2．Terms and Definitions

2. Terms and Definitions

The terms and definitions used in this guide are given below.

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. The term “IO-Link Master Unit" is used to refer to

a specific unit in this guide.

IO-Link Mode A communication mode of an IO-Link master to perform IO-Link

communications with IO-Link devices.

cyclic

communications Communications that exchanges 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 of 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. There are various types of slave units such

as servo drives that handle position data and I/O terminals that handle

bit signals.

node address

An address to identify a slave unit connected to EtherCAT.

4．Overview

4. Overview

This guide describes procedures for: connecting a PATLITE IO-Link Signal Tower LR6-IL

(hereinafter referred to as the "Signal Tower") via IO-Link to an OMRON NX-series IO-Link

Master Unit (NX-ILM□□□); connecting an OMRON NJ/NX-series Machine Automation

Controller (hereinafter referred to as the "Controller") via EtherCAT through an OMRON

EtherCAT Coupler Unit (NX-ECC20□) to which the IO-Link Master Unit is connected; and

checking their communication status.

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 guide, the generic EtherCAT slave for EtherCAT communications is called the "slave

unit", and the specific EtherCAT slave made up of the EtherCAT Coupler Unit and the IO-Link

Master Unit is called the "Slave Terminal".
