36 ERROR CODES
36.4 List of Error Codes
619
36
4415H Security function error • The request cannot be executed because the
CPU module is not locked.
• Do not execute the request because it cannot be executed
by the CPU module which is not locked.
4416H Security function error • The request cannot be executed because the
CPU module lock or unlock processing is being
performed.
• Execute the request again after the lock or unlock processing
ends.
4417H Security function error • An attempt was made to write or delete the
security key with no extended SRAM cassette
inserted in the CPU module.
• Check that an extended SRAM cassette is correctly inserted,
and then perform the operation again.
4418H Security function error • The security key cannot be changed or deleted
because any locked program exists in the CPU
module.
• Unlock all the programs in the CPU module.
4422H Security function error • The access target CPU module does not support
the security key information stored in the
engineering tool.
• Change the security key information version of the
engineering tool in accordance with the version supported by
the target CPU module.
4424H Security function error • The security key set to the file written by
executing the file batch online change function
does not match the one registered to the CPU
module (or extended SRAM cassette).
• Set the same security key registered to the CPU module to
the file, and then execute the file batch online change
function.
4425H Security function error • The file with a security key was written by
executing the batch file online change function,
but no security key is registered to the CPU
module (or extended SRAM cassette).
• Clear the security key set to the file, and then execute the
online change function.
4809H iQ Sensor Solution related
error
• The data backup/restoration function of iQ
Sensor Solution was executed to the module
which does not support the function.
• Replace the module with the one which supports the
function.
• Execute the function to the module which supports the
function.
480AH iQ Sensor Solution related
error
The function was executed to the CC-Link module
whose operation had been switched from the
standby master station to master station.
After powering off and on the master station and standby
master station, execute the function again.
480BH iQ Sensor Solution related
error
The function was executed for the CC-Link module
to which "Read Model Name of Device Station" is
not set in the setting of the automatic detection
function of connected devices.
Select "Read Model Name of Device Station" in the setting of
the automatic detection function of connected devices, and
execute the function again.
480CH iQ Sensor Solution related
error
• The specified command cannot be executed
because the automatic detection of connected
device function of iQ Sensor Solution is being
executed.
• Execute the command again after the automatic detection
processing ends.
480DH iQ Sensor Solution related
error
• The specified command cannot be executed
because the communication setting reflection
function of iQ Sensor Solution is being executed.
• A communication timeout occurred in a
command of a device supporting iQ Sensor
Solution.
• Execute the command again after the communication setting
reflection processing ends.
• Check and correct the communication time check setting
value using the engineering tool.
480EH iQ Sensor Solution related
error
• The specified command cannot be executed
because the monitor function of iQ Sensor
Solution is being executed.
• The specified command cannot be executed
because the sensor parameter read/write
function of iQ Sensor Solution is being executed.
• A communication timeout occurred in a
command of a device supporting iQ Sensor
Solution.
• Execute the function again after a while.
• Execute the command again after the sensor parameter
read/write processing ends.
• Check and correct the communication time check setting
value using the engineering tool.
4812H iQ Sensor Solution related
error
• The functions that cannot be executed
simultaneously with the data backup/restoration
function of iQ Sensor Solution, such as the file
transfer function (FTP server/client), are being
executed.
• Execute the function again after a while.
4902H Any other error • The communications have stopped because in
the simple CPU communication function, an error
occurred in another simple CPU communication
setting No. for which the same communication
destination is specified.
• Eliminate the error cause of the simple CPU communication
setting No. with an error.
