840D: MPI connection
If an MPI connection is used for the MCP and HHU, these components must be taken into
account in the configuration for global data in STEP7 (NetPro). Although the addresses of
the MCP and HHU can be stored anywhere, we recommend a free input and output image
area. These start addresses must also be stored in the pointer parameters of the FB1. The
FB1 parameters listed below are used for further parameterization.
Setting MCP1Stop, MCP2Stop, BHGStop = 1 will suppress time monitoring. MCP failed
interrupts are suppressed.
Once the configuration has been compiled in NetPro, the SDB 210 in the SDB container will
need to be loaded on the PLC.
