DL05 PLC - Communications and Networking

Connectivity to the Most Popular Networks

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.

D0-DCM Data Communications Module offers two communication ports for a variety of simultaneous communications possibilities
H0-ECOM100 Ethernet Communication Modules represent a price breakthrough for high-speed peer-to-peer networking of PLCs
D0-DEVNETS DeviceNet Module transforms any DL05 or DL06 PLC into a smart device node on your DeviceNET controller network

NOTES:

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.

DL05/06 Data Communications Module

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).

Communication Modules

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

Converters and Cables

The DirectLOGIC 05 (DL05) programmable logic controller (PLC) offers the following accessories for converting RS232 to RS422 or RS422/485 and for simple RS232C networking:

FA-ISOCON - Universal, isolated RS232C to RS422/ RS485 converter.
Switch selectable for ANTE (Automatic Network Transmitter Enable) or RTS/CTS handshaking, works with all DirectLogic PLC families and virtually any serial device. Isolation reduces network data problems caused by noisy environments. Power directly from the 5 V pins on most DirectLogic CPU ports, from a PLC base 24 VDC power supply, or from an external power supply. Cables and connectors to most COM ports (RJ12, DB9-female, DB25-male) provided. Integral DIN rail clamp or can be panel mounted. Manual included with product.
F2-UNICON - RS232C to RS422 converter. Converts RJ12 RS232C port to a DB25 male RS422 port. Powered directly from the 5 V pins on most DirectLOGIC CPU ports. Includes 1 ft. cable with two RJ12 6P6C plugs, and DIN rail mounting kit. Includes manual with product. NOTE: The F2-UNICON provides no signal isolation, so it is not recommended for noisy industrial environments.
FA-UNICON - In-line, DB25, RS232C to RS422/ RS485 converter. Connectors provided for the D3-422-DCU and to connect a DirectLOGIC RJ11/ RJ12 RS232C port to a DB25 female RS422/ RS485 connector. Power directly from the PLC base 24 VDC supply or an external power supply. Connection to a PC RS232 COM port requires a custom cable. A pin 4-20 jumper is required on the FA-UNICON for DB9. NOTE:The FA-UNICON provides no signal isolation, so it is not recommended for noisy industrial environments.
D0-CBL - 12 foot (3.66 m) RS232 shielded networking cable without RTS connections for DL05, D4-450, RJ12 networking ports. RJ12 6P6C to RJ12 6P6C connectors. Enables simple RS232C networking of TWO of the listed PLCs together.
