A
4C19H CPU module
data backup/
restoration
function 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 module
data backup/
restoration
function error
• 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 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 module
data backup/
restoration
function 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.
• Set all data as the restoration target data, and execute the
automatic data restoration function.
4C1CH CPU module
data backup/
restoration
function error
• An SD memory card is not inserted.
• An SD memory card is disabled by SM606 (SD memory card
forced disable instruction).
• An 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.
4C1EH CPU module
data backup/
restoration
function error
• When an SFC program start mode is set to "Resume start",
the status of the SFC program (such as step status and
transition conditions) has been changed during execution of
the data backup function.
• 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.
4C1FH CPU module
data backup/
restoration
function error
• The specified command cannot be executed because the
CPU module data backup/restoration function is being
executed.
• Execute the command again after the data backup/
restoration processing ends.
4C20H CPU module
data backup/
restoration
function error
• The data backup/restoration function was executed while
the CPU module was in a state where this function could not
be executed.
• 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.
4C21H CPU module
data backup/
restoration
function error
• The number of backup data stored in an SD memory card
exceeds the upper limit value.
• 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.
4C22H CPU module
data backup/
restoration
function error
• Bit 5 of SD944 has been turned on while the set value of
SD1353 is out of the allowable range.
• Check and correct the set value of SD1353, and turn on bit 5
of SD944.
4C23H CPU module
data backup/
restoration
function error
• Upper limit value of the number of the backup data cannot
be changed because a CPU data folder has already been in
an SD memory card.
• 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.
4
C24H CPU module
data backup/
restoration
function error
• The data cannot be backed up because more backup data
than the upper limit value of the number of backup data
exists in the SD memory card.
• 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.
4C40H File transfer
function (FTP
client) error
• When files are specified by using wild card characters for the
file transfer function instruction, the number of files matched
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.
• Check and correct the wild card specification.
• Check if the specified folder path exists.
4C43H File transfer
function (FTP
client) error
• The number of processing completed files for sending or
acquiring FTP client file is mismatched with the total number
of processing files.
• Execute the function again.
