Balluff experts explain the three fundamental qualities that determine if RFID systems will perform reliably in demanding production environments. It answers three main questions: Will the RFID system integrate seamlessly with industrial control systems? Will it provide the reliability and speed that production and information systems require? Can it maintain uptime and performance long-term?03/11/2014
The Surge-Trap is a branded surge protection device (SPD)that utilizes Mersen's patented thermally protected metal oxide varistor (TPMOV) technology. This technology eliminates the need for fuses to be installed in series with the Surge-Trap SPD.
which saves money and panel space. Surge-Trap SPD is typically installed in industrial control panels to protect sensitive electrical equipment from harmful voltage transients. Nearly 80% of all transients are caused by equipment or power disturbances within a facility.
What Types of Ratings Do SPDs Have?
Do SPDs have a current rating? This is a trick question! They do not have a continuous current rating however they do have other important current-based ratings. They are required to have a short circuit current rating (SCCR), which is the maximum rms current at a specified voltage the SPD can withstand.
The nominal discharge current (In) is new to UL 1449 Third Edition (effective 9/29/09). This is the peak value of the current (20kA maximum) through the SPD (8/20μs waveform) where the SPD remains functional after 15 surges.
There are two main voltage ratings for an SPD, the first is maximum continuous operating voltage (MCOV) which is the maximum rms voltage that may be applied to the SPD per each connected mode.
Voltage protection rating (VPR) is determined as the nearest high value (from a list of preferred values) to the measured limiting voltage determined during the transient-voltage surge suppression test using the combination wave generator at a setting of 6kV, 3kA.

For decades, process instrumentation specifiers have faced the decision whether to use a mechanical switch or a continuous transmitter for a given application. Either type of instrument can be used to effectively control industrial processes and protect equipment and personnel -- and each has associated pros and cons. Application specifics typically drive decision-making, dictating which approach is most effective from performance, cost and lifecycle support perspectives.05/16/2013

This paper provides background on, and an overview of, the soon to be released WBF XML batch and enterprise-control system schemas. The schemas consist of two sets, one is intended to provide for the exchange of batch data and is based upon the ANSI/ISA 88 standard. The second is intended to serve as a basis for exchanging data between enterprise and control systems and is based upon the ANSI/ISA 95 standard. The organization of each set is described along with examples on how they can be used.08/25/2008

A Comprehensive Plant Crew Training Solution Improving Process Reliability and Safety
One of the key challenges that capitalintensive industries will face over the next five years is replacing the gray-haired workforce with the computer-savvy/gaming generation. High-fidelity operator trainer simulators that represent the production process, control system and the control room interface have proved to be very effective for control room operations training. However, for the remaining 50% of the plant start-up procedures that are executed in the field, no fully interactive training environment has been available - until now.
Industries like oil and gas, refining and power companies need to institutionalize their workforce knowledge in more efficient and effective ways. Leveraging Virtual Reality (VR) models to improve time-to competency in critical areas like safety, environment protection systems, knowledge, performance training, and reliability provides a vehicle to rapidly train the new workforce in ways that align with their interests and skills.
With continuing advances in hardware and software techniques Virtual Reality (VR) is accessible today as the best aid to multimedia training, process design, maintenance, safety, etc. which are currently based around conventional 2-Dimensional (2-D) equipment views.
The real time rendering of equipment views puts demands on processor time and so the use of high fidelity simulators is becoming more and more of a standard in process understanding and training. Within many VR commercial projects in the past, the results have either been unrealistically slow or oversimplified to the detriment of the solution effectiveness. As the technology continues to develop, these issues have been eliminated, giving way to a new process simulation era that is based on commercially standard IT hardware.
IVRP (Immersive Virtual Reality Plant) now provides a large range of effective multimedia aids that are easily and economically accessible to support design, training, maintenance or safety in the process industry by linking the power of dynamic simulation - DYNSYM - to VR applications and tools.

On September 11, 2001, America was attacked by terrorists and the United States quickly acknowledged vulnerabilities at our airports, borders, food supply and water supply systems. Soon after, the government required vulnerability assessments (VAs) for all municipalities with large cities required to go first. In 2002, Madison Water Utility (MWU) in Madison, Wisconsin, underwent its VA and saw a need for video cameras at many locations, including 32 remote sites.
Two obstacles stood in the way of Madison meeting this need:
- Technology--whose cameras, network and communication system? How can video work with our SCADA system?
- Money-- who will pay to protect Madisons water supply?02/24/2009
With the economy slowing down on a global basis, managers are reluctant to spend money or move forward on prior plans. Indeed, many companies are postponing or cancelling projects and many have begun cost cutting measures that almost always mean job eliminations.Reducing costs is a responsible management action; the goal is to protect the return on the investors equity. Video can provide a solution to many of the issues that remain, even when people are laid off or factories are closed.03/12/2009
Using video data to improve both safety and ROI.
Most companies are gathering trillions of bytes of data, day after day, at no small cost, and then doing very little with it. Worse still, the data often is not serving its primary function very cost-effectively.
The "culprit," so to speak, is video surveillance data, the information captured by the video cameras that are used throughout most modern facilities.
But the situation is changing rapidly, thanks to an application called Video Analytics. This white paper looks at the new software technology, and how it can be used to leverage video data for better security and business performance.03/05/2010

The eXtensible Markup Language (XML) was released by the World Wide Web Consortium (W3C) in 1998 and has experienced rapid worldwide acceptance. When the SP88 committee started work on the S88.02 exchange tables XML technology was not available for consideration and relational database table technology was used as a basis for batch data exchange. As applications come to market based on S88.02 it is important to examine the newer XML technology for suitability for batch data exchange. This paper provides a brief overview of XML and discusses how it can be used for batch data exchange. As an example an application that converts a control system's proprietary master recipes to and from XML is discussed. Lessons learned about the use of XML versus relational database technology are presented as well as possibilities for future uses of XML with batch control.08/26/2008
