System function blocks (SFBs) and system functions (SFCs) of the integrated SINUMERIK PLC can be determined using SIMATIC Manager.

Which system function blocks (SFBs) and system functions (SFCs) are provided in SINUMERIK control systems? How can these be determined?

The SFBs/SFCs can differ depending on the type of the integrated PLC-CPU. An overview of the PLC-CPUs used can be found in the following table.

SINUMERIK type Integrated PLC
CCU1, NCU 57x PLC 314
NCU 57x PLC 315
CCU2, NCU 57x.2, NCU57x.3 PLC 315
CCU3, NCU57x.3 PLC 315
CCU3.4, NCU 57x.4 PLC 314-C
NCU 57x.5 PLC 317

For a PLC of SINUMERIK, where a general reset has been carried out, using SIMATIC Manager in the online block overview, all SFBs and SFCs provided for this PLC type can be listed.

You can find general information on this topic in the List Manual "S7-300 Instruction list S7-300 CPUs and ET 200 CPUs" in chapters "System Functions (SFC)" and "System Function Blocks (SFB)".
