A
440BH Security function
error • Password authentication failed when access was required. • Set a correct password and perform password
authentication again 15 minutes later.
440CH Security function
error • Password authentication failed when access was required. • Set a correct password and perform password
authentication again 60 minutes later.
440DH
440EH Security function
error • The security function was activated and password
authentication cannot be performed.
• Set a correct password and perform password
authentication again after a certain period of time.
440FH Security function
error • An operation was performed to the firmware update
prohibited file with a file password set.
• Disable the file password setting.
4410H Security function
error • The file of the locked CPU module is accessed without the
security key authentication.
• 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.

4412H Security function
error • The security key cannot be registered to the CPU module
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.
• Hardware failure of the CPU module. Replace the CPU
module.
4413H Security function
error • Since the CPU module is locked and 32 engineering tools
are reading and writing programs simultaneously, another
engineering tool cannot read or write programs.
• Wait until the number of engineering tools which are reading
and writing programs decreases to 31 or less, and read or
write programs.
4414H Security function
error • The request cannot be executed because the CPU module
is locked.
• Do not execute the request because it cannot be executed
by the CPU module which is locked.
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 or battery-less option cassette
inserted in the CPU module.
• Check that an extended SRAM cassette or battery-less
option 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/
battery-less option 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/
battery-less option cassette).
• Clear the security key set to the file, and then execute the
online change function.
4800H iQ Sensor
Solution related
error • The specified command cannot be executed because the iQ
Sensor Solution data backup/restoration function is being
executed.
• Execute the command again after the processing of the data
backup/restoration function ends.
4801H iQ Sensor
Solution related
error • When the iQ Sensor Solution data backup/restoration is
requested, the target module does not exist.
• 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.
• 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.
4802H iQ Sensor
Solution related
error • The number of backup folders used by the iQ Sensor
Solution data backup/restoration function has reached to its
limit.
• 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.
