■

The engineering tool S7 F Systems integrated in the SIMATIC 

Manager can be used to configure an F system (F/FH). With this 

tool you can: 
• Parameterize CPU and F-signal modules
• Create safety-related applications in the CFC.
Predefined, TÜV-approved blocks are available for this purpose. 

The safety-related blocks save the user having to perform redun-

dant programming for detecting and reacting to errors. 

■

S7 F Systems supports configuration by means of functions for 
• Comparison of safety-related F-programs
• Recognition of changes in the F-program using the checksum
• Separation of safety-related and standard functions.
Access to the F-functions can be password-protected.
The F-block library integrated in S7 F Systems contains pre-

defined function blocks for generation of safety-related applica-

tions with the CFC or the SIMATIC Safety Matrix based on it. The 

certified F-blocks are extremely robust and intercept program-

ming errors such as division by zero or out-of-range values. They 

avoid the need for diverse programming tasks for detecting and 

reacting to errors.

With a S7 F Systems Upgrade from V5.x to V6.0, the type of S7 F Systems 

license changes from single license to floating license.

■

When using the safety-related SM 326F/336F I/O modules (AI, 

DI, DO) as standard I/Os (without F-functionality), an S7 F Con-

figurationPack is required for engineering. This is included in 

S7 F Systems V6.0, and is also available on the Internet for 

downloading.
