Classic Modules

This document should provide an overview of the SIMATIC S7-300 automation system and the associated STEP 7 programming software. As the fundamental principles are laid down in this appendix, there are no special requirements.

In this appendix, the reader obtains information on the international standard IEC 61131. As these are theoretical principles, there are no special preconditions.

This appendix provides the reader with a collection of the most important programming instructions that are required for performing the programming tasks in all the modules. In order that the commands and programming method can be understood, this requires knowledge of the fundamentals of PLC programming (e.g. Appendix I: Fundamentals of PLC programming with SIMATIC S7-300).

This module gives a general overview of fieldbus systems and describes the integrated bus systems of the S7-300 automation system, MultiPoint Interface (MPI), AS-Interface and PROFIBUS.

This appendix provides the reader with an introduction to the Ethernet or Internet technologies that are required in order to understand modules E1-E3.
