32 Equipment Manual, 03/2023, C79000-G8976-C256-07
Restrictions for CPUs with older firmware versions
• With CPUs with firmware version V4.1, the CP only has the range of functions of the
predecessor module CP 443-1 Advanced (6GK7 443-1EX41-0XE0).
• The use of the program blocks AG_SSEND (FC53) and AG_SRECV (FC63) is only possible
with CPUs as of firmware version V5.1.
• With CPUs with firmware versions up to and including V5.1, no PROFINET IO operation is
possible.
Table of compatible CPUs
The CP is supported by the S7400 CPUs with the article numbers and firmware versions as
shown in the following table.
The table also contains the following information:
• The number of CPs that can be operated with one CPU
• The number of CPU resources for SEND/RECEIVE calls
• CPUs that support the LOCK/UNLOCK function with the FETCH/WRITE services.
• CPUs that support operation of the CP as a PROFINET IO controller.
