840Dsl: Ethernet connection
Without further configuration settings being made, communication takes place directly from the PLC GP via the
CP 840D sl. The FB 1 parameters listed below are used for parameterization.
The numeric part of the logical name of the component must be entered in "MCP1 BusAdr", "MCP2 BusAdr" or
"BHGRecGDNo" (corresponds to the bus address of node). The logical name is defined via switches on the MCP
or terminal box.
