Check the PVManager functions.
There’s something like   pv(‘name of PV’) for that.
In a PVManager formula, you can use (note the backquotes)
   =`name of PV` + 5

> 2nd Related question, as you all know, when you add a script to CSS it is executed (by default) on a trigger from a PV you add. How to have the same idea but without PVs? i.e., executing a script continuously without an external trigger so for example to update a widget's text value.
You can use “sim:ramp” as a PV that periodically triggers your script.
So it’s still a PV, but one that’s simulated inside CSS.
See online help for description on the simulated PV syntax.
