Configuration and operation
6.15 Using the CP for PROFINET CBA
CP 443-1 Advanced (GX30)
88
Manual, 03/2019, C79000-G8976-C256-05
The activities of the program blocks FB90 and FB88 on the interface to the user program are
practically the same. The following points apply:
● The interface parameters are identical;
● For FB90, there are several additional condition codes in the STATUS parameter;
● There are differences in the configuration limits of the interface DB (see section Typical
values and limit values (Page 29)).
Refer to the documentation of the function blocks in the online help of STEP 7 or in the
manual /12/ (Page 120).
Note
Only one of the two program blocks PN_InOut (FB88) or PN_InOut_Fast (FB90) can be used
in the user program of an S7400 station. Componentization is rejected if both block types are
used at the same time.
6.15.2 Preparing for configuration with STEP 7
During configuration, remember the following requirements for subsequent use with
PROFINET CBA:
● Configure the modules for the S7400 station in STEP 7 / HW Config
You can assign the option "Use this module for PROFINET CBA communication" to one
(and one only) CP 4431 Advanced in an S7400 (in the "PROFINET" tab)
In multicomputing, the PROFINET CBA function is handled by the CPU that you assigned
to the CP in the "Addresses" tab.
● Configuration of the PROFINET interface
If you use the S7400 station as a standard component, you will need to make the
following settings when you later configure the PROFINET interface:
Disable the "Set MAC address / use ISO protocol" option.
Note
ISO transport connections and S7 connections using the ISO protocol cannot be operated
when using the S7400 station as a PROFINET CBA standard component!
For more detailed information on adopting the configuration data in the SIMATIC iMap
engineering tool, refer to the documentation on SIMATIC iMap in the references in section
On project engineering of PROFINET CBA (Page 122).
