|The D0-DCM Data Communications Module offers two communication ports for a variety of simultaneous communications possibilities:|
The top RJ12 RS232 port can be used for PLC programming, connection to an OI panel or as a single DirectNet or K-sequence slave. The 15-pin front port can be used for either RS232/422/485 communications and supports the following protocols: K-sequence slave, DirectNet master/slave, MODBUS RTU master/slave.
- Extra communications ports to connect a PC, operator interface, etc.
- Network interface to DirectNET
- Network interface to a MODBUS® network using the RTU protocol
Extra communication ports
If additional communication ports are needed, they can easily be added by installing DCM modules. This allows additional connections of devices, such as operator interfaces, PCs, etc.
DirectNet network interface
The DCM can be used as a network interface for applications requiring data to be shared between PLCs, or between PLCs and an intelligent device such as a host PC. The DCM connects easily to DirectNET.
MODBUS RTU interface
The DCM can be used as a master or slave station interface to connect your DL05/06 system to a MODBUS® network using the MODBUS RTU protocol. Port 2 on the DCM allows the DL05/06 to function as a MODBUS RTU network master or slave using RS-422 or RS-485 communications (RS-232 can be used for single slave networks).
