PI Vision error: "This display is not available"

Discussion created by C_Haas on May 19, 2020

Hello together,


I have edited the default TimeRange of a display in PI Vision, that I already created a few months ago. 

After safing the changes I got the error in the Screenshot.

The display is still available in the Display Overview (PMO_Machine_Overview). 

If I try to open it from here or with a direct link to the display number I get the same error. 


In my PI Vision Display Utility, the Display is available as well. 


What can I do to regain the display and prevent such errors in the future?


Thank you in advance and best regards
