STEP®7-Crash Course - Extended Edition

The programming language STEP®7 is an advanced development of STEP®5 and it is applied for the controller generation "SIMATIC® S7". The "SIMATIC® S7" is the most widely spread Programmable Logic Controller (PLC) in Europe. This book should help beginners to quickly get used to working with the programming language STEP®7. By means of numerous examples the individual topics are introduced to the reader in detail. The book does not only impart the language of STEP®7, but also the handling of control devices of the S7-300® series.
The chapters Indirect Addressing, Analog Value Processing, Hardware Configuration, Global Data Communication, Profibus DP Configuration, Ethernet Networking and Remote Maintenance are of interest for advanced learners.
Using the demo version of WinPLC7 V4(*) you can reproduce the examples on a Windows-PC. Since the simulation software (Software-PLC) is to be operated just like a real S7-PLC, the reader will simultaneously also practice the handling with a real S7 controller.
An Overview of S7 Instructions, an overview of S7- PLCs and a Glossary in the appendix complete the book.
