2. Terms and Definitions

Term Explanation and Definition

Node Controllers and devices are connected to the EtherNet/IP network via the

EtherNet/IP ports. The EtherNet/IP recognizes each EtherNet/IP port

connected to the network as one node.

When a device with two EtherNet/IP ports is connected to the

EtherNet/IP network, the EtherNet/IP recognizes this device as two

nodes.

The EtherNet/IP achieves the communications between controllers or the

communications between controllers and devices by exchanging data

between these nodes connected to the network.

Tag A minimum unit of the data that is exchanged on the EtherNet/IP network

is called a tag. The tag is defined as a network variable or as a physical

address, and it is allocated to the memory area of each device.

Tag set In the EtherNet/IP network, a data unit that consists of two or more tags

can be exchanged. The data unit consisting of two or more tags for the

data exchange is called a tag set. Up to eight tags can be configured per

tag set for OMRON controllers.

Tag data link In the EtherNet/IP, the tag and tag set can be exchanged cyclically

between nodes without using the user program. This standard feature on

the EtherNet/IP is called a tag data link.

Connection A connection is used to exchange data as a unit within which data

concurrency is maintained. The connection consists of tags or tag sets.

Creating the concurrent tag data link between the specified nodes is

called a "connection establishment ". When the connection is

established, the tags or tag sets that configure the connection are

exchanged between the specified nodes concurrently.

Originator and

Target To perform tag data links, one node requests the opening of a

communications line called a "connection".

The node that requests opening the connection is called "originator", and

the node that receives the request is called a "target".

Tag data link

parameter The tag data link parameter is the setting data to perform the tag data

link. It includes the data to set tags, tag sets, and connections.

3. Precautions

4. Overview

This document describes the procedure for connecting CJ2 Programmable Controller +

EtherNet/IP Unit (hereinafter referred to as the PLC) of OMRON Corporation (hereinafter

referred to as OMRON) to NJ-series Machine Automation Controller (hereinafter referred to as

the Controller) via EtherNet/IP and provides the procedure for checking their connection.

It also contains the procedure for performing EtherNet/IP tag data link using the EtherNet/IP

settings of the project file that is prepared beforehand (hereinafter referred to as the

"procedure for using the configuration files").

Section 9 A-1 and Section 10 A-2 describe the procedures for setting parameters with

software without using files (hereinafter referred to as the "procedure for setting parameters

from beginning".

To follow the "procedure for using configuration files", obtain the latest "Sysmac Studio project

file" and "Network Configurator v3 network configuration file" (they are referred to as

"configuration files") from OMRON in advance.
