that Sirius 3SK1 is able to efficiently cover every kind of application situation. The system portfolio is rounded off by modules with additional connections for actuators or sensors and a power supply.

The Standard basic units are characterised by their simple handling and variable functionality. Both mechanical and electronic sensors can be connected to the safety relay by means of screw-type or spring-loaded terminals. DIP switches on the front of the enclosure can be used for parameter assignment so there is no need for software. Should there not be enough connections for actuators on the Standard basic unit, the user can flexibly connect additional output expansions from the modular system.

The Advanced basic units feature all the product characteristics of the Standard version and not only allow the addition of modules with output expansions, but also of modules with input expansions for additional sensors. Another advantage of the Advanced basic unit: using device connectors developed by Siemens, the basic units and expansion modules can be quickly and simply plugged on without laborious manual wiring. That means there is no chance of any wiring errors occurring and commissioning is speeded up. Siemens offers a version with a rotary encoder switch for applications that require a delayed safe disconnection of actuators. There is also a Mini version of the Advanced basic unit. At just 17.5 mm wide, the Mini is ideal for use in a confined space.

The modules for Sirius 3SK1 include an inexpensive input expansion and two output expansions. The input expansion for safety applications with more than one sensor has two inputs for mechanical or electronic sensors. Depending on the application concerned, up to five of these modules can be connected to one Advanced basic unit. Siemens offers two versions of the output expansions: 4RO has four relay outputs for currents up to 4 A; 3RO has three power relay outputs for high currents up to 10 A. All of the output expansions can be combined with both the Standard and the Advanced basic unit. Furthermore, an optional power supply is also available that covers all of the world's common control voltages and supplies up to six components on the device connector – whether basic unit, input or output expansion – with 24V.
The system's modular structure helps users to cut their procurement, storage and maintenance costs. That means it is not necessary to have specific versions for specific countries, which makes ordering and warehousing so much easier.

Strategic partnership in imaging!

Mitsubishi Electric Europe has chosen Stemmer Imaging as strategic partner for the distribution of Mitsubishi Electric Europe's Contact Image Sensors (CIS) throughout Europe. Stemmer showed a first demo system with a CIS product at VISION 2012 last week.

For many years Mitsubishi Electric Europe has offered cost-effective and easy to use solutions for the development of compact optical colour readers, mainly for high end document scanning with the highest scan rates. The new KD series of contact image sensors feature a CameraLink interface, increased working distance and higher speeds and are the first sensors Mitsubushi Electric Europe have produced targeted at the machine vision industry.

Samples of the new KD series will be available before the end of this year with mass production starting in the 2nd Quarter of 2013. The colour quality in combination with the very high scan rates of this system is impressive and clearly suggests that this technology is a promising solution for demanding applications. Applications for the CIS technology can be found in all areas where flat objects and materials are to be tested quickly and with high resolution, e.g. for the inspection of printed circuit boards, printed matter or LCD panels.

The products feature scan widths of 309, 617 and 926 mm and have a colour resolution of 600 dpi and a working distance of 12 mm. The line rate of 23 kHz allows scan rates of 960 mm/s equivalent to 44 µs/line. The Contact Image Sensors supply data in both 8- or 10-bit formats over a configurable Camera Link output. The use of the integrated tri-linear sensors with filter-on-chip and white LED illumination is unusual in industrial CIS products but is proven in existing line scan cameras.

The recently signed agreement appointed STEMMER IMAGING as the distribution channel for the Mitsubishi Electric CIS KD series in all European countries starting from 1 October 2012. "Mitsubishi Electric Europe´s Contact Image Sensors complement our product portfolio in a very useful, powerful way," emphasises Peter Keppler, Machine Vision Sales Manager at STEMMER IMAGING. "With Mitsubishi Electric Europe, we now have a very reliable partner supplying this type of product for which we see a significant number of appropriate applications."

Automation in high schools in US

The Automation Federation (AF) reports that a growing number of high schools throughout the United States of America are introducing and expanding automation curricula, and exploring how the AF can assist these efforts.

Williamsport Area High School
Most recently, Williamsport Area High School in in (PA USA) requested that the AF provide technical guidance in enhancing its automation and controls course for students in grades 10-12. This news comes on the heels of an announcement in August of this year that the AF is alsop providing subject matter expertise in the teaching of new automation classes at Riverside High School in Durham (NC USA) close to AF's International Headquarters

“We recognize the importance and value to our students and our community of offering an automation and controls curriculum,” says Kevin Yokitis, department instructor at Williamsport Area High School (WAHS). “We also feel that for our automation program to reach its potential, we need to forge partnerships with industry leaders. We’re extremely excited that the Automation Federation has agreed to support us in an advisory capacity and provide subject matter expertise.”

Founded by the International Society of Automation, the AF works to advance the science and engineering of automation technologies, promote the automation profession, and develop the education and training programs that will prepare and inspire a new generation of automation professionals.

The AF is an active participant in a growing US movement - involving leaders in government, education and private industry - focused on increasing students’ interest and skills in science, technology, engineering and mathematics (STEM) within America’s educational system.

At WAHS, school administrators have been offering a course in automation and controls for the last two years in conjunction with the Pennsylvania Department of Education’s Electromechanical Technology curriculum. The school has partnered with the Pennsylvania College of Technology in Williamsport to provide dual enrollment at the college so that WAHS students taking the classes can earn college credits.

For the 2013-14 academic year, WAHS’ automation and controls course will fall within the school’s Industrial and STEM Academy, which will teach a wide range of engineering topics: safety, basic electricity, basic electronics, AC/DC motors, motor control, transformers, programmable logic controllers (PLCs), human machine interfaces (HMIs), pneumatics, hydraulics, power transmission, robotics, industry ethics, networking, engineering principles, process control and system integration.

“We’re honored that the Williamsport Area High School has asked for our assistance in building on the strong automation coursework it currently offers,” says Mike Marlowe, CNM, managing director and director of government relations at the AF. “We’ve already connected the faculties of Williamsport and Riverside high schools so they can begin collaborative discussions and share program strengths. Partnerships like this directly benefit students seeking to enhance their knowledge of technology and improve their STEM skills.”

Most educators and economists believe that stimulating interest in engineering and technology careers is essential in order to build an American workforce capable of driving needed innovation and competing in a global economy.

Marketplace demand for qualified professionals in automation and technology is increasing at a time when many of the low-tech jobs traditionally available in older industries are dwindling. A recent U.S. Department of Commerce report shows that in the past decade STEM jobs grew at three times the rate of non-STEM jobs, and that STEM workers have greater job stability.

Secure critical industrial infrastructure

New ConneXium Tofino Products Deliver a Simple Way to Secure Automation Systems

Schneider Electric has selected Tofino Security technology, from Belden Inc.,  to protect its industrial automation systems. The new ConneXium Tofino Security Solution is a suite of products that hardens industrial systems against network incidents and cyberattacks, improving operational security, reliability and performance.

In the last decade, industrial automation systems have been increasingly linked to business systems as organisations look to work smarter and more efficiently. Legacy industrial communication systems originally designed to work only within facility walls are now a hub of information activity, with intelligence passing back and forth between the plant floor and, when necessary, the outside world.
At the same time, the cyber threat level for critical infrastructure, especially threats aimed at energy, water and transportation systems, has increased dramatically.

“Processors and manufacturers are continuously threatened by new and increasingly dangerous cyberattacks, which require greater vigilance and security,” said Dave Doggett, program director for Industry Cyber Security at Schneider Electric. “The ConneXium Tofino Industrial Security Solution provides a key element in mitigating risks by managing the traffic to and from Schneider Electric automation devices before patches are applied or new more secure products deployed.”

“In addition this capability can be used to enforce plant procedure by blocking inappropriate programming commands to devices, preventing mistakes. By collaborating with the experts at Tofino Security, we are able to provide our customers with an easy-to-deploy industrial grade firewall that works seamlessly with our systems.”

The core of the new product line is the ConneXium Tofino Firewall, a rugged security appliance. By inspecting each network message that passes through it, the firewall can ensure that only the right network messages from the right computers can be sent to critical controllers. Hacking attempts, deliberately corrupted messages and even network traffic storms are stopped dead by the ConneXium Tofino Firewall.

The popular Modbus protocol is further secured using the Deep Packet Inspection capabilities provided by the ConneXium Tofino Modbus TCP Enforcer module. Only “allowed” Modbus commands from “allowed” devices go through the firewall, preventing incidents caused by inappropriate remote programming or deliberately corrupted messages from malware until appropriate patches or changes can be applied to the control system.

The firewall is configured using the new ConneXium Tofino Configurator, Windows-based software that includes Tofino’s patented Plug-n-Protect technologies. “We have worked hard to make the ConneXium Tofino a solution that can be used out of the box,” said Eric Byres, CTO and vice president of engineering at Tofino Security. “Engineers don’t need to be security experts to secure their facility with Tofino.” See Eric Byres article on the Tofino Blog, "Making SCADA Security Simple with the Schneider ConneXium Tofino Firewall" (14/11/2012).

An example of the Plug-n-Protect technologies included in the ConneXium Tofino are 15 pre-configured templates for major Schneider automation products. Engineers simply select the models of Schneider product they are using in their plant from the templates. They then decide which devices they want to allow communications to and the ConneXium Tofino Configurator automatically determines the appropriate rules. The software also includes expert technology that looks for common mistakes in firewall programming and proposes possible improvements.

Bob Lockhart, senior research analyst, Pike Research commented, “Automation systems face unique cyber security challenges that require protection, built by companies that understand how those systems work. Lacking extravagant IT budgets, automation systems also require cyber security systems that just work, with a minimum of human intervention. Companies want to focus on their core business, not the enabling technology.”

Once in the field, it is easy to keep the ConneXium Tofino Firewall up-to-date using Tofino Security Profiles. These are sets of tailored rules and protocol definitions that defend against newly disclosed vulnerabilities and malware. Each Tofino Security Profile is packaged so that it can be quickly deployed without impacting operations, thereby providing a quick and effective defense against new threats. For example, recently Schneider Electric utilized the Tofino Security Profile feature to make available mitigation against publicly announced vulnerabilities in its Modicon PLC product line, allowing customers quick access to a mitigation prior to the subsequent release of new firmware without the need to interrupt production for a firmware update until a scheduled maintenance period.

The ConneXium Tofino Security Solution is the latest offering in the ConneXium family of industrial communications and security products. Earlier in 2012 the ConneXium Eagle Firewall was released, providing boundary protection and encryption for industrial facilities.

Support for BACnet/IP

Control Technology Corp has added BACnet/IP support as a standard feature to its Model 5300 Automation Controller.

Model 5300 Automation Controller

The 5300 series programmable automation controllers can be simultaneously connected to one or more Fieldbus networks. BACnet/IP, Modbus master/slave, and CTC Binary communications are standard on the CPU module. BACnet/IP is supported on the controller’s Ethernet port. Additional Fieldbus networks are supported by Fieldbus Modules that plug into the Model 5300 backplane.

The 5300 Blue Fusion controller implements BACnet/IP so it can be either a dedicated server and/or initiate transactions as a client, monitoring online devices. As a server an external BACnet/IP client can access virtually any public variable or I/O within the controller as an object, either for monitoring or modification. In addition to supporting standard BACnet objects, the Model 5300 supports full-time synchronization and multiple read/writes.

Tom Schermerhorn, CTC’s President, was happy to announce the availability of BACnet: “We are constantly expanding our toolbox, to meet the needs of our customers. Since BACnet is designed specifically for the building automation and control industry, our customers with products or systems that manage HVAC, power, safety and security are well served by this option — an additional communications resource for specialised applications.”

Leadership in PXI

HAMEG GmbH, which manufactures T&M equipment, was bought by Rohde & Schwarz in 2005 with the aim of expanding Rohde & Schwarz’s product portfolio in the lower price segment. The HAMEG brand name was retained and the business has operated as an independent subsidiary of Rohde & Schwarz since. The distribution of HAMEG products in Britain has always been contracted to privately owned companies; this acquisition brings the products of HAMEG into the worldwide Rohde & Schwarz sales network.

Switching solutions

Pickering Interfaces is expanding its range of LXI switching solutions with the introduction of the 65-110 LXI Wideband Modular Matrix.
The 65-110 is a new modular platform providing a solution for connecting up to 16 of 104 X connections simultaneously to16 measuring devices on the Y axis with a usable BW of 500MHz. A version supporting 8 Y connections is also available for use in systems requiring fewer measuring devices.

The 65-110 is fully scalable – users can add X connections in blocks of 8 from 8 to 104 connections by simply adding or removing plugin boards to the chassis. Plugin modules can be added by users in the field; the chassis detects the presence of the plugin modules and configures the matrix as a single matrix. The modular construction is made invisible to the user to simplify programming and the Java based soft front panel presents the user with a simple integrated interface reflecting the build of the matrix via the web interface.

The matrix has been designed for high BW and low crosstalk, achieving a usable BW of up to 500MHz and crosstalk to better than 60dB at 30MHz and typically better than 45dB at 500MHz even on adjacent paths. The high performance of the matrix ensures that the 65-110 is particularly well suited to fast data acquisition systems where a limited number of measuring devices need to capture data from many potential test points, the matrix allows these signals to be connected with minimal loss and low risk of interference from other paths.

All connections are carried on SMB coaxial connectors to preserve the signal BW and ensure cabling can be adequately screened. The 65-110 includes a self-test capability that allows it to check all connection paths with the signal connections in place but not injecting current. This feature allows the matrix to be tested without having to first disconnect up to 120 RF connections. The self-test facility can be initiated through the 65-110 web pages; it requires no application program running on an external controller.

David Owen of Pickering Interfaces commented “The 65-110 has been designed to fulfil a requirement at a big physics laboratory for a matrix in a data acquisition system. We have incorporated a number of unique design approaches into the 65-110 in order to achieve the performance required. The 65-110 has been developed as an LXI platform to ensure we had the ability to design the modular sections on a footprint that was (in this case) significantly better than that which could be achieved in PXI and could include a controlled internal analog module interconnect to ensure analog signal integrity. The LXI control interface is better suited to this type of application than alternative test and measurement control methods”.

The 65-110 is fully compliant with the LXI Version 1.4 standard.

Successful wireless interoperability trial

The ISA100 Wireless Compliance Institute (WCI) has completed another successful interoperability trial in which it verified its new Generic Client Interface (GCI) specification, which is applicable to ANSI/ISA-100.11a based gateways.

Condition Monitoring & Diagnostics Software Platform
Conducted at ISA headquarters (NC USA), gateways from Yokogawa, Honeywell and Nivis successfully demonstrated interoperability with a WCI test client. The first production client to use GCI will be GE’s System 1® product which was also successfully tested during the trial.

System 1® is GE’s patented conditioning monitoring software platform for real-time optimization of equipment and selected processes, condition monitoring and event diagnostics that enables plant personnel to quickly identify important events, evaluate the situation and respond, leading to increased equipment availability, reliability and reduced maintenance costs.

ANSI/ISA-100.11a is flexibly designed to support legacy and/or proprietary protocols and the GCI is an example of how the ANSI/ISA-100.11a wireless standard can deliver that result.

“We are excited to see the success of this interoperability test conducted by the ISA100 Wireless Compliance Institute. WCI plays a crucial role in the success of ISA100 in the industrial space," said Hitoshi Yasui, general manager of Wireless Research and Development Business Unit, Yokogawa Electric Corporation. "Yokogawa has demonstrated leadership in defining, developing and deploying the ISA100 family of standards. We believe unique features of ISA100 allow Yokogawa to provide solutions to meet our industrial customers’ requirements. Customer satisfaction has always been, and will always be, the primary goal of Yokogawa."

“With the successful outcome of the test, we continue to look forward to additional interoperability tests planned for the coming year with more ISA100-certified products in the queue to confirm the scalability, reliability and performance benefits of the ANSI/ISA-100.11a standard,” said Andre Ristaino, managing director of WCI.

GE Intelligent Platforms today announced the bCOM6-P1100 Rugged Type 6 COM Express Module, a board designed for deployment in challenging or harsh commercial environments such as mining, forestry, construction, oil & gas, food & beverage, networking, industrial automation control and power & energy. The company has incorporated its extensive experience in developing high performance rugged solutions for military applications into this new product.

The bCOM6-P1100, which expands GE’s COM Express portfolio by adding a Freescale™ PowerPC™ processor, also takes advantage of GE’s expertise in the optimization of thermal performance.

“Any manufacturing company producing fewer than 10,000 units per year should be seriously considering COM Express,” said Tommy Swigart, Product Manager, GE Intelligent Platforms. “The COM Express architecture is uniquely attractive for many applications because of its price/performance, extremely low power consumption, modularity, flexibility, longevity and investment protection, and the bCOM6-P1100 implementation brings those benefits to customers who also need a solution that can withstand deployment in hostile environments.”

“For organisations looking to take advantage of the benefits of COM Express technology in locations beyond the data center or office environment, the bCOM6-P1100 offers the optimum solution.”

GE specifically selected on-board components for their reliability in demanding conditions, and, unlike solutions designed for benign environments, processor and memory are soldered to the board for maximum resistance to shock and vibration. Extended mechanical construction protects the module, which is designed for optional conformal coating for even greater resistance to moisture, dust, chemicals, and temperature extremes.

The small form factor of the COM Express architecture is attractive to organizations looking to deploy embedded computing in constrained environments, while its separation of processor and carrier board allows simple, cost-effective upgrades that enable optimum operation to be maintained, minimize re-qualification costs, maximize asset performance and decrease lifetime cost of ownership.

For OEMs and systems integrators looking for solutions that deliver high performance coupled with low power consumption, the bCOM6-P1100 offers a range of two Freescale PowerPC QorIQ processor options, with performance between 800MHz and 1.2GHz (x2) and power consumption between 3.5W and 13.0W. Up to 8GB of DDR3 SDRAM with ECC can be configured, allowing the most demanding applications to be deployed.

Plant monitoring

Upgraded condition monitoring software for preventive maintenance

The effective maintenance of plant and machinery depend heavily on the quality and quantity of data acquisition and analysis. In version 03.05 of its monitoring software Siplus CMS X-Tools, the Siemens Industry Automation Division has provided a range of new maintenance functions.

For any modern manufacturing company, high plant availability is crucial. This makes it all the more important to ensure that efficient maintenance methods are in place. Siemens addresses this problem with its condition monitoring system Siplus CMS and monitoring software X-Tools for add-on integration into existing automation systems. They come with an extensive library of functions for analysis, diagnosis and condition monitoring. The upgraded version of Siplus CMS X-Tools V03.05 provides an array of new functions to simplify and improve scope for condition monitoring. The Fast Analysis function allows archived and real time data to now be evaluated even more quickly and simply. Using the extended report functions, users can now generate their own event-driven trend graphs. New vector diagrams permit improved evaluation, for example of network situations.

Additional measurement cursors – now numbering up to 99 – also provide greater scope for measuring data and evaluation: The cursors are updated and automatically displayed on a speeddependent basis. Damage-typical frequency markers allow users to quickly and easily identify progressive damage. Using a new process-controlled trigger marking system, archived measurement data can be simply located and assigned as required.
The main illustration (left) shows a raw signal and a velocity signal (red line).The two illustrations on the right show two different damage analyses: at the top next to a main cursor five sideband cursors (orange lines) and below seven harmonic cursors (green line)

PM monitoring

A new report published in September 2012 by the European Environment Agency shows that almost a third of Europe's city dwellers are exposed to excessive concentrations of airborne particulate matter (PM); one of the most important pollutants in terms of harm to human health because it penetrates sensitive parts of the respiratory system.

Colin Craggs from instrumentation specialist Air Monitors says “This is a timely reminder of the dangers posed by particulates and coincides with the UK launch of a fixed area dust/aerosol monitor for continuous monitoring and a portable monitor for personal exposure at multiple locations.”

Both instruments are manufactured by Thermo Scientific and Colin says “National ambient monitoring systems are already in place and strict regulations restrict the PM emissions from industry and vehicles. However, employers have a duty of care to protect their staff, so accurate monitoring of the workplace is essential.”
PDR 1500

The new PM monitors are the latest versions of well-established and proven techniques offering a complete solution for monitoring particulate exposure in industrial and occupational safety applications including COSHH/NIOSH assessments.

Both the ADR-1500 Area Dust Monitor and the pDR-1500 Personal Aerosol Monitor employ light scattering photometers (nephelometers) with relative humidity compensation and true volumetric flow control to provide high-precision, real-time results with optional gravimetric validation.

In order to be able to function in a wide variety of applications, these high resolution instruments offer an extremely wide measurement range - 0.001 to 400 mg/m3 (auto-ranging) which covers all particulates from PM-1 to PM-10.

Weighing just 13kg, the ADR-1500 Area Dust Monitor has a weather-proof IP65 housing and a handle which allows for ease of transport and installation with mounting options available for wall, post or tripod locations. With a choice of AC or DC power, the ADR-1500 is simple to set up and run. Data are recorded at intervals ranging from 1 second to 1 hour, and the unit will issue an alarm as soon as PM levels reach a dangerous (user defined) level.

Weighing just 1.2kg, the pDR-1500 personal monitor can run from a fixed position or worn on a belt to facilitate real-time measurements as the user moves from one location to another. This personal monitor offers the same data recording capability as the area monitor and features interchangeable cyclones for superior particle cut points for PM10 & PM4 or PM2.5 & PM.

Summarising Colin Craggs says: “The pDR-1500 enables occupational safety managers and consultants to conduct accurate surveys in order to assess the levels of risk and identify potentially dangerous areas. The ADR-1500 complements this product by providing the ability to continuously monitor those areas and ensure the protection of staff and visitors.”

Flexible Wireless

More flexibility for network setup with wireless data transmission

The Siemens Industry Automation Division has equipped its Scalance W modules for Industrial Ethernet networks with a range of new functions for certain types of outdoor application. The new Scalance W786-2 SFP (Small Form-Factor Pluggable) units now offer an additional integrated switch with two slots for pluggable SFP transceivers.

Wireless networks – Industrial WLAN – have become an established solution across a wide range of industrial applications. However, providing reliable network coverage over long distances, particularly outdoors and in environments more difficult to cover with IWLAN, has posed something of a challenge to date. Adequately solving this problem calls for a combined solution with fiber optic cabling. The Siemens Industry Automation Division has now come up with an addition to its line of outdoor access points which addresses this specific issue. The new Scalance W786-2 SFP comes equipped with an additional integrated switch featuring two slots for pluggable SFP transceivers. These can optionally be equipped with transceivers for single or multimode fibers to provide gigabyte Ethernet bandwith. Several of the new Siemens access points can be used in a lined structure in this way there is no need for additional hardware. The new feature allows larger areas to be covered by IWLAN for outdoor applications, ensuring the reliable transmission of both process- critical data and non-critical communication over a single wireless network.

The Scalance W786-2 SFP access points are available in both a standalone and a controller-based version. Both come with two integrated wireless interfaces in compliance with Standard IEEE 802.11abgn, each with a gross transmission capacity of up to 450 Mbit/s. As a result, the new units are ideal for the creation of industrial wireless LAN (IWLAN) networks with a 2.4 GHz or 5 GHz transmission range suitable for providing coverage in even remote or inaccessible terrain, and in aggressive environments. The internal R-SMA connectors allow the connection of up to three antennae per wireless interface. Both variants come with an IP65 protection rating, cased in impact-proof plastic housings suitable for use at temperatures between -40°C and +60°C.

Although fitted with a direct 24V DC terminal, the units can also be operated at 110V AC or 230V AC with an optionally integrated PS791-2AC power supply adapter. Equipped with a C-PLUG interchangeable storage medium allows existing configurations to be stored, permitting fast exchange of devices in the event of a failure.

Base/Plinth system

Rittal’s new Flex-Block base/plinth system is now available from stock to suit Rittal floor standing enclosures ,TS 8, SE 8 and CM along with floor standing human interface products TP and PC.

The Flex-Block plinth is made up of four fibreglass reinforced corner pieces that fix directly to each corner of the enclosure, either to the frame or the base tray. These blocks support the whole weight of the enclosure providing direct access to the whole of the underside allowing for cable management or pallet trucks for simple transportation. With provisions for threaded inserts, the corner pieces allow for castors or adjustable levelling feet to be installed with the minimum of effort without tools.

With all the corner pieces in place it is possible to clip fit, or mechanically fix, accessories such as punched section for the use of Rittal standard accessories such as cable management, punched section, cable restraints, etc., providing a solid easy solution for cable access when working at low level.

All plinths are supplied with trim panels made from sheet steel and painted in RAL 9005. These can be clip fitted without the use of tools or fixings, which have been tested to withstand the rigours of transport and vibrati-ons. For additional security there is also the option to screw fix the trims along with points for earthing the trims.

With the TS 8 bayable range of enclosures in mind it is also possible to bay the plinths together complementing the install. This is also very simple and easy using the baying clip supplied as an accessory.

Weighing module

A versatile weighing module for the Simatic S7-1200 is being launched by Siemens.

Siwarex WP231 is the first weighing module for this control and is suitable for monitoring filling levels in silos and bins and for use with goods being weighed on platform scales. The new model is intended for industries requiring a high level of measurement accuracy, such as the food and beverage, pharmaceutical and chemical industries. Furthermore it is suitable for use in explosive atmospheres. Ethernet connections and an RS485 RTU interface with Modbus protocol enable it to be operated from a Modbus HMI panel without being connected to the Simatic S7-1200 control.

Siemens' new Siwarex WP231 weighing module can be fully integrated into the Simatic S7-1200 control, and its parameters can be quickly and easily set via the TIA Portal engineering platform. The module has four digital inputs and outputs and one analog output. The Siwarex WP231 can be connected to various systems and operator panels via an Ethernet or RS485 interface with Modbus protocol and can be operated independently from the Simatic S7-1200 ("stand-alone capability"). This makes it possible for the module to be used in various applications. In addition, the module can be operated directly from a Modbus HMI panel in the event of failure of the control unit.

Whether operating in stand-alone mode or in combination with the Simatic S7-1200, the Siwarex WP231 offers a wide range of settings for parameters and alarm management, thus enhancing process efficiency. Users can define specific limit values and different parameters for the various individual outputs. Additional diagnostic functions, such as the documenting of weight and various process parameter readings (Trace), make for greater transparency and facilitate the commissioning and maintenance of the module.

Due to its high resolution – one million parts – and a measurement cycle of 10 milliseconds, the Siwarex WP231 is able to measure with a high degree of accuracy. Clear menus mean that the weighing module is easy to operate, whether in conjunction with the Simatic S7-1200 or via a directly connected HMI panel. Moreover, thanks to its automatic set-up function, the measuring system is ready to use within only a few minutes.

Ultrasonic interface sensor

The Turbimax CUS71D ultrasonic immersion sensor for interface measurements in processes where suspensions are separated into their liquid and solid components by sedimentation has been introduced by Endress + Hauser. It can monitor the separation and transition zones of the clarification and settling phases continuously.

The sensor uses a piezoelectric crystal to generate an ultrasonic signal, and measures the time required for the signal to reach solid particles in the separation zone, and then return to the receiver. The sensor is used with their Liquiline M CM44x series of transmitters to form a complete measurement system.

The speed of sound varies according to the physical properties of the measuring medium and is affected by temperature and air pressure. The composition of the liquids and solids can also vary. Endress+Hauser’s M CM44x multi-parameter/multiple sensor transmitters are able to compensate and adjust for these changing process conditions, ensuring accurate measurement.

The transmitters can mask out regions where the separation zone is not expected, evaluate received signal strengths, select leading or trailing signal edges in the evaluation, and define a region above and below the expected separation zone to serve as a “gate”—that is, signal evaluation takes place only in the defined region. The gate can “wander” with the separation zone as required for accurate measurement. The CM44x can also amplify sensor signals at different rates to account for process conditions such as floating sludge.

One sensor can be connected to a CM442 transmitter, and up to four sensors can be connected to a CM444 or CM448 transmitter. Multiple sensors may be needed for monitoring more than one tank, for monitoring more than one interface level in the same tank, or for other applications.

The CM44x transmitter can include up to eight 4-20mA current outputs, eight relay outputs and two analog inputs. The transmitter can be configured as Ethernet-based webserver, and this integrated webserver option provides remote access via any web browser. Hart, Profibus, Modbus TCP and Modbus 485 digital busses are also available as an alternative to analog outputs.

The transmitter has a back-lit graphic display with drop-down menus for monitoring values, and displays outputs from the built-in data logger. The data logger can maintain up to eight separate data logbooks, with 150,000 entries per logbook. The data logger has an adjustable scan time of one second to six hours, and a logbook that keeps track of up to 75 calibrations.

Two sensor models are available: a standard sensor and a sensor with a wiper to avoid film and air bubble formation at the sensor transducer. Each model can detect the interface level at distances of 1-32 ft from the sensor with a maximum error of 1.3 inches (35 mm).

The sensor can be installed in open basins, channels and tanks. It operates in process temperatures from 34 to 122 ºF, and pressures up to 87 psi. Mounting hardware is available in stainless steel or PVC.

Applications for the CUS71D/CM44x measurement system include:
  • Wastewater treatment: primary clarifier, sludge thickener and secondary clarifier
  • Drinking water: settling basin after flocculant dosage, filter media expansion monitoring to optimize backwash operations, monitoring sludge height
  • Chemical industry: static separation processes
Endress+Hauser manufactures equipment at its Conducta production facilities in the USA and in Germany, both ISO accredited facilities. Calibration of the sensor is accomplished by the factory, with all calibration data residing in the sensor, making field calibration unnecessary and ensuring optimum performance.
