Error Error name Error details and cause
code
4C19H CPU module • The data restoration function was executed with backup files
data backup/ ($BKUP_CPU_INF.BSC and BKUP_CPU.BKD) not
restoration structured properly.
function error • Data (file(s)) is missing in the backup file
($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.
4C1AH CPU module • A folder with a value that matches the restoration target date
data backup/ folder setting value or number folder setting value does not
restoration exist in the SD memory card.
function error • 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.
4C1BH CPU module • The data restoration function was executed to the CPU
data backup/ module whose status (such as programs, parameters, and
restoration file structure) differs from that of when the data backup
function error function was executed.
4C1CH CPU module • An SD memory card is not inserted.
data backup/ • An SD memory card is disabled by SM606 (SD memory card
restoration forced disable instruction).
function error • An SD memory card is write-protected.
4C1EH CPU module • When an SFC program start mode is set to "Resume start",
data backup/ the status of the SFC program (such as step status and
restoration transition conditions) has been changed during execution of
function error the data backup function.
4C1FH CPU module • The specified command cannot be executed because the
data backup/ CPU module data backup/restoration function is being
restoration executed.
function error
4C20H CPU module • The data backup/restoration function was executed while
data backup/ the CPU module was in a state where this function could not
restoration be executed.
function error
4C21H CPU module • The number of backup data stored in an SD memory card
data backup/ exceeds the upper limit value.
restoration
function error
4C22H CPU module • Bit 5 of SD944 has been turned on while the set value of
data backup/ SD1353 is out of the allowable range.
restoration
function error
4C23H CPU module • Upper limit value of the number of the backup data cannot
data backup/ be changed because a CPU data folder has already been in
restoration an SD memory card.
function error
4C24H CPU module • The data cannot be backed up because more backup data
data backup/ than the upper limit value of the number of backup data
restoration exists in the SD memory card.
function error
4C40H File transfer • When files are specified by using wild card characters for the
function (FTP file transfer function instruction, the number of files matched
client) error exceeds the upper limit of the transferable number of files.
• When files are specified by using wild card characters for the
file transfer function instruction, no files are matched.
4C43H File transfer • The number of processing completed files for sending or
function (FTP acquiring FTP client file is mismatched with the total number
client) error of processing files.
Action
• The backup data may have been corrupted. Execute the
data restoration function using another backup data.
• 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.
• Match the CPU module status to the one at the time of
backup, and execute the function again.
• Set all data as the restoration target data, and execute the
automatic data restoration function.
• 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.
• Take measures so that the status of the SFC program does
not change during execution of the data backup function,
and execute the function again.
• Execute the command again after the data backup/
restoration processing ends.
• Deselect the "Access from External Device" checkbox in the
label setting window or delete labels with this item selected,
and initialize the memory which is written the global label
assignment information. Then, execute the data backup
function again.
• Initialize the memory where the global label assignment
information is written and execute the restoration function
again.
• Check the firmware version of the CPU module and execute
the automatic data restoration function again.
• Delete backup data in the SD memory card, and execute the
function again.
• Check and correct the settings of the upper limit value of the
number of backup data, and execute the function again.
• Check and correct the set value of SD1353, and turn on bit 5
of SD944.
• After deleting the CPU data folder in the SD memory card
and turning off bit 5 of SD944, turn on bit 5 of SD944 again.
• Delete the backup data exceeding the upper limit value, and
execute the function again.
• Check and correct the settings of the upper limit value of the
number of backup data, and execute the function again.
• Check and correct the wild card specification.
• Check if the specified folder path exists.
• Execute the function again.
