A.3 Check List Of The Certified F-Blocks - Siemens SIMATIC S7 F Manual

A.3 Check List of the Certified F-Blocks

Only the F-Blocks listed below can be used to program the F user program. These
blocks are fail-safe and certified.
Please compare the signature and initial value signature of these F-Blocks with
those in the current Annex 1 of the report for the "Safety-Related Programmable
Systems SIMATIC S7-400F and S7-400FH" certificate.
If the initial value signature is not in the printout of the safety program, the
signature must be compared with the CRC in Revision 1.0 of Annex 1 and checked
in SIMATIC Manager to see if the F FB is Version 1.0.
