840D sl: PROFIBUS connection on the MPI/DP port
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 parameter assignment.
There is no PROFIBUS variant 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 MCP1BusAdr and MCP2BusAdr. Enter the pointer
to the configured diagnostic address (e.g. P#A8190.0) in MCPxStatRec.
