*1. The IO-Link Master Unit with unit version 1.1 or later is required to use this function.
The following table shows whether or not functions can be used according to the IO-Link Master Unit
type and connection conditions.

This function detects I/O cable breaks, disconnections from
IO-Link device ports, error-level device events, device con-
figuration verification errors, and IO-Link device malfunc-
tions.
This function detects short-circuits in I/O cables.
The controller can use the Input Data Enabled Flags to de-
termine whether the IO-Link process input data for IO-Link
communications is valid.
This function turns OFF outputs from the IO-Link Master
Unit when an error occurs in communications with the con-
troller in IO-Link Mode or in an SIO Mode.
This prevents output operations with incorrect values when
a communications error occurs.
The IO-Link total communications lost frames can be read
from the CX-ConfiguratorFDT.
You can use this function to determine communications sta-
tus as affected by I/O cable noise or other factors.
You can remove the chattering and noise of the input signal
for digital inputs in SIO (DI) Mode or for digital inputs for pin
2 in IO-Link Mode.
When the input data changes without stabilization of the
state of the contact point due to chattering and noise, this
function prevents changes in data and stabilizes it.
In IO-Link Mode, this function reflects the specified bit data
*1
in the input data from the IO-Link device on the digital input
data of the IO-Link Master Unit.
One bit for each IO-Link port can be aggregated.
As a result, the bit data in the input data from the IO-Link
device can be aggregated into the digital input data of the
IO-Link Master Unit.
This function cannot be used in SIO (DI) Mode and SIO
(DO) Mode.
If you are using this function, you cannot perform digital in-
puts for pin 2.
This function is used to back up parameter settings in IO-
Link devices in the IO-Link Master Unit or restore them to
IO-Link devices.
This eliminates the need to set parameters again after re-
placing an IO-Link device.
This function records events, such as errors and status
changes, that occur in the IO-Link Master Unit and IO-Link
devices.
