A.1.14 Using loadable blocks for S7 communication for the integrated PROFINET
interface
If you have already used S7 communication via CP with loadable FBs (FB 8, FB 9, FB 12 –
FB 15 and FC 62 with version V1.0) from the SIMATIC_NET_CP STEP 7 library (these
blocks all feature the family type CP300 PBK) and now want to use the integrated
PROFINET interface for S7 communication, you must use the corresponding blocks from the
Standard Library\Communication Blocks STEP 7 library in your program (the corresponding
blocks FB 8, FB 9, FB 12 – FB 15 and FC 62 have at least version V1.1 and family type
CPU_300).
Procedure
1. Download and overwrite the old FBs/FCs in your program container with the
