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
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".
