aSub Question

["Szalata, Zenon M." <zms@slac.stanford.edu>]

I have a waveform and an aSub records.  I want to transfer data from the waveform to the aSub record and I am having difficulties with that.

Here is my (simplified) waveform record:

record( waveform, "$(P):WF:REQUEST"){
  field( DESC, "struct for request")
  field( FTVL, "CHAR")
  field( NELM, "132")
  field( FLNK, "$(P):AS:REQUEST")
}

and here is my aSub record:

record( aSub, "$(P):AS:REQUEST"){
  field( DESC, "struct for request")
  field( INAM, "asInitialize")
  field( SNAM, "asRequest")
#  field( INPA, "(P):WF:REQUEST")
  field( FTA,  "CHAR")
  field( NOA,  "132")
  field( FTVA, "UCHAR")
  field( NOVA, "132")
}

When I process the waveform record, the asRequest routine gets called when the INPA field is commented out.  However, when I uncomment the INPA field, asRequest routine no longer gets called when the waveform record is processed.  Looking at the TIME field in the aSub record I can tell that the records is getting processed each time I process the waveform record, regardless if the INPA field is commented out or not.

Is it not allowed to transfer array of bytes from one record to another?
Is there a way to make that kind of data transfer?

Thanks in advance,
Zen
