To restore a backup, follow these steps:
1. Open the CPU in the project tree to display the lower-level objects.
2. Select the backup you want to restore from the "Online backups" folder.
3. From the "Online" menu, select the "Download to device" command.
– If you had previously established an online connection (Page 1313), 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 interface from which you want to
establish the online connection to the CPU.
4. Check the alarms in the "Load preview" dialog, and select the actions in the "Action"
column, if necessary.
5. Click the "Load" button (The "Load" button is selectable as soon as downloading is
possible.)
6. STEP 7 restores the backup to the CPU. From the "Load results" dialog, you can check
whether or not the loading operation was successful and take any further action that
might be necessary.
7. After reviewing the "Load results" dialog, click the "Finish" button.
If prompted, enter the password for full access to the CPU and confirm that the CPU can
enter "STOP" mode.
STEP 7 restores the contents of the backup to the CPU and restarts the CPU.
Note
Note that you can also restore a CPU backup from the
Web server Online backup standard
(Page 1035).
