Process Variables
Most CSS tools support several types of process variables (PVs).
When simply using a PV name like
some_pv_name
this will refer to a default PV type which can be configured
in the PV preferences.
To select a specific PV type, use the PV name format
type://some_pv_name
Consult the syntax of each data source for details.
Preferences
The default PV type can be selected via the menu
CSS/Preferences/Applications/Configuration/Process Variables.
