Microcomputers for Process Control provides an introduction to microprocessor technology for process monitoring and control. The book begins with an overview of microprocessor applications in areas such as consumer products, factories, and telecommunications. This is followed by separate chapters that discuss microcomputer technology; electrical interface to enable plant monitoring and control by microcomputer; microcomputer system hardware and software; VDU-based plant monitoring systems; and methods of computer control. This book is aimed at practicing engineers in industry who wish to acquire a base of understanding of this technology and also to learn how microcomputers can actually be applied in real plant situations. Considerable emphasis is given to plant measurements, interfacing techniques and applications of microcomputers for plant monitoring and control. No prior knowledge of microprocessor technology is assumed, but some awareness of plant measurement and control problems will assist the reader. Students undertaking engineering courses which include microelectronics or process control studies should also find the text helpful.
