With OPI Probe CSS context menu, CSS user can pass PV names to an OPI so that their PV values can be displayed in an OPI.
A probe OPI is same as an ordinary OPI, except that you need to set the "PV Name" property of a PV widget to:
$(probe_pv)
if the probe OPI only work for one PV;
$(probe_pv_index)
if the probe OPI should work for multiple PVs. index
is the index of the PVs that are passed in. For example, the widget with $(probe_pv_0)
will have
the first PV name passed in, $(probe_pv_1) will have the second PV name passed in, ...
The path of the probe OPI can be set in BOY preference page with the item Probe OPI
.
If no probe OPI is set in BOY preference, a built-in probe OPI will be used.
