Error details
A restoration is executed while the CPU module
status (such as programs, parameters, and file
structure) of restoration destination is different
from the status at the time of backup.
• No SD memory card is inserted.
• Removal and insertion of the SD memory card
is being enabled by SM609 (Memory card
remove/insert enable flag).
• The SD memory card is being disabled by
SM606 (SD memory card forced disable
instruction).
• The SD memory card is write-protected.
The CPU module is locked.
The specified command cannot be executed
because the CPU module data
backup/restoration function is being executed.
The number of backup data stored in an SD
memory card exceeds the upper limit value.
Bit5 of SD910 is turned on while the set value of
SD1928 is out of the allowable range.
Upper limit value of the number of the backup
data cannot be changed because a backup data
folder already exists.
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.
The data cannot be backed up because a
program with a block password for which
"Execution Program Protection Setting" has
been enabled exists.
Execution of the MC protocol command has
failed because of the following error.
• Format error
• Data size error
• Data count error
• Unsupported command error
Execution of MC protocol command is disabled
in parameter.
The execution/error completion type setting of
the dedicated instruction is incorrect.
Corrective action
Check and correct the CPU module status to the
one at the time of backup and then execute the
restoration again. Change SD917 to all the target
data of backup and restoration, and then execute
the restoration again.
• Insert or re-insert the SD memory card, and then
execute the processing again.
• Disable the removal and insertion of the SD
memory card, and then execute the processing
again.
• Enable the SD memory card operation and then
execute the processing again.
• Cancel the write protection and then execute the
processing again.
When using the CPU module data
backup/restoration function, unlock the CPU
module and then execute the function.
After the CPU module data backup/restoration
function is completed, execute the command
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.
After check and correct the set value of SD1928,
turn on bit5 of SD910.
After deleting the backup data folder in the SD
memory card and turning off bit5 of SD910
temporarily, turn on bit5 of SD910 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, and execute the function again.
Clear "Execution Program Protection Setting" of
the block password and execute the function
again.
Check and correct the contents of the MC protocol
command mail.
Check and correct the parameter setting.
• Correct the execution/error completion type
setting in control data, and execute the
instruction again.
• If an error still exists even after taking the above
action, the possible cause is a hardware failure
of the module. Please consult your local
Mitsubishi representative.
