When the ON/OFF status of an external input cannot be read in SIO mode
Check item
Does the CH LED of the relevant channel of the IO-Link module turn on
when the external input device turns on?
Is Remote READY (RWr0.b11) on?
Is Device replacement status (address: 299DH) off?
Is the refresh device set correctly?
Is the operation mode set correctly?
Is the input OFF delay function used correctly?
When the ON/OFF status of an external output cannot be changed in SIO mode
Check item
Does the CH LED of the relevant channel of the IO-Link module turn on
when CH CQ output signal (RY0 to RY7) turns on?
Is Remote READY (RWr0.b11) on?
Is Device replacement status (address: 299DH) off?

11.3 Troubleshooting by Symptom
Action
If the LED does not turn on, there is a problem on the input wiring.
Check the wiring confirming that the input wiring is not disconnected or short-
circuited, or the voltage of the input signal is correct.
For details on the rated input voltage, refer to the following.
Page 16 Performance Specifications
Check that Operating condition setting request flag (address: 2D07H) is off. If
Operating condition setting request flag (address: 2D07H) is on, turn it off and
check that Remote READY (RWr0.b11) is on.

condition setting completion flag
Input is off during device replacement.
Specify the relevant channel in "Write Value" of "Device Changeout Complete"
of "Command Execution of Slave Station".
Page 99 Device Replacement Function
Check the refresh parameter and correct the setting of the refresh device so
that it matches with the setting in the program. For the setting of the refresh
parameters, refer to the following.
 User's manual for the master/local module used
Check that the operation mode matches that of the external input device, and
correct it if necessary. For details on the operation mode setting, refer to the
following.
Page 168 Operation mode setting
When the input OFF delay function is enabled, Remote input signal (RX) turns
off after the delay time passes following OFF of an external device. Disable
the input OFF delay function or change the setting of the delay time.

Action
There is a problem with output wiring.
Check the wiring confirming that the output wiring is not disconnected or short-
circuited.
Check that Operating condition setting request flag (address: 2D07H) is off. If
Operating condition setting request flag (address: 2D07H) is on, turn it off and
check that Remote READY (RWr0.b11) is on.

Specify the relevant channel in "Write Value" of "Device Changeout Complete"
of "Command Execution of Slave Station".

Check that the operation mode matches that of the external output device,
and correct it if necessary. For details on the operation mode setting, refer to
the following.

Action
Please consult your local Mitsubishi representative.
Perform PLC verification on the network parameter to check those settings.
When they are not matched, perform reading and writing and match the
network parameter settings with those of the module and write the module
parameter of the slave station.
