Term Description and Definition
IO-Link device A device with a sensor or actuator that can perform IO-Link
communications with the IO-Link Master Unit.
IO-Link Master Unit A device that performs IO-Link communications with the IO-Link
devices in the IO-Link System and simultaneously functions as a slave
for host communications. In this document, IO-Link Master Unit is
used to refer to a specific unit.
IO-Link Mode A communications mode on the IO-Link Master Unit for performing 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 the host.
There are the following two types of data in an IO-Link System.
• Target data in cyclic communications with the host in the IO-Link
Master Unit
• Target data in the IO-Link devices for cyclic communications with the
IO-Link Master Unit
Process Data I/O data in the IO-Link devices. A maximum of 32 bytes of process data
can be allocated in the master.
IODD files These files contain IO-Link device definitions. Parameter settings for
IO-Link devices can be made by loading these files to the CX-
ConfiguratorFDT.
OSSD An output that is turned ON when safety has been confirmed. This is
used for safety applications.

3. Precautions
(1) When developing actual systems, check the specifications of the devices and equipment
that comprise the systems, ensure that devices and equipment are used with sufficient
margin given to ratings and characteristics, and adopt safety measures such as safety
circuits that minimize danger in the event of a malfunction.

4. Introduction
This document describes the procedure for connecting the OMRON Safety Light
Curtain/Multi-Beam Safety Sensor F3SG-SR/PG series (simply referred to as "safety light
curtain" from here on) to the OMRON Machine Automation Controller NX series (simply
referred to as "controller" from here on) via the OMRON Intelligent Tap by the IO-Link
System.
An IO-Link System allows the following possibilities.
●Reading of ON/OFF information and other various information is possible
The controller can cyclically read the following ON/OFF information:
• Input signals and status from IO-Link devices*1
• Disconnections, short-circuits, I/O power supply ON status, etc., between the IO-Link
Master Unit and devices
*1: Examples for photoelectric sensors: unstable detection and sensor errors.
The information from these is called "process data," and this is shared periodically between
the safety light curtain and IO-Link Master Unit.
In this document, a sample program for making checking of the following easier is introduced
in 10.1 Sample Program for Acquiring Process Data.
• Power supply voltage of receiver
●Reading of user-specified data in IO-Link devices from the controller is possible
User-specified data in IO-Link devices can be read from the controller by executing
communications instructions in the controller.
Because an IO-Link System can cyclically read analog data such as the amount of incident light
in addition to ON/OFF information, it can be used for predictive maintenance based on detection
of such things as decreases in the amount of light.
This enables the status of the safety light curtain to be monitored.
The information of these is called "service data," and any information can be acquired from
the safety light curtain by executing communications instructions from the controller when
necessary.
4.1 What Is an IO-Link System?
Additional Information
This document describes the connection procedure up to establishment of
communications on the IO-Link System. It does not describe operation, installation and
wiring of safety I/O functions such as OSSD, and the functions and operations of devices.
For details on safety I/O functions, refer to the manuals, instruction sheets and other
documentation for the safety controllers, or contact OMRON.

4. Introduction
5
In this document, sample programs for making checking of the following easier are
introduced in 10.2 Sample Program for Acquiring Service Data (Error Code) and 10.3 Sample
Program for Acquiring Service Data (Amount of Incident Light).
• Acquisition of error codes
• Acquisition of amount of incident light
●Item required for connection via an IO-Link System
The Intelligent Tap (F39-SGIT-IL3) is required for connecting the safety light curtain to the IO-
Link Master Unit.
In addition to an IO-Link System connection function, the Intelligent Tap has functions such
as changing safety light curtain settings and for restoring backed up settings by means of DIP
switches.
Intelligent Tap (F39-SGIT-IL3)
●Separate use of safety I/O functions and IO-Link System
Safety I/O functions are used mainly for safety applications such as OSSD. On an IO-Link
System, these functions monitor the various data of the safety light curtain.
Connect each of the safety I/O functions and IO-Link System as follows.
Do not use output signals from an IO-Link System for safety applications.
Malfunction of the F3SG-SR/PG might result in serious injury.
