Correction
Insert an SD Memory Card.
Replace the SD Memory Card with an
SD or SDHC card.
Format the SD Memory Card with the
Sysmac Studio and then place the
backup files on it.
Place the backup files in the specified
folder on the SD Memory Card.
Create the backup files again.
Replace the CPU Unit with a CPU
Unit that has a unit version that is the
same as or newer than the unit ver-
sion of the CPU Unit that was used to
create the backup files. Or, specify
backup files with the correct unit ver-
sion for the CPU Unit.
Replace the CPU Unit with a CPU
Unit that has the same model as the
CPU Unit that was used to create the
backup files. Or, specify backup files
with the correct model for the CPU
Unit.
If there are no backup files or no
restore command file in the specified
folder on the SD Memory Card, place
the files in the folder again.
If you use the restore function, select
the Do not use Option for the Write
protection at startup setting of the
CPU Unit.
Make sure that the required files are
set to "Yes" in the restore command
file.
Wait for the backup operation to end
and then perform the restore opera-
tion again.
Wait for the synchronization, online
editing, or the Clear All Memory oper-
ation to end and then perform the
restore operation again.
Check the cable connections. Go
offline and then go back online and
execute the backup again.
Perform the same corrective mea-
sures as for when the format of the
SD Memory Card is not correct or the
SD Memory Card is damaged.
