Programming with STEP 7
Manual, 05/2010, A5E02789666-01 7
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:
• There are several menu commands which you can select in the Help menu:
The Contents command opens the index for the Help on STEP 7.
• Using Help provides detailed instructions on using the online help.
• 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 by clicking the "Help"
button or by pressing
F1.
• The status bar offers another form of context-sensitive help. It displays a short explanation for
each menu command when the mouse pointer is positioned on the menu command.
• A brief explanation is also displayed for each icon in the toolbar when the mouse pointer is
positioned on the icon for a short time.
If you prefer to read the information from the online help in printed format, you can print out
individual help topics, books, or the entire online help.
This manual, as well as the manuals "Configuring Hardware and Communication Connections
STEP 7", "Modifiying the System During Operation via CiR" and "Automation System S7-400H -
Fault-Tolerant Systems" is an extract from the HTML-based Help on STEP 7. For detailed
procedures please refer to the STEP 7 help. As the manuals and the online help share an almost
identical structure, it is easy to switch between the manuals and the online help.
You can find the electronic manuals after installing STEP 7 via the Windows Start menu: Start >
SIMATIC > Documentation.
