Introduction to I/O Data and Types of I/O Data

The I/O data is the data for cyclic communications between the IO-Link Master Unit and the controller.
The following types of I/O data are available.
• Process input data from and process output data to each connected IO-Link devices (process da-
*1
ta)
• Digital inputs for pin 2, digital I/O data of the connected IO-Link devices
• IO-Link master status
*1. For the I/O data (process data) of OMRON IO-Link devices, refer to the Index List of the IO-Link devices in
Related Manuals on page 21.

Description
Indicates whether the IO-Link process
input data in IO-Link Mode is valid or
invalid at the controller for each port.
Indicates the error status of the IO-Link
communications processing section.
Indicates the status of the I/O power
supply to the IO-Link Master Unit.
Indicates the following errors for each
port.
IO-Link communications error, short-cir-
cuit in I/O cable, device configuration
verification error, device I/O size error,
PDO mapping error, error-level device
event, and warning-level device event
