12.6 Backing up and restoring the CPU configuration
S7-1500R/H redundant system
System Manual, 01/2024, A5E41814787-AF
423
To start the backup restore, proceed as follows:
1. In the project, open the folder of the top CPU 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.
5. The "Load preview" dialog window sets out the key information on the restore process to be
run: For a restore, you must switch the S7-1500R/H redundant system to the STOP system
state.
6. In the "Action" column, select the "Overwrite" command from the drop-down menu.
7. Click "Download". The redundant system switches to the STOP system state. The backup is
transferred to the primary 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".
Reference
You can find more information on the various types of backup in the STEP 7 online help.
Emergency address (emergency IP)
If you cannot access the CPU via the IP address, you can set a temporary emergency IP
address for the CPU. To the more information on emergency address options, please refer to
the Communication (https://support.industry.siemens.com/cs/ww/de/view/59192925/en)
function manual.
Storage of multilingual project texts
Different categories of texts are created when you configure a CPU, for example
• Object names (names of blocks, modules, tags, etc.)
• Comments (for blocks, networks, watch tables, etc.)
• Messages and diagnostic texts
Texts are provided by the system, for example texts in the diagnostics buffer, or they are
created during configuration, for example messages.
Texts exist in the project in one language or, after a translation process, in multiple
languages. You can maintain project texts in all languages available to you in the project tree
(Languages & resources > Project texts). The texts created during configuration can be
downloaded to the CPU.
