CP 443-1 Advanced (GX30)
Manual, 03/2019, C79000-G8976-C256-05
41
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
443
5 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 a
s 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.
System environment
General requirements

– CPUs with firmware version 4.0 must be upgraded to V4.1.
– CPUs with firmware version 5.0 must be upgraded to V5.1.
● Open TCP/IP communication is supported by all CPUs as of firmware version V4.1.
● The program block PN_InOut_Fast (FB90) for PROFINET CBA is supported by all CPUs
as of firmware version V4.1.
