36.4 List of Error Codes
Error details and cause
• The automatic backup setting by specification of
day and time is turned on while the setting value
(automatic backup date and time) are out of
range.
• The automatic backup setting by specification of
time and day of the week is turned on while the
setting value (automatic backup time and day of
the week) are out of range.
• The model of the restoration target CPU module
differs from the model of the backup source CPU
module.
• Data was restored while the operating status of
the CPU module is in RUN or PAUSE.
• 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.
• 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.
• 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.
• An SD memory card is not inserted.
• The SD memory card is disabled by SM606 (SD
memory card forced disable instruction).
• An SD memory card is write-protected.
• The status of the SFC program (such as step
status and transition conditions) was changed
during execution of the data backup function.
• The specified command cannot be executed
because the CPU module data backup/
restoration function is being executed.
• The data backup/restoration function was
executed while the CPU module was in a state
where this function could not be executed.
• The number of backup data stored in an SD
memory card exceeds the upper limit value.
• Bit 5 of SD944 has been turned on while the set
value of SD1353 is out of the allowable range.
• 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.
Action
• Review the setting value (automatic backup date and time)
and turn on the automatic backup setting by specification of
day and time.
• Review the setting value (automatic backup time and day of
the week) and turn on the automatic backup setting by
specification of time and day of the week.
• Execute the data restoration function to the CPU module
whose model is the same as that of the backup source CPU
module.
• Change the operating status of the CPU module to STOP,
and execute the function again.
• 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.
• Disable the automatic restoration function with the SD CARD
OFF button when not using it. Then, 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.
