iQ Sensor
Solution related
error
Data cannot be communicated with external
devices when the iQ Sensor Solution function
(data backup/restoration) is executed.
• Check the external device operation.
• Check the status of devices (such as cables,
hubs, and routers) on the line to the external
devices.
• The line may be congested. Resend data after a
while.

iQ Sensor
Solution related
error
• When the restoration of the iQ Sensor Solution
function (data backup/restoration) is
performed, the backup source device
supporting iQ Sensor Solution and the
restoration target device supporting iQ Sensor
Solution do not match.
• The CPU module is not compatible with the
CC-Link-AnyWireASLINK bridge module.
• Check the manufacturers, models, and versions
of the specified backup source device
supporting iQ Sensor Solution and the
restoration target device supporting iQ Sensor
Solution.
• Replace the CPU module with a CPU module
that is compatible with the CC-Link-
AnyWireASLINK bridge module.

iQ Sensor
Solution related
error
The function was executed to the module which
does not support the iQ Sensor Solution function
(data backup/restoration).
• Replace the module to the one which supports
the iQ Sensor Solution function (data
backup/restoration).
• Execute the function to the module which
supports the iQ Sensor Solution function (data
backup/restoration).

error
The function was executed to the CC-Link
module whose operating status has been
switched from the standby master station to the
master station.
Turn off and on the power supply for the master
station and the standby master station, and
execute the function again.

iQ Sensor
Solution related
error
The function was executed to the CC-Link
module for which the "Read the model name of
slave station" checkbox is not checked in
parameter.
Check the "Read the model name of slave station"
checkbox for the auto detect setting in parameter,
and execute the function again.

iQ Sensor
Solution related
error
The specified command cannot be executed
because the iQ Sensor Solution function
(automatic detection of connected device) is
being executed.
Execute the command again after the iQ Sensor
Solution function (automatic detection of
connected device) ends.

H
iQ Sensor
Solution related
error
The specified command cannot be executed
because the iQ Sensor Solution function
(communication setting reflection) is being
executed.

iQ Sensor
Solution related
error
• The specified command cannot be executed
because the iQ Sensor Solution function
(monitoring) is being executed.
• The specified command cannot be executed
because the iQ Sensor Solution function
(sensor parameter read/write) is being
executed.
• Execute the command again after a while.
• Execute the command again after the iQ Sensor
Solution function (sensor parameter read/write)
ends.

Other error
After the values in "Device" of "PLC Parameter"
of the CPU module, where the simple PLC
communication function had been set, were
changed, the parameters were written to the
CPU module from the "Write to PLC" window.
Power off and on the CPU module. Or reset the
CPU module.
LCPU
4901
H
Other error
The file register used for the simple PLC
communication function became out of range
due to the block number change of the file
register.
Correct the device number of the file register. And
power off and on the CPU module or reset the
module.
LCPU
4902
H
Other error
The communication was stopped because an
error occurred at the other setting No., for which
the same destination device of the
corresponding setting No. had been set.
Remove the error cause. LCPU
4903
H
Other error
The communication was stopped because a stop
error occurred in the CPU module where the
simple PLC communication function had been
set.
Power off and on the CPU module. Or reset the
CPU module.
LCPU

H
Other error
The specified command cannot be executed
because a file or folder is being deleted using a
display unit.
After the delete processing is completed, execute
the command again.
