The AS Series CPU module still performs the data backup even if you click Cancel. You can turn off the
AS Series CPU module to stop the data backup; however, the backup file produced is not a complete
backup file, and you must delete the backup file from the memory card.
If you select Memory Card (PLC Side), the filename of the backup file is AUTOEXEC.dup, and the
backup file path is Root directory of the memory card\AS300\SysDup\AUTOEXEC.dup. If there is an
old backup file in the memory card, the Warning message appears. Click Replace, Archive, or Cancel in
the Warning message.
If the backed up data is protected by passwords, these passwords are also backed up.
