Error during HMI Start in WebIQ HMI

[Matthias_Diez]

Hello,

when I press the start button in the remotemanger of my first loaded HMI in the WebIQ App, I get an error in like the picture below shown.

Error during HMI Start in App

I using the app which I got from Rexroth 2.7 and the latest designer from the webside from Smart HMI to create the first Control_plus_HMI.

May the underscores are the problem?

Thanks for answer in advance, Matthias

Hello,
the underscores are definitely not a problem, these are valid characters for filenames.
I suspect you used a newer version of the WebIQ Designer, e.g. V2.8.2 and then tried to start the project on the older WebIQ Server App V2.7. That leads to the error!
The WebIQ Server App (Runtime System) can only update an older version to the new version, but not the other way around.
I hope this information helps.
Best wishes
