Hi Tim, Strictly speaking PVs don’t have fields, records have fields. PVs are basically record fields. So any place where you assign a PV to an SNL variable you can use an field name like .HIHI. Here is an example where the .PROC field is used.

On Behalf Of Madden, Timothy J. via Tech-talk Tech Talk: Is there a way to set or get specific fields of a PV from a SNL program? Example, say we want to pvPut the HIHI field of a PV. I see ways to get/put VAL by assign and pvGet()/pvPut(). But I don't see a way to get other fields of the PV. Tim Madden APS |
