Dear Experts,

I know there have been many posts with questions and answers regarding the issue of Backup/Restore of WinCC Comfort Panels (TP700, TP900, etc).  I read most (almost all) of them.
I do know how to use ProSave and I do understand that the .BRF files are not editable and can be transferred to the same model of HMI Panel only. Finally, the .BRF file 

But I would like to know if there is any way to backup (and later restore) a PARTIAL backup from the Comfort panel containing only the WinCC RT (for example, V13 and later) and the non-editable Application that loads automatically during the HMI panel startup? That is without full OS and its settings.

Could the ProSave tool do that?  Or do I have to use any other program (TIA? or SAT?)
Or could this be done if a SIMATIC HMI memory card? (6AV2181-8XP00-0AX0)?

Please check and let me know at your earliest convenience.

Thanks and Best Regards,

Hi,

Have you seen this link:

Backup/Restore for Comfort Panels

I think partial backup is only possible for Recipes, user administration or Complete

Hello Wizard, thank you for the quick reply and a helpful link. The videos on that page confirmed what I have known already. 

So, you are saying that the PARTIAL backup/restore for RT and Application only is impossible, right?

If so, what would be the best course of actions to get rid of (remove) the "Secure Mode" which was accidentally enabled by the user?

Please consider the following scenario:

1. A user somehow sent the HMI into "Secure Mode" (maybe they clicked on the "secure mode" short cut which is placed on the Desktop of the TP900 Comfort HMI panel OS? ).

2. Nobody knows what the Secure Mode Password is. So, it is impossible to access the Control Panel, Taskbar or click on any Desktop icons. However, the main Application still can be started.

3. At this condition, I used ProSave to do a COMPLETE Backup of the HMI device and got a backup.BRF file.

4. Then, I used the "OS Update" function of ProSave to remove the Secure Mode. But the Application (all the screens and buttons that the user needed to use) is not there, of course.

5. How can I Restore (download) the Application (only!) to that HMI panel at this stage?
    (If I use ProSave to Restore my .BRF file, then the HMI panel would go back to "Secure Mode"!)

6. We don't have the original TIA project for this Comfort Panel device or even the Pack-and-Go package. Also, we don't have the .BRF file without the Secure Mode. 

Can you please advise WHAT can we do to let that HMI Panel run the Application in normal (not Secure) mode? Would it help to have a SIMATIC HMI memory card (6AV2181-8XP00-0AX0) installed in the System SD card slot (X50)?

Please let me know.

Thank you and Best Regards,
