Downgrade a project from V13 ->V11

Hello people. 

Do anybody know if it's possible to downgrade a WinCC project from V13  -> V11 ? 

Best Regards!

Hello,

do you mean that you can open the project in TIA V11 ? Then this is not possible.
You can change the Version of the HMI in V13, but the project version you can't change.

Regards

Christoph

Christoph,

Do you have a link to the instructions on how to convert the terminal back to V11?

Hello BDunc

• Open the hardware configuration.
• Right-click on the panel or runtime (on the graphicin the grey part, not on the grey part itself).
• Select "Change device / version" in the context menu.
• Select your panel / runtime on the right and select the version you want in the drop down list under the "New device" (in the middle).
• In the list "Comatibility information" (on the bottom) you can see what changes will happen ad which elements will disappear.
  (Maybe it's better to delete objects that are not availiable in V11 beforehand (like pop-ups and slide-ins)?)
• Click "OK".

Like someone said before - you can't open this project in a V11 TIA Portal engineering system, but it will work with a V11 runtime. If you put it on a panel the software will downgrade itself automatically and upgrade itself again if a project with a newer version is loaded onto it later.
