Setting Tag Data Links Section 6-2
6-2-2 Tag Data Link Setting Procedure
The section describes the procedure for setting tag data links (i.e., connection
information).
For data links between PLCs, the connection information is set only in the
originator, i.e., the node that receives data.
1. Creating a Network Configuration
Register all EtherNet/IP Units or built-in EtherNet/IP ports for which connections will
be created in the EtherNet/IP Network Configuration Window. (Refer to 6-2-3 Reg-
istering Devices.)
Note If a system has already been installed, connect online to the EtherNet/IP net-
work and upload the network configuration. (Refer to 6-2-11 Uploading Tag
Data Link Parameters.)
↓
2. Creating Connections
Set the connections using one of the following methods.
1) Basic Operation
1-1) Create tags and tag sets for all registered devices (EtherNet/IP Unit or built-
in port). (Refer to 6-2-4 Creating Tags and Tag Sets.)
1-2) Create a connection for the originator device (i.e., registered device that
receives data as input data). (Refer to 6-2-5 Connection Settings.)
2) Generating a Connection Using the EtherNet/IP Datalink Tool (Refer to 6-2-5
Connection Settings.)
The EtherNet/IP Datalink Tool is used to create data links between PLCs by
specifying I/O memory addresses in the same manner as for Controller Link.
The following functions can be used with Network Configurator version 3.10 or
higher.
3) Creating Connections Using the Wizard (Refer to 6-2-7 Creating Connections
Using the Wizard.)
Create connections between OMRON PLCs following the instructions. Tags and
tag sets must be set for all devices before starting the Wizard. (Refer to Basic
Operation 1-1.)
Note Select Device - Parameters - Wizard from the menus to start operation.
4) Creating Connections by Dragging and Dropping Registered Devices (Refer to 6-
2-8 Creating Connections by Device Dragging and Dropping.)
When a target device is dragged and dropped to the originator device, the Edit
Connection Dialog Box will be displayed, and a connection can be created.
OMRON EtherNet/IP Units or built-in EtherNet/IP ports are the only originator
devices for which connections can be created in this way.

Downloading Tag Data Link Parameters (Refer to 6-2-10 Downloading Tag Data Link
Parameters.)
↓
Check that tag data links are operating correctly by using the indicators on the Ether-
Net/IP Unit (refer to 14-2 Using the LED Indicators and Display for Troubleshooting for
Troubleshooting) and the Network Configurator monitor function (refer to 14-1 Check-
ing Status with the Network Configurator).
↓
Check that the output tag data is updated in the input tag by using the CX-Program-
mer's Watch Window or PLC memory function.
Note Refer to the CX-Programmer Operation Manual (Cat. No. W446) for the operat-
ing procedures.
