840D: Profibus connection
With an MCP Profibus connection, these components must be considered in the STEP 7
hardware configuration. The MCP may only be interfaced with the standard DP bus on the
PLC (not on 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".
