Decentralization with PROFIBUS-DP: Architecture and Fundamentals, Configuration and Use with SIMATIC S7

With its wide variety of connectable field devices, the EN compliant PROFIBUS-DP has advanced into a worldwide accepted and recognized standard as a fieldbus system in the area of distributed I/O. In addition to providing basic knowledge on the topic of PROFIBUS, the book concentrates on the configuration of PROFIBUS-DP using STEP 7, discusses the various methods of data communication with user programs, and gives valuable tips on commissioning and trouble-shooting. A series of practical examples based on SIMATIC programmable controllers helps users put theory into practice.
The 2nd edition describes all functions and applications of PROFIBUS-DP based on version 5 of STEP 7. This includes the "direct" data communication between PROFIBUS-DP slaves (i.e., cross communication) and the equidistant DP bus cycle, both of which are adjustable since version 5. The reader also learns about the factors which determine data transmission times and reaction times. The book?s practice-oriented approach makes it especially valuable to PROFIBUS planners, design engineers and programmers. At the same time, students and teachers may find its fundamental, detailed and comprehensive contents a valuable reference text.
