The D0-DCM Data Communications Module offers two communication ports for a variety of simultaneous communications possibilities:

• Extra communications ports to connect a PC, operator interface, etc.
• Network interface to DirectNET
• Network interface to a MODBUS network using the RTU protocol

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 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).

H0-ECOM100 Modules

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.

• H0-ECOM100 - 100 Mega baud Ethernet Communications Module for DL05/ DL06 PLCs. 10/100 Mb with auto-detect, supports TCP/IP, UDP/IP, IPX and MODBUS TCP/IP application layer protocol.

NetEdit3 Software

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.

D0-DEVNETS - DeviceNET slave module.

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

• The D0-DEVNETS slave module slides into the option card slot of any DL05 or DL06 PLC.
• The module collects and reports all discrete I/O data to a DeviceNET master.
• The module has a removable connector that makes the four-wire connection easy to implement and maintain.
• It also incorporates advanced diagnostics not commonly found on traditional industrial networks.
• Adds low-cost and small-footprint discrete I/O to an application requiring DeviceNET bus interface

H0-PSCM - Profibus slave communication module.

You can now add a DL05 or DL06 PLC sub-system to a Profibus controller network. The H0-PSCM module allows the DL05 or DL06 PLC sub-system to be linked with a Profibus master controller.

• Profibus is a control bus that provides a common method to connect automation equipment with devices on a single network and significantly reduces hardwiring costs.
• Profibus provides specifications for information exchanged between nodes, such as controller data associated with low level device and configuration parameters that are individually related to system operations.
• The H0-PSCM module transfers blocks of I/O or register memory data between a Profibus master and a DL05 or DL06 PLC. The user can choose up to four blocks of data to be transferred. The data blocks can range in size from 1 byte to 32 words (64 bytes) and can be either input or output data.
