CJ2M-CPU3xCJ2M CPU with built-in 100Base-TX Ethernet port
CJ1W-ETN1110Base-T Ethernet module for CJ modular PLCs
CJ1W-ETN2110Base-T Ethernet module for CJ modular PLCs
CJ1W-EIP21100Base-TX Ethernet module for CJ modular PLCs
CS1W-ETN0110Base-5 Ethernet module for CS rack mounted PLCs
CS1W-ETN1110Base-T Ethernet module for CS rack mounted PLCs
CS1W-ETN2110Base-T Ethernet module for CS rack mounted PLCs
CS1W-EIP21100Base-TX Ethernet module for CS rack mounted PLCs

The rest of this article uses the name Ethernet Interface to refer to any of the above Ethernet ports or modules.

See Omron Ethernet Guide for information about using Omron PLCs with Ethernet.

Configuring Omron Ethernet Interfaces

CS/CJ Ethernet Interfaces can be configured using CX-Programmer.

Configuring the Ethernet Interface on the CPU unit

To change the settings of the Ethernet Interface on the CPU unit:

1. Open a project in CX-Programmer and in the Workspace window select IO Table and Unit Setup:

CX-Programmer Workspace window with IO Table and Unit Setup selected

2. Double click the IO Table and Unit Setup branch to open the PLC IO Table window. Expand the Built-in Port/Inner Board branch:

CX-Programmer PLC IO Table with built in Ethernet port shown

3. Double click the entry that corresponds to the built in Ethernet port.
