Trend not appear from a particular application when it drag and drop to existing trend display.
This is upgraded system from 5.1 Rev E to SV 18.104.22.168.
We are facing an issue with trend display in 800xA 22.214.171.124 System. We have a serial application and if we drag and drop the signal on any other application trend it does not show any trend and status shows red.
The trend is configured for Analogue function block for .in value.
When we drag and drop the signal on trend display the object shows as function, not function block. When we change it as function block and value .in it starts work.
For other applications it works fine.
what could be the reason.
Could you share some snaps.showing tree
Trend fetches data from the aspect object having log configuration.
Always drag-drop object having log configuration. If it's composite object having log configuration for child objects and trying to drag drop parent object to trend display will never works.
