PLC communication is a vital component of any control system. With the many networking options available, including Ethernet and serial, PLC systems need to have adequate ports and protocols. DirectLOGIC 05 micro PLC units contain two built-in serial ports; communication option modules support Ethernet or DeviceNet.
For as little as $112.00, implement advanced networking solutions for the DL05 with our DeviceNet Slave Module, Ethernet Communications Module (10 or 100 MBit). The D0-DCM module supports DirectNet and Modbus (slave) protocols.
New option modules may not be supported by CPUs purchased prior
to the modules release.
Be sure to check for the latest firmware for your PLC. You can refer to the module specification page on our Web site for this information, or find it in our free catalog.
Here is the direct link to the Firmware Upgrade section of our Web site where you can find the firmware revision histories, the latest files and tools required to download the firmware into your CPU.
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.
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.
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.
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).

The H0-ECOM100 Ethernet Communication Modules represent a price breakthrough for high-speed peer-to-peer networking of PLCs. No longer are you forced to designate a single PLC to be the network master. Any PLC can initiate communications with any other PLC. PLC-to-PLC communications are accomplished using Read from Network (RX) and Write from Network (WX) instructions.
The ECOM modules slide into any option card slot of any DirectLOGIC 05 (DL05) or DirectLOGIC 06 (DL06) PLC. Use Category 5 UTP cables which can be run up to 100 meters between nodes. Use repeaters to extend distances and expand the number of nodes.
Free NetEdit3 Software ships with the ECOM Module User Manual. Use NetEdit3 to set up the ECOM modules for your network. Flexible addressing allows you to use your choice of protocols and identifying methods. Assign each module a number or a name or both.

The D0-DEVNETS option card transforms any DL05 or DL06 PLC into a smart device node on your DeviceNET controller network.
