2 Requirements for Use
Configuration Limits
When using the CP type described here, the following limits apply within a rack:
S Max. number of CPs: 14
S Number of CPs operating as PROFINET IO controllers: 4
S Number of CPs that can be configured for PROFINET CBA communication
within an S7 station: 1 (system property)
Notice
S 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
S7−400 station. A total of 10 CPs can be operated as PROFINET IO
controllers or DP masters; of these, up to 4 can be operated as PROFINET IO
controllers.
S When operating the CP as a PROFINET IO controller, multiprocessing is not
supported; in other words, only process image of the assigned CPU can be
distributed over the CP.
System Environment
The CP 443-1 Advanced is supported by the S7-400 CPUs and CPU operating
systems with the order numbers as shown in the following table.
S The function block FB90 (PN_InOut_Fast) for PROFINET CBA is supported
with all CPUs as of version V4.1.
S Open TCP/IP communication is supported with all CPUs as of version V4.1.
The table also contains the following information:
S The number of CPs that can be operated with one CPU
S The number of AG_SEND or AG_RECV calls that can be used at the same
time on the SEND/RECEIVE interface
S Which CPUs support the LOCK/UNLOCK function with the FETCH/WRITE
services
S Which CPU supports operation of the CP as PROFINET IO controller;
