AUTO BACKUP SCREEN


AUTO BACKUP SCREEN

The Automatic Backup function performs the function of All backup in the FILE menu automatically at the following times:

  • The specified time (Up to 5 settings).

  • When the specified DI is turned on.

  • At controller startup. (An interval can be specified.)

There is a special area for Automatic Backup in the controller F-ROM (FRA:). You do not need an external device to use Automatic Backup, but a memory card can also be used.

The Automatic Backup function can manage many backup versions on one device. Even if you back up the wrong programs or settings, you can load the previously backed up version. The number of versions to keep can be set from 1 up to 99. (The default is 2.)

If a memory card is used as the backup device, it must be initialized for Automatic Backup. If the Memory Card is not initialized for Automatic Backup, the Automatic Backup function will not write to the Memory Card. There is no concern about accidentally writing to the wrong memory card. USB is not supported for Automatic Backup.

If the controller power is down during Automatic Backup, backup is performed at the next startup. If you cancel the backup, or if an error occurs in backup, the latest version of backup is recovered automatically. The backup device never has incomplete backup files.
