Preface

Purpose of the manual

The present manual is intended for persons involved in the areas of configuration,

commissioning and servicing of programmable logic control systems.

To help you get familiar with the product, we recommend that you start with the

example in Chapter 3. It shows you an easy method of getting started on the

subject of fault-tolerant systems.

Basic knowledge required

In order to understand the manual, you will need to be familiar with the general

principles of automation technology.

Knowledge of S7 programs is also a prerequisite; you can read more about S7

programs in the Programming with STEP 7 manual. As you need the STEP 7

standard software while you are configuring, you should also be familiar with

running the standard software, as explained in the STEP 7 User Manual.

Target Group

This manual is aimed at people with the required qualifications to commission,

operate and maintain the products described.

Validity of the manual

The manual is relevant to the following components:

•CPU 414-4H as of firmware version V3.1

•CPU 417-4H as of firmware version V3.1

•Optional package “S7 H Systems” beginning with Version 5.2

Online Help

In addition to the manual, detailed support on how to use the software is provided

by the online Help system integrated in the software.

The Help system can be accessed using a number of interfaces:

•The Help menu contains a number of commands: Contents opens the Help

index. You will find help on fault-tolerant systems at Call Help on options

packages, configuring fault-tolerant systems.

•How to Use Help provides detailed instructions on how to use the online help

system.

•Context-sensitive Help provides information on the current context - for

example, on an open dialog box or an active window. It is accessed by means

of the “Help” button or F1.

•Another form of context-sensitive Help is the status bar. A brief explanation of

each menu command is displayed here when you place the mouse pointer on a

command.

•A brief explanation of the toolbar buttons is also shown when the mouse pointer

comes to rest for a short time on the buttons.

If you would like to read information from online Help in printed form, you can print

individual topics, books or the entire Help.

Finding Your Way

To help you find special information quickly, the manual contains the following

access aids:

•At the start of the manual you will find a complete table of contents and a list of

the diagrams and tables that appear in the manual.

•An overview of the contents of each section is provided in the left column on

each page of each chapter.

•You will find a glossary in the appendix at the end of the manual. The glossary

contains definitions of the main technical terms used in the manual.
