A
4C11H CPU function
dedicated error
• An SD memory card is not inserted.
• An SD memory card is disabled by SM606 (SD memory
card forced disable instruction).
• Insert or re-insert an SD memory card, and execute the
function again.
• Enable the SD memory card operation, and execute the
function again.
4C12H CPU function
dedicated error
• Reading/writing of data from/to an SD memory card
completed with an error.
• Check that an SD memory card is inserted, and execute the
function again.
• Replace the SD memory card, and execute the function
again.
• The backup data may have been corrupted. Execute the
data restoration function using another backup data.
4C13H CPU function
dedicated error
• Reading/writing of data from/to the CPU built-in memory
completed with an error.
• The backup target files opened in the CPU built-in memory
are duplicated.
• Back up data in the CPU built-in memory, initialize the
memory, and write the data back to the original memory.
Then, execute the data backup/restoration function.
• The possible cause is a hardware failure of the restoration
target CPU module. Execute the data restoration function to
another CPU module.
• Execute the function again after a while.
4C14H CPU function
dedicated error
• The CPU module data backup/restoration function cannot
be executed because a file password is set to the data.
• Data was restored to the CPU module where the same data
with a file password has already been stored.
• Delete file passwords, and execute the CPU module data
backup/restoration function.
4C15H CPU function
dedicated error
• The function that cannot be executed simultaneously with
such as the file transfer function (FTP) is being executed.
• Execute the function again after a while.
4C17H CPU function
dedicated error
• The backed up CPU module and restoration target
destination CPU module models were different when
restoration was executed.
• Execute restoration again with the same CPU module
model as the backed up CPU module.
4C18H CPU function
dedicated error
• Data was restored while the operating status of the CPU
module is in RUN or PAUSE.
• Change the operating status of the CPU module to STOP,
and execute the function again.
4C19H CPU function
dedicated error
• The data restoration function was executed with backup
files ($BKUP_CPU_INF.BSC and BKUP_CPU.BKD) not
structured properly.
• Data (file(s)) is missing in the backup file
($BKUP_CPU_INF.BSC) in the backup data folder.
• The data restoration function was executed with a folder
where no backup files ($BKUP_CPU_INF.BSC,
BKUP_CPU.BKD, and BKUP_CPU_DEVLAB.BKD) are
stored.
• The backup data may have been corrupted. Execute the
data restoration function using another backup data.
4C1AH CPU function
dedicated error
• A value outside the allowable range was set to to the
operation mode.
• An out-of-range value was set for the CPU module auto
exchange function restoration target data setting (SD9351).
• A folder with a value that matches the restoration target
date folder setting value or number folder setting value does
not exist in the SD memory card.
• The restoration target data setting value is out of range.
• The restoration target date folder setting value or number
folder setting value is out of range.
• Check the operation mode setting value, and execute again.
• Review the CPU module auto exchange function restoration
target data setting value, and execute again.
• Check and correct the restoration target date folder setting
value or number folder setting value, and execute the
function again.
• Check and correct the restoration target data setting value,
and execute the function again.
4C1BH CPU function
dedicated error
• The data restoration function was executed to the CPU
module whose status (such as programs, parameters, and
file structure) differs from that of when the data backup
function was executed.
• Match the CPU module status to the one at the time of
backup, and execute the function again.
4C1CH CPU function
de
dicated error
• An SD memory card is not inserted.
• The SD memory card is disabled by SM606 (SD memory
card forced disable instruction).
• The SD memory card is write-protected.
• Insert or re-insert an SD memory card, and execute the
function again.
• Enable the SD memory card operation, and execute the
function again.
• Cancel the write protection, and execute the function again.
4C20H CPU function
dedicated error
• The data backup/restoration function was executed while
the CPU module is in a state where this function cannot be
executed.
• Initialize the CPU built-in memory, and execute the data
restoration function again.
