Ethernet communication
In case of CP 840D the Ethernet address is assigned by default for the port X127. As such, the PLC can be
reached via this port from a STEP 7 project. If needed, the Ethernet address on the CP 840D can be changed to
the Ethernet address of the port X120 or X130. Then a cable connection to the PG of this port is also necessary.
Connection of central I/O-devices
The physical connection for a connection to an IM361 does not exist. No central I/O is possible.
