Hi,

I was wondering if there is a way to fill with some initial values a waveform record in a db file,

I.e. something like

 

record (waveform,mywave){

  …

  field(VAL,”X Y Z”)

}


Yes, if you are using a recent EPICS 7 then you can initialize it using an array constant link like this:

record(waveform, wf100:i16) {
  field(FTVL, "SHORT")
  field(NELM, "100")
  field(INP, [1, 2, 3, 4, 5])
}

I forget exactly which version you need to be on (maybe 7.0.2), it doesn't have to be the version that just came out though.
