Understanding Distributed Processor Systems for Controls - Samuel M. Herb

Understanding Distributed Processor Systems for Controls explains how modern control systems manage industrial processes. It guides readers through the purpose of control systems, the hardware and software components inside controllers and how operators interact with plants using video displays and human-machine interfaces. It balances explanations of older technologies still in use with the rapidly changing innovations shaping today's systems, emphasizing that the true goal is improved plant productivity, not just impressive features.

This book covers the process of planning, specifying, selecting and implementing a control system, including vendor comparison, testing and project management. It also examines human factors, such as how operators perceive information, design principles for clear screens and alarms, and methods to make interfaces intuitive and safe. Technical ideas are presented clearly so that engineers, managers, technicians, and newcomers (including non-engineers) can ask the right questions and make better decisions about control systems.
