Re: [PV Access] Decimation Channel filter equivalent for PV Access?

["Johnson, Andrew N. via Tech-talk" <tech-talk at aps.anl.gov>]

Was that a typo in your email or were you really asking pvmonitor for n:1 and not n:2?

Hi Michael,

Thanks for your reply.

I was suspicious, because I had the feeling I used it in the past... Can you maybe then give me a clue why I can't make it work in a simple example?

This is my db file:
record(calc, "Test:counter") {
   field(INPA, " Test:counter")
   field(CALC, "A+1")
   field(SCAN, "1 second")
}

And I run it using softIocPVA.

If I do
camonitor 'Test:counter.{"dec":{"n":2}}'
I get every second update, while if I do
pvmonitor 'Test:counter.{"dec":{"n":2}}'
I get nothing. Funny enough, if I do
pvmonitor 'Test:counter.{"dec":{"n":1}}'
then I get every update...

I am using base 7.0.4, but I also tested 7.0.3.1, which is the one I used in the past when testing the filters.

Cheers,
Juan

Hi all,



I would like to know if there is anything equivalent to the CA decimation filter in PV access.

https://epics.anl.gov/base/R7-0/4-docs/filters.html#Decimation-Filter-dec

   These filters are implemented at the database level, and so work both with CA and PVA
   (via. the RSRV and QSRV server implementations).
