PROFIBUS connection on the MPI/DP port (MCPBusType = 4)
With the PROFIBUS connection of the MCP, this component must be considered in the STEP
7 hardware configuration. The MCP is connected on the MPI/DP bus of the PLC.
The addresses must be stored in the input and output log range. These start addresses must
also be stored in the pointer parameters of the FB1. The FB1 parameters listed below are used
for further parameterization. There is no PROFIBUS version of the HHU. For this reason, an
Ethernet connection is shown for the HHU in this diagram. The PROFIBUS slave address must
be stored in the parameters MCP1BusAdr and MCP2BusAdr. Enter the pointer to the
configured diagnostic address (e.g. P#A8190.0) in MCPxStatRec.
