Let me assume PVa and PVb : if PVa=1 and PVb=1 then the visibility of the circle is invisible otherwise is visible. I open the circle properties window and have no idea how to process two PV names in Visibility PV blank. https://ics-web.sns.ornl.gov/edm/eum.html#idp216560 To use logic to make a widget visible based on the values of two or more PVs, you will need to use a CALC _expression_ in the visibility PV field of the widget. The screenshot below uses two LOC\ PVs in the calculation, you can replace these with real PVs. CALC\{A&&B}(LOC\PVa,LOC\PVb) ---- -> If A is true and B is true then CALC is true. 
As Zelazny replied earlier, you need to create a group for the widget you want to use visibility on. The group properties provide the attributes for visibility.2) how to control a text update widget visible or invisible according to PV. however, there is no Visibility PV blank to fill in in Text update properties window.
