2. Terms and Definitions
Term Explanation and Definition
IO-Link device
A device with a sensor or an actuator that can perform IO-Link
communications with an IO-Link master.
IO-Link master
A device that performs IO-Link communications with IO-Link devices in
an IO-Link System and that simultaneously functions as a slave for
host communications.
“IO-Link Master Unit” is used to refer to a specific Unit in this document.
IO-Link Mode
A communication mode of an IO-Link master to perform IO-Link
communications with IO-Link devices.
Cyclic
communications Communications that exchange data in a fixed period with no need for
programming.
I/O data
All target data in cyclic communications with a host.
IO-Link Systems contain the following two types of I/O data.
・Target data in cyclic communications with a host in an IO-Link master
・Target data in IO-Link devices for cyclic communications with an
IO-Link master
Process data
I/O data in IO-Link devices. You can allocate a maximum of 32 bytes of
process data in a master.
IODD file
A definition file for an IO-Link device.
The parameter settings for an IO-Link device can be made by installing
this file in CX-ConfiguratorFDT.
Slave unit A generic name for a device that performs EtherCAT communications
with an EtherCAT master in an EtherCAT system. There are various
types of slaves such as servo drives that handle position data and I/O
terminals that handle bit signals.
Node address A node address is an address to identify a unit connected to EtherCAT.
ESI file An ESI file contains information unique to EtherCAT slave units in XML
format. Installing an ESI file enables Sysmac Studio to allocate
EtherCAT slave process data and make other settings.

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 NJ-series Machine Automation Controller (hereinafter
referred to as Controller) via EtherCAT through EtherCAT Coupler Unit (NX-ECC20[]) to which
IO-Link Master Unit is connected and also for checking their connection 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 generic EtherCAT slave for EtherCAT communications is called "slave
unit", and a specific EtherCAT slave configured of EtherCAT Coupler Unit and IO-Link Master
Unit is called "Slave Terminal".
