S7 F/FH Systems permits complete integration of safety engineering into the SIMATIC PCS 7 process control system. The Basic Process Control System (BPCS) and Safety Instrumented System fuse together to form a uniform and innovative complete system. The advantages of this fusion are quite clear:

• One common controller platform
• One common engineering system
• No separate safety bus – standard and safety-related communication take place on the same fieldbus (PROFIBUS with PROFIsafe)
• Mixed operation of standard and safety-related I/O modules in remote I/O stations
• Uniform data management – no complex data exchange between BPCS and safety system
• Integration of safety-related applications into process visualization on the operator station
• Automatic integration of safety-related fault messages with time tagging into the process control system
• Integration of safety-related hardware into the SIMATIC PCS 7 asset management for diagnostics and preventive maintenance

Using the S7 F Systems engineering tool, you can parameterize the AS 412F/FH, AS 414F/FH and AS 417F/FH automation systems as well as the safety-related F-modules of the ET 200 I/O systems.

Alternatively, the S7 F Systems engineering tool can also be used with STEP 7 incl. the CFC option package.

Using Continuous Function Charts (CFC) and predefined function blocks from the F-block library of S7 F Systems, you can configure safety-related applications simply, efficiently and without any time-consuming familiarization.

However, this is even simpler, more convenient and faster using the SIMATIC Safety Matrix based on CFC. The configuration tool functioning according to the principle of a Cause&Effect matrix automatically creates complex safety programs once you have assigned the events (causes) occurring during a process to exactly defined reactions (effects).
