Audience

Scope of the Manual Standards

Installation and Authorization of the Software Structure of the Manual

This manual has the following aims:

S To explain the basic concepts of the standard software S To introduce its most important functions

The software used to configure and program the SIMATIC S5 programmable logic controllers was developed according to modern ergonomic principles. Handling the software is therefore easy to learn and to a large extent self-explanatory.

When procedures are explained, you will find the relevant menu commands are also described. However, instructions on how to fill out dialog boxes are not included since this is explained in online help.

This manual is intended for installation personnel, programmers, and service personnel who have little or no experience of working with the software package STEP 5/ST version 7.0.

This manual is valid for the STEP 5/ST programming software, version 7.0. It is valid for the STEP 5 Standard software package and is the basis for the optional software packages.

The STEP 5 software complies with the International Electrotechnical Commission's standard IEC 1131-3 (or EN 61131-3) for programming languages used with programmable controllers.

Installing the STEP 5 software and transferring the authorization to hard disk is described in this manual. Please refer to Chapter 3 or the readme file for detailed information.

This manual is divided into the following parts:

S Part 1 contains general information on terminology, basic handling of

the standard STEP 5/ST software, and on preparing for a programming session. You should read the first four chapters before you start working with the software.

S Part 2 describes how to work with the language editors. S Part 3 describes testing, handling and documenting projects. S Part 4 describes working with special SIMATIC S5 programs. S To familiarize you with STEP 5/ST more quickly and to illustrate a

practical application, Part 5 contains a sample application. Based on the task of controlling a carwash, the sample project guides you step by step through editing, testing, documenting, and archiving a user program.

S Part 6 introduces you to data managment within STEP 5/ST.

If you have already created a small project and gained some experience, you can read each chapter separately as and when you require information on the topic it covers.

References to other manuals are shown as reference numbers between slashes /.../. Using these numbers you can check the exact title of the manual in the list of references at the end of this manual.
