Data communications module for DL205 PLC
If additional communication ports are needed, they can easily be added by installing DCM modules.
The D2-260, D2-250-1, and D2-240 CPUs support the D2-DCM Data Communications Module, which can serve as a DirectNet master/slave, DirectNet peer, or a MODBUS RTU slave.
The D2-DCM supports both RS232C and RS422. You can program the CPU through the DCM locally, or if a PC is the RS422 master, you can use DirectSOFT6 to program any PLC on the network.
Note: The D2-DCM module is not supported by the Do-more H2 CPUs
