As the next generation of distributed control systems (DCS) becomes firmly established in the marketplace, each manufacturer must face the issue of upgrading. DCS vendors already have plans to phase out support of many current platforms, so it's critical that you develop your own plan for moving forward. The most proactive plants already have a plan in place, while others might continue scavenging for spare parts to keep their existing controllers alive for as long as possible. Of course, every control system has a limited lifespan and must be upgraded eventually. The big question is when. Download this white paper to learn when you should upgrade your DCS.06/04/2012

Strategic philosophies or practices such as Kaizen, Lean Manufacturing, Six Sigma, Total Quality Management and Continuous Improvement are used by many organizations to help improve processes, drive productivity and maintain a competitive edge in today's ever-increasing global economy. Despite varying concepts, each practice uses key performance indicators (KPIs) to assess, analyze and track business manufacturing processes. Even if an organization does not employ formal continuous improvement initiatives, efficiency gains can still be realized by borrowing lessons learned through the visual management techniques of those processes. This white paper discusses three common visual management solutions for displaying KPIs and andon messages in order to drive productivity and improve profitability.05/21/2012
This paper provides an overview of key global trends and regulations relating to packaging, electrical and electronic equipment and batteries. It lays out the challenges of compliance and consequences of non-compliance, and warns that the approach many companies are taking today will not scale with the rapid growth and increased complexity of regulations and industry or supply chain requirements. Finally, the paper addresses the benefits of best-in-class approaches to environmental management programs and the systems needed to support them.05/21/2012
This toolkit comes with everything you need to eliminate the environmental effects on wiring, such as temperature cycling, vibration and corrosion, as well as in cabinet challenges related to space restrictions, circuit identification, power distribution and more.05/21/2012
ABB's Flow Measurement Handbook has helped generations of instrumentation practitioners navigate the application ins and outs of industrial flow measurement devices. Its latest edition, entitled Industrial Flow Measurement -- Basics and Practice, is available here in manageable chapters, downloadable as PDFs, beginning with "Introduction to Flowmeter Physics Essentials," including fluid mechanical concepts such as viscosity, Reynolds number, turbulence, energy and flow rate equations.05/14/2012
The widespread use of digital instrumentation with a digital communications protocol calls for new thinking about the traditional tools used by technicians for instrument maintenance and calibration. HART protocol instrumentation is by far the most used of this type of system. The HART Maintenance Device would be just such a tool, providing basic communications and diagnostic capabilities to support the maintenance and troubleshooting of HART instruments.05/14/2012
Operational Risk Management: A Clear Path to Proactively Managing Risk and Ensuring Operational Continuity
Without a consistent way to manage people, assets and process safety, companies are more susceptible to risks that drive up costs and can cause serious incidents. You must proactively manage and reduce operational risk, but it requires discipline. This SAP Executive Insight Paper answers the following questions:
- What can we do to ensure operational continuity?
- How can we give our people the skills and tools necessary to ensure safe operations?
- How can we manage operational risks while delivering return on investment?05/14/2012
The third edition of this handbook has been totally revised to include new chapters on Electrical Measurements, Vibration and Sound, Displacement and Position Sensing, and Transducer Electronic Data Sheets (TEDS). It also includes several new subjects and expands on selected items including Fundamental Signal Conditioning.
All chapters have been enhanced to address more practical applications than theoretical measurement issues. They cover a major topic with sufficient detail to help readers understand the basic principles of sensor operation and the need for careful system interconnections. The handbook also discusses key issues concerning the data acquisition system's multiplexing and signal conditioning circuits, and analog-to-digital converters. These three functions establish the overall accuracy, resolution, speed, and sensitivity of data acquisition systems and determine how well the systems perform.
Data acquisition systems measure, store, display, and analyze information collected from a variety of devices. Most measurements require a transducer or a sensor, a device that converts a measurable physical quantity into an electrical signal. Examples include temperature, strain, acceleration, pressure, vibration, and sound. Yet others are humidity, flow, level, velocity, charge, pH, and chemical composition.04/23/2012
The last 10 years have seen a major expansion of the use of wireless data technology in every aspect of life and in every industrial venue. From the ubiquitous cell phone to smart phones, tablets and more, wireless data communications have become an important, perhaps the most important, medium. In the last half dozen years, wireless field devices have begun penetrating the industrial environment too. IT and plant floor communications managers are faced with a daunting task in coordinating all the uses of wireless in the average 21st-century plant.
As more and more wireless devices and applications become an integral part of the industrial arena landscape, concern grows over in which layer of the network these wireless devices should be placed. This question concerns everyone since this is sure to impact plant or plant operation in the near future.
We typically see two physical networks. The Process Control Network (PCN) involves Layers 2 and below. The Business Network (BN) involves Layer 4 of the Purdue model. If you are part of a plant team that supports either of these networks, the discussions within this paper have been or will be part of an ongoing discussion for your organization.
We've seen a number of major companies make an attempt to stake out where wireless devices will fall and under what level of the network. This paper addresses these types of issues and is intended to provide answers to the many questions that are sure to arise.04/23/2012
New automation technology advances and investments in industrial control systems for equipment, machinery and infrastructure led first to distributed I/O, and now, to enclosure-less I/O. While quick disconnect connectors and enclosure-less I/O systems have been available for years, new industrial designs often still use enclosure-based strategies for I/O. These older, centralized enclosures come at a high price. This paper explores the impacts connectivity and cabling have had on streamlining equipment, and the tradeoffs between enclosure-based systems and enclosure-less based I/O systems.04/23/2012

For the past decade, industrial control systems administrators and engineers wanted to believe that 'air gaps' truly existed between their systems and the rest of the world. They have also hoped that 'security by obscurity' would keep them safe from security threats. Those days are over. While the consequences of cyber attacks and malware are no longer in doubt, the question remains. "Exactly how can an engineer reliably secure his or her control system?" This white paper outlines a simple and cost effective answer - a security solution based on OPC technology that can be deployed in almost any industrial facility today.04/09/2012
