Since today, the 'connectivity' tab in the element properties pop-up window is not visible anymore for any element on my system, whereas it used to be there.
Any ideas on why this happened and how to get the tab to appear again? I can still access DCF information of my elements via the general parameters and via GQI, and all DCF connections that I configured earlier still seem to be there...
Can you check if the element is stopped?
Connections are stored in tables in the General Parameters page of every element.
You can't view data when the element is stopped, so that could explain why the connection tab is not visible.
