Components of IO-Link System
Components of IO-Link System and Their Roles
The IO-Link system mainly consists of IO-Link Master, IO-Link devices (such as sensors, actuators, etc.), cables and engineering tools.
IO-Link Master is a terminal unit that performs IO-Link communication with an IO-Link device in an IO-Link system.
IO-Link Master with multiple ports allows point to point bidirectional communication to IO-Link devices. The amount of communication data, response time are not affected by neighboring devices.

IO-Link device is a generic term for sensor and actuator devices designed and manufactured based on the IO-Link standard.
These include a wide variety of FA sensors, switches, RFIDs, and actuators.
All devices have an IODD file that describes device information, which can be read to configure the device independently of the manufacturer.
POINT
As shown in the figure above, the device configuration is simple.
There is no problem as long as you select the IO-Link Master that is compatible with the industrial Ethernet you are using.
Our IO-Link Master compatible with CC-Link IE TSN, CC-Link IE Field, CC-Link IE Field Basic, EtherNet/IP, EtherCAT and Modbus TCP.

Required Components for IO-Link
O-Link is an industrial interface standard (IEC 61131-9) that connects sensors and actuators. This communication technology enables the exchange of various types of data, which have been managed manually one by one, at the sensor level in line with IIoT.
-
IO-Link Master
It acts as a gateway between IO-Link devices and host industrial Ethernet.
-
IO-Link Device
It refers to sensors and actuators with an IO-Link communication interface.
*16 million IO-Link compatible devices as of the end of 2019 -
Standard sensor cable
Cable to connect IO-Link device and IO-Link Master.
A standard sensor cable can be used for IO-Link communication, eliminating the need for a dedicated communication cable. -
Setup Tool and Files
Engineering toolPLC programming tools provided by PLC manufacturers.
Can be used for setting up IO-Link Master and device connected to PLC.
*Some items cannot be set. -
IODD file
IODD (IO Device Description) files are provided from each IO-Link device manufacturer.
A file that contains information on device descriptions and parameter such as vendor name, model number, and functions of the IO-Link device.
