Experimental Physics and Industrial Control System

Hello Hugo,
Thanks for the suggestion, I will have a look at PCASpy.
I was hoping that for such a trivial task I could directly inject PV values into CSS. I’m afraid that introducing EPICS in between may harm performance,
or not? Potentially I can be monitoring hundreds of PVs.
Sorry, if I’m talking nonsense, I’m a complete newbie in this domain. Are there any good reference manuals on CSS (for developers) besides the
CSS book, built-in help and GitHub Wiki?

Subject: Re: Custom SQL data source for CSS
Hello,
I need to connect to RDB and expose this data as PV. As far as I can tell there is no ready-made plugin in CSS that allows this.
Unfortunately, I didn’t manage to find any documentation on how to write my own data source plugins. I would be very grateful for any hints.
Is it mandatory to implement it in Java? Can I connect to RDB from _javascript_ and then put values into a new PV every second? And then display this PV in Boy.
Can I run this script in a separate thread and update PV from there?
Thanks in advance
