Digital communication confronts us every day in modern process engineering: - it is used for configuring and setting the parameters for microprocessor instruments- serial bus systems, with minimum wiring requirements, are able to acquire a large amount of decentralized information and distribute it to the process equipment. Intelligent field and automation devices can communicate directly with one another via a digital bus.This book is intended as a step-by-step introduction to the subject of digital communications, for practical engineers and those new to this field. The emphasis is on clarifying generalized topics, as well as including some JUMO-specific applications.In this revised edition, the material on bus systems has been extensively updated....
