code
440BH Security function • Password authentication failed when access was required.
error
440CH Security function • Password authentication failed when access was required.
error
440DH
440EH Security function • The security function was activated and password
error authentication cannot be performed.
440FH Security function • An operation was performed to the firmware update
error prohibited file with a file password set.
4410H Security function • The file of the locked CPU module is accessed without the
error security key authentication.
4412H Security function • The security key cannot be registered to the CPU module
error due to the failure of the internal memory where the security
key is registered. Or, the security key of the CPU module
cannot be deleted.
4413H Security function • Since the CPU module is locked and 32 engineering tools
error are reading and writing programs simultaneously, another
engineering tool cannot read or write programs.
4414H Security function • The request cannot be executed because the CPU module
error is locked.
4415H Security function • The request cannot be executed because the CPU module
error is not locked.
4416H Security function • The request cannot be executed because the CPU module
error lock or unlock processing is being performed.
4417H Security function • An attempt was made to write or delete the security key with
error no extended SRAM cassette or battery-less option cassette
inserted in the CPU module.
4418H Security function • The security key cannot be changed or deleted because any
error locked program exists in the CPU module.
4422H Security function • The access target CPU module does not support the
error security key information stored in the engineering tool.
4424H Security function • The security key set to the file written by executing the file
error batch online change function does not match the one
registered to the CPU module (or extended SRAM cassette/
battery-less option cassette).
4425H Security function • The file with a security key was written by executing the
error batch file online change function, but no security key is
registered to the CPU module (or extended SRAM cassette/
battery-less option cassette).
4800H iQ Sensor • The specified command cannot be executed because the iQ
Solution related Sensor Solution data backup/restoration function is being
error executed.
4801H iQ Sensor • When the iQ Sensor Solution data backup/restoration is
Solution related requested, the target module does not exist.
error • When the iQ Sensor Solution data restoration is requested,
the specified backup folder does not exist.
• The value in the special register (SD) related to the iQ
Sensor Solution data backup/restoration is out of range.
4802H iQ Sensor • The number of backup folders used by the iQ Sensor
Solution related Solution data backup/restoration function has reached to its
error limit.
Action
• Set a correct password and perform password
authentication again 15 minutes later.
• Set a correct password and perform password
authentication again 60 minutes later.
• Set a correct password and perform password
authentication again after a certain period of time.
• Disable the file password setting.
• Register the security key which locks the CPU module to the
engineering tool.
• When the project is opened, lock the project with the security
key which locks the CPU module.
• When the CPU module is locked, the access control target
file cannot be accessed using the following functions or
external devices.
 FTP server function
 SLMP/MC protocol
 GOT
 EZSocket
• Hardware failure of the CPU module. Replace the CPU
module.
• Wait until the number of engineering tools which are reading
and writing programs decreases to 31 or less, and read or
write programs.
• Do not execute the request because it cannot be executed
by the CPU module which is locked.
• Do not execute the request because it cannot be executed
by the CPU module which is not locked.
• Execute the request again after the lock or unlock
processing ends.
• Check that an extended SRAM cassette or battery-less
option cassette is correctly inserted, and then perform the
operation again.
• Unlock all the programs in the CPU module.
• Change the security key information version of the
engineering tool in accordance with the version supported
by the target CPU module.
• Set the same security key registered to the CPU module to
the file, and then execute the file batch online change
function.
• Clear the security key set to the file, and then execute the
online change function.
• Execute the command again after the processing of the data
backup/restoration function ends.
• Check and correct the value in the special register (SD), and
execute the function again.
• Check that the backup data created by the MELSEC iQ-R
series module is specified.
• Delete an existing backup folder(s), and execute the function
again.
• Set "Automatic specification (Folder deletion supported)" in
the special register for setting a backup target folder
number.
