840Dsl: PROFIBUS connection on the DP port
In case of PROFIBUS connection of the MCP, this component must be considered in the hardware configuration
setting of STEP 7. The MCP is connected to the standard DP bus of the PLC (not to MPI/DP). 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 variant of the HHU. For this reason, an Ethernet connection is shown for the HHU in this
figure. The Profibus slave address must be stored in the parameter "MCP1BusAdr" and "MCP2BusAdr". Enter
the pointer to the configured diagnostic address (e.g. P#A8190.0) in "MCPxStatRec".
