7 Using the CP 443−1 Advanced with
PROFINET CBA
To be able to use the CP 443−1 Advanced with PROFINET CBA, you create your
user program with STEP 7 and configure the S7−400 station.
You then configure the interconnections between the PROFINET CBA components
with SIMATIC iMap.
7.1

CBA Interface in the User Program with FB90 or FB88

PN_IO_X (FB90) / PN_InOut (FB88) and Interface DB
The interface to the user program is the interface DB for PROFINET CBA. The
PN_IO_X (FB90) and PN_InOut (FB88) blocks are responsible for transferring
data from the interface DB to the CP and from the CP to the interface DB.
The function blocks FB90 and FB88 behave largely identically on the interface to
the user program. The following applies:
S The interface parameters are identical;
S FB90 has several additional condition codes in the STATUS parameter;
S There are differences in the configuration limits of the interface DB (see Table
5-6).
Please refer to the documentation of the blocks in the online help of STEP 7 or in
the general part of this manual.
If you use the CP with the firmware version V2.2 described here, we recommend
that you use FB90. As a result, you can achieve shorter reaction times. Note the
constraints regarding its use in this manual.
Notice
Replacing blocks:
S
You can replace FB88 in your user program with FB90 without needing to run
the componentization again.
S
If you replace FB90 in your user program with FB88, you will have to repeat the
componentization.
Notice
Only one of the two block types FB88 or FB90 can be used in the user program of
an S7−400 station. Componentization is rejected if both block types are used at
the same time.
