Approach to engineering process control systems

A framework for carrying out the implementation of process control systems is described. The framework is applied throughout the project from the process requirements to start-up and ongoing maintenance. This approach, which is based upon a solid functional requirements definition, is applicable to a retrofit or a new project. Equipment selection, systems design, software development, progress monitoring, and engineering aspects are discussed. The author identifies technical engineering rules to be applied in carrying out the project. These rules can be used in the design of a system to meet the application requirements as well as in the project approach and organization. The author lists some pitfalls awaiting those who plan to automate and identifies ways of avoiding them
