Question about alarms

[sveseli]

PvaPy can process record on write using on write callback. Hence, if you wanted to do this using pvapy, you can (see https://epics.anl.gov/extensions/pvaPy/production/pvaccess.html#pvaserver). As far as I know, the underlying PV Database records are not doing any processing automatically at the moment.

I will start adding support for control and valueAlarm in PVRecord.
There is a method PVRecord::process that already has support for updating the timeStamp.
I will let it also implement control and valueAlarm if those fields exist at top level of record.

Hey, Sinisa, thank you for your answer! To be honest, I expected something like that, I mean, we need to implement the behaviour when a PV value reaches such limits. I think we can use PvaServer by now...

I was studying channel monitors that seem to be an option already available, too.

That would be awesome, Marty! Thank you. I'll follow the next updates, so...
