When the ON/OFF status of an external output cannot be changed
When the ON/OFF status of an external output cannot be changed, check the following items.
Check item
Is the I/O PW LED turned on?
When External output signal (RY0 to RY1F) is
turned on, is the corresponding LED (Y0 LED to
Y1F LED) of the I/O module turned on?
When External output signal (RY0 to RY1F) is
used, is the synchronous X/Y control mode set
for the CC-Link IE TSN Network synchronous
communication setting?
Are signals output from the output terminal Y on
which the LED (Y0 LED to Y1F LED) is on?
Is the inter-module synchronous interrupt
program created when the CC-Link IE TSN
Network synchronous communication function is
used?
When the CC-Link IE TSN Network synchronous
communication function is used, does the master
station used support that function?
Has "Network Synchronous Communication" of
the network configuration setting or the CC-Link
IE TSN Network synchronous communication
setting been changed, to use the synchronization
cycle timing control mode or the set time
synchronization control mode?
Is RWw10 to RWw8F set for the refresh device
setting when the synchronization cycle timing
control mode or the set time synchronization
control mode (CC-Link IE TSN Network
synchronous communication function) is used?
Is the value set in Synchronization output timing
setting Y OFF to ON/ON to OFF (RWw10 to
RWw8F) appropriate when the synchronization
cycle timing control mode (CC-Link IE TSN
Network synchronous communication function)
is used?
Is the output set to turn on or off at an interval
shorter than the maximum output response time
when the synchronization cycle timing control
mode (CC-Link IE TSN Network synchronous
communication function) is used?
Is the time set based on the CPU module clock
when the set time synchronization control mode
(CC-Link IE TSN Network synchronous
communication function) is used?
Is there any problem with other equipment such
as the master station and connected devices?
When CC-Link IE TSN/CC-Link IE Field diagnostics cannot be performed
When CC-Link IE TSN/CC-Link IE Field diagnostics cannot be performed, check the following items.
Check item
Is the version of the engineering tool supported?

11.4 Troubleshooting by Symptom
Action
Refer to the following.
Page 197 When the I/O PW LED does not turn on
If the above LED is not turned on, check and correct the refresh parameter so that the refresh device
setting matches the corresponding setting in the program. For the refresh parameter setting, refer to the
following.
User's manual for the master station used
There is a problem with the CC-Link IE TSN Network synchronous communication setting. When using
External output signal (RY0 to RY1F), set the synchronous X/Y control mode for the CC-Link IE TSN
Network synchronous communication setting. After changing the CC-Link IE TSN Network synchronous
communication setting, power off and on the module power supply or perform remote reset.
If signals are not output, there is a problem with the output wiring.
Check the wiring confirming that the output wiring is not disconnected or short-circuited.
Refer to the following as well.
Page 204 Troubleshooting for output circuit
Create the inter-module synchronous interrupt program when the CC-Link IE TSN Network synchronous
communication function is used.
User's manual for the master station used
When using the CC-Link IE TSN Network synchronous communication function, use the master station that
supports the function. To check the master station supporting the function, refer to the following.
Page 157 Applicable version
When using the synchronization cycle timing control mode or the set time synchronization control mode
(CC-Link IE TSN Network synchronous communication function), perform the following.
• Set "Network Synchronous Communication" to "Synchronous".
• Check and correct the CC-Link IE TSN Network synchronous communication setting.
Power off and on the module power supply or perform remote reset after changing the CC-Link IE TSN
Network synchronous communication setting.
There is a problem with the refresh device setting. Check and correct the refresh parameter so that the
refresh device setting matches the corresponding setting in the program.
Set a value between 0 and "Synchronization cycle - 4s" for Synchronization output timing setting Y OFF
to ON/ON to OFF (RWw10 to RWw8F). ( Page 243 Synchronization output timing setting)
If the output is set to turn on or off at an interval shorter than the maximum output response time, the actual
output may not turn on or off.
Correct the value in Synchronization output timing setting OFF to ON/ON to OFF (Y0 to Y1F) so that the
interval becomes longer than the maximum output response time.
Do not use the CPU module clock for the set time synchronization control.
Set Output time setting based on the input change time (network clock) acquired from the input module.
( Page 244 Output time setting)
If there is no problem with other equipment, the possible cause is an I/O module failure. Please consult
your local Mitsubishi representative.
Action
Check the version of the engineering tool, and if it is prior to the compatible versions, update it.
