Although the stability of off-the-shelf computer hardware and operating systems has improved significantly over the last few years, system failures can and still do occur. A proper redundant OPC architecture can prevent these component failures from leading to loss of control or a disruption of electrical service. In order to ensure the constant operation of their OPC applications, industry leaders turn to OPC vendors and products such as MatrikonOPC that provide mission-critical redundancy.08/06/2012
An unfortunate stumble during DCS migration could trip up your career, but a clear path forward will deliver benefits for decades to come.

Process measurements are instantaneous but analyzer responses never are. From the tap to the analyzer, there is always a time delay. Unfortunately, this delay is often underestimated or misunderstood.
Time delay is defined as the amount of time it takes for a new sample to reach the analyzer. One way to control time delay is with a regulator. Regulators control pressure, and pressure in an analytical system is closely related to time. In the case of gas systems with a controlled flow rate, the lower the pressure, the shorter the time delay.
Delay may occur in any of the major parts of an analytical instrumentation (AI) system, including the process line, tap and probe, field station, transport line, sample conditioning system, stream switching system, and analyzer.08/03/2012
OPC is the current de facto open communication standard in the world of industrial connectivity. It offers improved data connectivity, while lowering the cost of data transfer between devices and applications. The most widely used OPC specifications employ communications layered on top of various Microsoft operating system components. These components function very well under office-like LAN conditions, but under less favorable conditions, their behavior often leads to unreliable data delivery, and even data loss. Download this white paper to learn how OPC Tunnelling technology provides a solution to this problem.07/30/2012
Communicating To the Enterprise Isn't Science Fiction. Wouldn't it be nice to be able to transport any object across great distances almost instantly? In the building automation systems of today's buildings and facilities, real-time information does just that. A modern building management system monitors and operates all technical facilities. Managing these data sources ensures optimal building performance by enabling control of building systems in an integrated manner. However enterprise facility management requires more than just building automation control systems. Download this white paper to learn how you can improve the design and operation of building processes, reducing emissions and improving energy usage, by connecting building automation systems to the enterprise using OPC.07/25/2012
The first step in migrating to a new automation system is often financial justification. Learn to accurately analyze the total cost of ownership for continued operation on an outdated DCS and how to justify the benefits of replacing it with a new system.07/25/2012
Every year businesses and individuals lose more than $4 billion in damaged equipment to lightning strikes, transmission line surges, ground loops and other electrical events. Downtime and lost data add additional costs. Most of this trouble can be avoided through the use of isolation devices.07/17/2012

Flameproof enclosure (Ex d) and intrinsic safety (Ex i) are very common equipment protection methods in Process Automation. One reason to use Ex d is the amount of energy which could not be provided via Ex i. This disadvantage has gone with the introduction of intrinsically safe, dynamic methods of arc prevention such as DART or Power-i. This white paper shows that when using intrinsic safety, installation, maintenance and inspection costs will be reduced.
This paper addresses decision makers and professionals responsible for automation systems in hazardous areas. A good understanding of the principles of explosion protection is required.07/10/2012
Clearly the need - and potential payoff - for more effective operators is enormous and intuitively understood. But rather than reversing course and simplifying operators' tasks, industry is only increasing the pressure. Learn how to transform your people into strategic assets.07/10/2012
Pundits have been predicting the death of manufacturing in North America and western Europe for decades. It hasn't happened yet, and it probably won't happen at all. The markets and the manufacturing capacity are so large it seems certain that manufacturing in North America and western Europe will continue.
While it may be true that manufacturing in the First World is becoming more competitive, this isn't a passive phenomenon. Companies that offer innovative product development, manufacturing operations and business practices are more able to respond to changes in business conditions on a global basis than companies that believe they are world-class and thus don't have to change.
To stay competitive in the global market, all your systems must be integrated to produce the least possible friction as materials become products and move to distribution. Friction occurs when systems don't talk to one another easily or simply don't interface well at all - and it costs money. It's time to take a fresh look at your manufacturing operations, from supply chain to distribution channels, and make sure they are all integrated, both horizontally with each other as well as vertically to the business systems of the enterprise. And during that fresh look, you need to look at your existing manufacturing assets.
In the First World, it is simply not possible to knock down existing plants and build new ones from a green field. When you develop your strategic agility plan, a big part of it is going to be making all your existing assets work together in an integrated fashion.

When you have hundreds of different data acquisition (DAQ) devices to choose from on a wide variety of buses, it can be difficult to select the right bus for your application needs. Each bus has different advantages and is optimized for throughput, latency, portability or distance from a host. This white paper examines the most common PC bus options and outlines the technical considerations to keep in mind when choosing the right bus for your measurement application.07/09/2012
Need to upgrade your DCS soon? You're not alone. A recent study shows that 68% of control engineers plan to upgrade within the next six months.
