Preface

Purpose

This manual is your guide to creating user programs in the Function Block Diagram (FBD)

programming language.

The manual also includes a reference section that describes the syntax and functions of the language

elements of Function Block Diagram.

Basic Knowledge Required

The manual is intended for S7 programmers, operators, and maintenance/service personnel.

In order to understand this manual, general knowledge of automation technology is required.

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 XP, MS Windows Server 2003 or

MS Windows 7 are required.

Scope of the Manual

This manual is valid for release 5.5 of the STEP 7 programming software package.

Compliance with Standards

FBD corresponds to the "Function Block Diagram" language defined in the International

Electrotechnical Commission's standard IEC 1131-3. For further details, refer to the table of standards

in the STEP 7 file NORM_TBL.RTF.

Preface

Requirements

To use the Function Block Diagram manual effectively, you should already be familiar with the theory

behind S7 programs which is documented in the online help for STEP 7. The language packages also

use the STEP 7 standard software, so you should be familiar with handling this software and have

read the accompanying documentation.

This manual is part of the documentation package "STEP 7 Reference".

The following table displays an overview of the STEP 7 documentation:

Preface

Online Help

The manual is complemented by an online help which is integrated in the software. This online help is

intended to provide you with detailed support when using the software.

The help system is integrated in the software via a number of interfaces:

• The context-sensitive help offers information on the current context, for example, an open dialog

box or an active window. You can open the context-sensitive help via the menu command Help >

Context-Sensitive Help , by pressing F1 or by using the question mark symbol in the toolbar.

• You can call the general Help on STEP 7 using the menu command Help > Contents or the "Help

on STEP 7" button in the context-sensitive help window.

• You can call the glossary for all STEP 7 applications via the "Glossary" button.

This manual is an extract from the "Help on FBD". As the manual and the online help share an

identical structure, it is easy to switch between the manual and the online help.
