Requirements for use
3.1
Configuration limits
When using the CP type described here, the following limits apply:
● Number of operable CPs within a rack: 14
● Number of CPs operating as PROFINET IO controllers within an S7 station: 4
● Number of CPs that can be configured for PROFINET CBA communication within an S7
station: 1
Note
Number of CPs operating as PROFINET IO controllers
The number of CPs operating as PROFINET IO controllers depends on the number of CP
4435 Extended modules operating as DP masters in the S7400 station. A total of 10 CPs
can be operated as controllers for the distributed I/O (PROFINET IO controllers or DP
masters); of those, however, only up to 4 as PROFINET IO controllers.
Note the following regarding multiprocessor mode: When operating the CP as a
PROFINET IO controller, only the process image of the assigned CPU can be distributed
via the CP.
