ECOM Module Introduction

Several Ethernet Communication (ECOM) modules are currently available for use with

DL05/06, DL205 and DL405 PLC systems. The ECOM modules are shown below. These

modules provide a low-cost, high-speed Ethernet link for PLC systems. The modules are easy

to set up and install on 10/100BaseT (twisted pair, copper wire) or 10BaseFL (fiber optic)

Ethernet networks.

LEDs on the face of each module give vital information about the status of the module and the

communication link. The 10/100BaseT modules use standard RJ45 modular connectors, and

the 10BaseFL modules use ST style bayonet connectors.

NOTE: If you are using a D0-06LCD in your DL06 PLC, the date code for the display unit must be 032A_ or

later to be compatible with the H0 series ECOM modules.

ECOM Communication Possibilities

You can use the ECOM modules to share data between two or more DirectLOGIC PLCs

or between DirectLOGIC PLCs and personal computers. The H0/H2/H4 -ECOM100

additionally allows client/server communications with other Ethernet devices using the

MODBUS TCP protocol. Communication between PLCs/MODBUS TCP devices is

accomplished by using the Read/Write (RX/WX) instructions which are available in the

DirectSOFT Programming Software Users Manual. Chapters 4 and 5 explain the use of the

RX/WX instructions.

NOTE: Please review intelligent instructions (IBox) in Chapter 5 of the user manual for the PLC you are

using, which simplify this and other functions.
