2. Terms and Definitions

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

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.

(2) To ensure the safe use of systems, be sure to obtain the manuals, instruction sheets and

other documentation for the devices and equipment that comprise the systems, and check

Safety Precautions, Precautions for Safe Use and other safety related precautions before

using the system.

(3) It is up to the customer themselves to check the ratings and regulations or standards that the

system must comply with.

(4) No part of this publication may be reproduced, stored in a retrieval system, or redistributed,

in any form, or by any means, mechanical, electronic, photocopying, recording, or

otherwise, without the permission of OMRON Corporation.

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

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.
