6 Using the CP for PROFINET CBA

To be able to use the CP with PROFINET CBA, you create your user program with

STEP 7 and configure the S7-300 station.

You then configure the interconnections between the PROFINET CBA components

with SIMATIC iMap.

Notice

Operation under PROFINET CBA, is supported only via the PROFINET interface.

The following information on configuration therefore relates only to the

configuration of the PROFINET interface.

Notice

Simultaneous operation of PROFINET CBA and PROFINET IO device is not

possible and is prevented in the configuration in STEP 7.

6.1 CBA interface in the user program with FB88

PN_InOut (FB88) and interface DB

The interface to the user program is the interface DB for PROFINET CBA. The

task of function block PN_InOut (FB88) is to transfer data from the interface DB to

the CP and from the CP to the interface DB.

Please note the documentation of the function blocks in the online help of STEP 7

or in the manual /63/.

6.2 Preparing for configuration with STEP 7

During configuration, remember the following requirements for subsequent use

with PROFINET CBA:

S Configure the modules for the S7-300 station in HW Config

You create one CP 343-1 (and one only) in an S7-300 station.

S Configuring the PROFINET interface

If you use the S7-300 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.
