What is wrong:

FLNK does not pass any data. You need an OUT link to pass data. ai does

not have an OUT link. You need ao to do that. ao does not have an INP

link. Use DOL the link. To read the DOL you must set OMSL to

closed_loop. Make all the OUT links PP to process the offset record.

record(ao,           "$(dev):calcoffset")   {
       field(DTYP,   "Soft Channel")
       field(OMSL,   "closed_loop")
       field(DOL,    "$(dev):rawval")
       field(OUT,    "$(dev):offset PP")
  }
record(ai,           "$(dev):offset")       {
       field(DTYP,   "Soft Channel")
  }
record(ao,           "$(dev):zeroOffset")   {
       field(OUT,    "$(dev):offset PP")
       field(VAL,    "0")
  }

Hi

I have 3 records like this:

#############################################
record(ai,           "$(dev):calcoffset")   {
        field(DTYP,   "Soft Channel")
        field(INP,    "$(dev):rawval")
        field(FLNK,   "$(dev):offset PP")
   }
record(ai,           "$(dev):offset")       {
        field(DTYP,   "Soft Channel")
   }
record(ao,           "$(dev):zeroOffset")   {
        field(OUT,    "$(dev):offset")
        field(VAL,    "0")
   }
##############################################
All I want to do is to get a value from my Asyn INP (input) called
$(dev):rawval and assign the value to $(dev):offset.
Also I use $(dev):zeroOffset to set this to 0.

But somehow when I do a PUT to $(dev):calcoffset, my #(dev):offset is
not set to this INP value.
What I'm I doing wrong

Thanks
