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.
