"Decentralization with PROFIBUS DP/DPV1: Architecture and Fundamentals, Configuration and Use with SIMATIC S7
by Josef Weigmann, Gerhard Kilian
Thanks to its broad range of connectable field devices, PROFIBUS DP has (in distributed I/O) acquired the status of an internationally acknowledged standard fieldbus system. In addition to imparting a basic knowledge of PROFIBUS, the book concentrates on configuring PROFIBUS DP with STEP 7, explains various methods of data interchange with user programs and provides useful advice on commissioning and troubleshooting.
With its practical orientation the book is ideal for PROFIBUS planners, configuration experts and programmers. Its comprehensive description of the fundamentals involved also makes it interesting for students and docents alike.
For this second edition, the chapter on user program interfaces has been enlarged and the overall content revised in line with the expansions that have taken place in DPV1. The new functions and applications of PROFIBUS DP in SIMATIC S7 on the basis of STEP 7 Version 5.1 SP3 are described, along with setting of an equidistant DP bus cycle and the new signals "Status Alarm", "Update Alarm" and "Manufacturer-Specific Alarm".
