Terms and Definitions

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.

Overview

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".
