Using a DCM as part of a PLC Network Slave — The DCM can also be used in a DL405 PLC station that is serving as a network slave station. In this case, the DCM “listens” to the network for any messages that contain the DCM’s address. The DCM deciphers the network commands, carries out the request to read or write data, and sends confirmation and/or information to the master station.
