36.4 List of Error Codes
Error details and cause
• The request cannot be executed because an
error has been detected in the communications
between the CPU modules of the control system
and the standby system.
• The error was not cleared. (Error clear was
performed during execution of error clear.)
• The target module cannot handle the error clear.
• A file protected by a password has been opened
without unlocking the password.
• Read password authentication has failed when
required.
• The file password format is incorrect.
• Write password authentication has failed when
required.
• The file password format is incorrect.
• Both passwords for reading and for writing that
are set upon Create, Change, Delete, or Disable
do not match the previous ones.
• A file error was detected before or after
performing Create, Change, or Delete.
• Password authentication failed when access was
required.
• Password authentication failed when access was
required.
• Password authentication failed when access was
required.
• Password authentication failed when access was
required.
• Password authentication failed when access was
required.
• The security function was activated and
password authentication cannot be performed.
• An operation was performed to the firmware
update prohibited file with a file password set.
• The file of the locked CPU module is accessed
without the security key authentication.
• 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.
• Since the CPU module is locked and 32
engineering tools are reading and writing
programs simultaneously, another engineering
tool cannot read or write programs.
• The request cannot be executed because the
CPU module is locked.
Action
• Check if the tracking cables have been properly connected. If
the same error code is displayed again even after the
tracking cables are connected properly, the possible cause is
a hardware failure of the CPU module, redundant function
module, or tracking cable. Please consult your local
Mitsubishi representative.
• Execute again after a while.
If the same error code is displayed again, the possible cause is
a hardware failure of the target module. Please consult your
local Mitsubishi representative.
• Check the target module. (Check the module in which the
error occurred.)
• Enter a correct password and perform password
authentication.
• Set a correct read password and perform password
authentication.
• Access the file with the correct method.
• Set a correct write password and perform password
authentication.
• Access the file with the correct method.
• Set correct passwords for both reading and writing, and
perform password authentication.
• Initialize the drive including the target file by initializing the
memory.
• Write the target file to the programmable controller again,
and then register or cancel the file password.
• Set a correct password and perform password authentication
again.
• Set a correct password and perform password authentication
again 1 minute later.
• Set a correct password and perform password authentication
again 5 minutes later.
• 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.
