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 corresponding blocks from the standard library.

2.Update the corresponding block calls, including updating the instance DBs, in your user program.
