Maintaining a competitive edge is becoming more difficult as energy costs continue to rise. By investing in sustainable buildings, manufacturers are improving bottom-line business performance and creating value through integrated financial, environmental and social strategies and measurements.
Dow Chemical maintains thousands of batch control systems world-wide built on its proprietary MOD 5 computer system. Over decades, they have been meticulous to preserve and enhance these systems. Dow intends to preserve and reap the rewards of this diligence by developing reverse engineering best practices and tools to migrate this intellectual property to next-generation platforms.
Batch manufacturing systems must maintain the status of equipment, including which are available, dirty, out of service, etc. In industries that enforce Good Manufacturing Practices (GMPs), additional status types and values for process equipment must be maintained. Rules associated with the equipment status can be complex and involve the equipment class, current equipment state and time in the current
state. This paper covers the operator interface used to review the equipment status and the interlocking requirements between the recipe and batch phases based on multiple status types.
The power industry is susceptible to a variety
of cyber threats, which can wreak havoc on control systems. Management, engineering and IT must commit to a comprehensive approach that encompasses threat prevention,
detection and elimination.
This document describes best practices for the reference architecture for a process control system network and its interfaces to a corporate network. The papers objective is to give the reader an understanding of the techniques utilized to securely connect these networks.
Advanced diagnostics, some of which are available today, will go beyond alarming transmitter
failures to actually predict impending failures in the complete measurement system. This will
significantly reduce unscheduled shutdowns, and also reduce the risk of onscale failure.
This white paper discusses SONAR-based, clamp-on gas volume fraction meters which recently have been introduced to the industry that provide an accurate, real time, measurement of entrained gases. Coupling entrained gas volume fraction monitor with most types of process density meters, enables accurate determination of liquid and the liquid-solid components of aerated mixtures.
Automation designers face many challenges and tradeoffs in the development of a successful network solution. This white paper discusses the necessary choices in selecting a network technology appropriate for various specific applications.
Proven methods for industry to reduce energy consumption and environmental impact are already at hand. These cost-effective solutions promise substantial return-on-investment now and in the future, without sacrificing performance or quality. For most companies and organizations, the answers to maintaining a competitive edge in this era of rising energy costs are readily available. By applying a suite of cost-effective power and automation solutions from technology leaders like ABB, these facilities can achieve substantial energy savings today without waiting for the "alternative fuels" of the future.
In the real world, sharing PCN data with external systems and accessing PCN systems from external
sources is fast becoming a business necessity. This paper provides some generic guidelines for enabling
secure connectivity between PCNs and external systems.
OSHAs Hazard Communication Standard (HCS) is based on a simple conceptthat employees have both a need and a right to know the hazards and identities of the chemicals they are exposed to when working.
