Preface Requirements To use the Statement List 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: Documentation Purpose Order Number STEP 7 Basic Information with Basic information for technical 6ES7810-4CA08-8BW0 • • • Working with STEP 7, Getting Started Manual Programming with STEP 7 Configuring Hardware and Communication Connections, STEP 7 personnel describing the methods of implementing control tasks with STEP 7 and the S7-300/400 programmable controllers. • From S5 to S7, Converter Manual STEP 7 Reference with Provides reference information 6ES7810-4CA08-8BW1 • • Ladder Logic (LAD)/Function Block and describes the programming Diagram (FBD)/Statement List (STL) for languages LAD, FBD, and STL, S7-300/400 manuals and standard and system functions extending the scope of Standard and System Functions the STEP 7 basic information. for S7-300/400 Volume 1 and Volume 2 Online Helps Purpose Order Number Help on STEP 7 Basic information on programming and configuring hardware with STEP 7 in the form of an online help.

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 contextsensitive help via the menu command Help > Context-Sensitive Help, by pressing F1 or by using the question mark symbol in the toolbar. Further Support • 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 Statement List". As the manual and the online help share an identical structure, it is easy to switch between the manual and the online help.
