## Backing Up and Restoring IP Address Settings

The IP address setting of the External Device can be backed up to the Display. On the Hardware Configuration screen, you can edit the backed up IP address setting or restore the IP address to the External Device.

### Backing Up IP Address Settings

Touch [IP Address settings for NX Series] on the Hardware Configuration screen.

When [Backup] is touched on the displayed screen, the IP address setting of the External Device is backed up. The backed up IP address setting is displayed on the Hardware Configuration screen.

### Restoring IP Address Settings

Touch [IP Address settings for NX Series] on the Hardware Configuration screen.

When [Restore] is touched on the displayed screen, the IP address setting of the External Device is restored.

NOTE

- Backing up and restoring the IP address setting can be performed for the External Device of the same system configuration. The backed up IP address setting cannot be restored to an External Device of a different system configuration.
- Backing up and restoring the IP address setting is unique for each Ethernet Card. The backed up IP address setting cannot be restored to an External Device which is connected to another Ethernet Card.
- When the backed up setting is not displayed on the Hardware Configuration screen, touching [Restore] will not work.
- When using multiple chains to connect multiple External Device to one Ethernet Card, backing up and restoring IP address settings is not possible.
- You can also back up and restore IP address settings using the [Azbil] operation in a script.
