Version compatibility inquiry

SMT_SOL · Post by **SMT_SOL** » Tue Jun 02, 2020 7:32 am

I am currently using WINCCOA version 3.12.

I understand that it is possible to connect to 3.16 DP from 3.12 client.

I'm curious about the compatibility in the UI part.
Based on panel
Can I run a project that is going back to 3.16 in 3.12?
Conversely, can I run version 3.12 as version 3.16?

In a WinCC OA system the server and the UI clients must have the same version.
Using different versions in one system is not supported.

A panel which was created/modified with 3.16 cannot be used in 3.12.
An upward compatibility of panels is given but not downwards.
