This article will explore the use of a wireless diagnostic OLE for Process Control (OPC) server technology to embed diagnostic information in human machine interfaces (HMIs), thus optimizing industrial wireless network performance.11/01/2007
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.11/05/2007
This whitepaper is the first in a series on the security of OPC (OLE for Process Control) and focuses on providing an overview of the widely-used industrial communication standard and how it is actually used in industry.04/13/2007
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.04/04/2007
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.12/03/2007
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.01/16/2007
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.09/13/2007
The Mu-4000 Security Analyzer has emerged to help QA integrate optimized negative testing without impacting productivity. It delivers metrics related to service availability and security, resulting in the vendor knowing it is shipping higher quality products.08/13/2007
The objective of this white paper is to educate the reader on the selection of point level monitoring technologies for specific applications to improve process efficiency, reduce up-front costs and minimize overall cost of ownership.08/14/2007
Manufacturers of level measurement technologies are often asked to recommend a technology for measuring bulk solids in vessels. Understanding the technologies available is an advantage when searching for an answer to the question of what to do.08/14/2007
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.05/18/2007
The first and only question a customer has in mind when selecting a GCMS is: How sensitive is it?11/08/2007
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.03/19/2007
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.05/30/2007
This paper presents the results of tests conducted on ways of reducing the four types of noise encountered in electronic instrument circuits.
The use of computers and other sensitive electronic equipment in process instrumentation systems has demanded that more attention be give to electrical noise pickup in instrument circuits.
The superior performance of aluminum-Mylar tape shields in comparison with copper braid and copper served wire shields for static noise rejection is described.
The effect of twisting wires to cancel magnetic noise is compared to various shielding materials. Twisting the wires is shown to be the most effective practical way of reducing magnetic noise.
The control of common mode noise by the proper grounding of shields in thermocouple circuits is shown. The use of single grounding points in shield circuits grounded at the couple is recommended. Multipair cables with individual isolated pair shields are recommended.
Comparative results on cross talk elimination in multipair cables are presented. Individually shielded pairs are recommended as the most practical means of cross talk rejection in instrument circuits.12/12/2007
