Overview - Omron CJ2-CPU Connection Manual

4. Overview

This document describes the procedures for connecting E3Z-series IO-Link Photoelectric
Sensor (hereinafter referred to as Photoelectric Sensor) that is connected via IO-Link to
IO-Link Master Unit (NX-ILM[][][]) to CJ-series Programmable Controller + EtherNet/IP Unit
(hereinafter referred to as PLC) via EtherNet/IP through EtherNet/IP Coupler Unit
(NX-EIC202) to which IO-Link Master Unit is connected and also for checking their
communication status - all of which are produced by OMRON Corporation.
Refer to Section 6. Communications Settings and Section 7. IO-Link Connection Procedure to
understand setting methods and key points to perform cyclic communications in the IO-Link
system.
In this document, a specific EtherNet/IP slave configured of EtherNet/IP Coupler Unit and
IO-Link Master Unit is called "Slave Terminal".
Also, CJ-series EtherNet/IP Unit and the built-in EtherNet/IP port of CJ-series CJ2 CPU Unit
are collectively called "EtherNet/IP Unit''.
