Requirements for use
3.2 System environment
Restrictions for CPUs with older firmware versions
● 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 order 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;
● Which CPUs support the LOCK/UNLOCK function with the FETCH/WRITE services:
● Which CPU supports operation of the CP as PROFINET IO controller;
CPU Order number of the
CPU: 6ES7...
