Example: Backup from online device
The following example shows how to carry out a complete backup of the current device state
of the CPU in STEP 7. The S7-1500 automation system is in RUN mode. Before the backup, the
CPU goes into STOP mode.
To start the backup, proceed as follows:
1. Right-click to select the CPU in the project tree.
2. Select the "Backup from online device" command from the shortcut menu.
The "Upload preview" dialog window sets out the key information on the backup process to
be run. For a backup you have to switch the CPU to the STOP mode.
3. In the "Action" column, select the "Stop module" command from the drop-down menu.
4. Click "Upload from device". The CPU changes to STOP mode. The backup of the CPU data
starts. The backup is saved in the project tree in the folder of the CPU under "Online
backups".
