Experimental Physics and
Industrial Control System

I was looking at PV structures and how to utilize them properly, and I’ve discovered that there are two ways to create them. The first is using  QSRV through .db files, and the other is using PVXS through C++ files. I was wondering what the differences between the two were in terms of functionality. From my rather limited experience with epics, the difference between the two seems like QSRV is limited to built-in epics records, so wouldn’t be able to store a matrix of some kind. However, I’m not sure if that’s actually the case. As such, I was hoping someone with more experience with PV structures could help explain the difference to me.

 

Sincerely,
