Preface

Purpose of the Manual

This manual provides you with a complete overview of programming with

S7-GRAPH. It supports you during the installation and setting up of the software. It

includes explanations of how to create a program, the structure of user programs,

and the individual language elements .

The manual is intended for persons with the appropriate qualifications who are

involved in programming, configuration, commissioning, and service of

programmable logic controllers.

We recommend that you familiarize yourself with the example in Chapter 3

"Designing a Sequential Control System Based on the Example of a Drill".

This will help you to get to know S7-GRAPH quickly.

Required Experience

To understand the manual, you should have general experience of automation

engineering.

In addition to, computer literacy and the knowledge of other working equipment

similar to the PC (e.g. programming devices) under the operating systems

MS Windows 2000 Professional or MS Windows XP Professional are required.

Since S7-GRAPH is a component of the STEP 7 basic software, you should have

knowledge of the basic software conveyed in the "Programming with STEP 7 V5.x"

manual.

Scope of the Manual

The manual is valid for the S7-GRAPH V5.3 software package.

Preface

Manual and Online Help

This manual is an extract from the Online Help. The manual describes the basic

knowledge you require to work with S7-GRAPH. The online help contains detailed,

step-by-step instructions and reference sections. Since the manual and online help

have the same structure, you can change easily between manual and online help.

Access to Online Help

The help system is integrated in the software with several interfaces:

•

The Help menu provides numerous menu commands: Contents opens the

contents of the S7-GRAPH help system. Introduction provides an overview of

programming with S7-GRAPH. Using Help provides detailed instructions on

working with the online help system.

•

The context-sensitive help system provides information about the current

context, for example help on an open dialog box or active window. This can be

displayed by clicking the "Help" button or pressing the F1 key.

•

The status bar is another form of context-sensitive help. A brief explanation of

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

a menu command.

A brief explanation of the buttons in the toolbar is also displayed if you position

the mouse pointer briefly over a button.

If you prefer to have a printout of the information in the online help system, you can

print individual topics, books or the entire help system.
