Restoring the software and hardware configuration of a device

If you have backed up the configuration of a device at an earlier point in time, you can transfer the backup back to the device. The saved configuration is then restored on the device.

Requirement

You must have previously configure the device and stored a backup of the device in the project.

Procedure

To restore older software and hardware state on a device, follow these steps:

  1. Open up the folder of the device in the project tree to display the lower-level objects.

  2. Open the "Online backups" folder.

  3. Select the backup you want to restore.

  4. In the "Online" menu, select the "Download to device" command.

    • If you had previously established an online connection, the "Load preview" dialog opens. This dialog displays alarms and recommends actions needed for the loading operation.

    • If you had not previously established an online connection, the "Extended download to device" dialog opens, and you must first select the interfaces via which you want to establish the online connection to the device.

  5. Check the alarms in the "Load preview" dialog, and select the actions in the "Action" column, if necessary.

    Note

    Performing the proposed actions during operation of the plant can cause serious damage to property or injury to persons if there are functional disturbances or program errors.

  6. As soon as downloading becomes possible, the "Load" button is enabled.

  7. Click the "Load" button.

    The backup is transferred to the device and device is restored. The "Load results" dialog then opens. In this dialog, you can check whether or not the loading operation was successful and take any further action that may be necessary.

  8. Click the "Finish" button.
