12.7 Backing up and restoring the CPU configuration
Example: Restoring a backup of an online device
If you have saved the CPU data beforehand, you can transfer the backup back to the device.
The saved backup is then restored to the CPU.
The S7-1500 automation system is in RUN mode. Before the restoration, the CPU goes into
STOP mode.
To start the backup restore, proceed as follows:
1. Open the CPU's folder in the project navigator. The lower-level objects are displayed.
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.
5. The "Load preview" dialog window sets out the key information on the restore process to be
run. For a restoration you have to switch the CPU to the STOP mode.
6. In the "Action" column, select the "Overwrite" command from the drop-down menu.
7. Click "Download". The CPU changes to STOP mode. The backup is transferred to the CPU and
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 (no
action, start modules).
8. Click "Finish".
