This white paper supports the case for the use of a thermal anchor for temperature uniformity over a range of temperatures, which can dramatically reduce design and development time while actually improving thermal performance in the process.
The benefits of Advanced Process Control (APC) technology are deemed so significant that many manufacturing experts consider the use of APC a necessary requirement to remain competitive. A closer look into the technology may reveal the reason.
There is a significant difference when it comes to birds and control systems from a perspective of migration. While some of the birds migrate back to its original place after the seasonal change, the reasons of migration does not change! This paper describes a successful approach towards migration of legacy control systems and draws analogy from the above for the purpose of illustration.
This report presents evidence in support of a business case for improving security of Supervisory Control and Data Acquisition (SCADA), process control networks (PCN), and manufacturing and industrial automation systems based on an analysis of statistical trends in security incidents.
This paper provides a current snapshot of the IT/controls dynamic based on interviews with more than 20 professionals in IT and manufacturing. Their feedback was the foundation for development of a maturity model that shows the three distinct paths and five stages of maturity for each of the major categories of issues: organizational, business process, technology deployment and results.
This papers talks about the cost of safety programs and systems that United States businesses have to pay. Learn about what would happen if your employees suffer accidents and there are inadequate safety measures in place? What if nothing happens?
This white paper explores fuzzy logic and how it helps engineers solve nonlinear control problems commonly found in process applications. Fuzzy logic, which mathematically emulates human reasoning, provides an intuitive way to design function blocks for intelligent control systems, advanced fault detection and other complex applications. Control systems deploying fuzzy logic can improve the management of uncertain variables, such as temperature fluctuations.
This white paper approaches the process of alarm management from the unique perspective of a dynamic optimization problem. Process pitfalls and solutions are discussed, and suggestions are offered on how to formulate an approach to analysis and solution development that is not limited by static preconceptions and artificial restrictions.
This paper shows how combining safety and non-safety functions in a safety instrumented system (SIS) is acceptable, and indeed practiced, in many facilities worldwide, and suggests eight implementation and testing precautions to follow so that a safe and reliable application can be anticipated.
A lot of papers, articles, and guides have been written over the recent years addressing Continuous Process Improvement (CPI). However very few address methodologies related to the improvement of the process itself, that is, the processing of the metrics used to measure the effectiveness of a process. The methodology proposed in this paper can be applied to any processes.
Since 1994, PAS has benchmarked hundreds of alarm systems in various industrial markets around the world. From our project databases, this paper presents examples of the worst, most overloaded alarm systems encountered. In addition, the possible solutions to these problems are discussed.
As the technological differences between PC and PLC wane, a new class of controllers is emerging for engineers who require higher loop rates, advanced control algorithms, more analog capabilities, and better integration with the enterprise network. The Programmable Automation Controller (PAC) describes this new generation of industrial controllers that combines the functionality of a PLC and a PC.
Nearly every product, service, application and data type is moving to an IP-based infrastructure. As a result, formerly isolated products in homogenous networks are embedded within heterogeneous deployments, resulting in dramatically larger and more complex attack surfaces that are exposed to a wide variety of potential attack sources.
This whitepaper, written by Vince Marchant, a senior application engineer at Moore Industries, describes how Modbus works, and how it can be used in new and legacy process control and automation systems.
