His record is processing at 10Hz so it takes effect in 100 ms without FLNK.

SMOO does not update record when it changes, correct? Wouldn't you need to add a FLINK in the ao record to make this work?
record(ao,            "$(dev):sm")    {
      field(DESC,        "Smoothing")
      field(OUT,         "$(dev):rawval.SMOO")
      field(FLNK,       "$(dev):rawval")
   }

Field SMOO is not a link field.  You need to arrange for the sm record to write its value to rawvalue.SMOO.  To do that you need to change it from an ai to an ao record.

This should work:

   record(ao,            "$(dev):sm")    {
      field(DESC,        "Smoothing")
       field(OUT,         "$(dev):rawval.SMOO")
   }

Subject: SMOO expects constant

Hi here I have 2 of my database records:

################################################################
1)    record(ai,            "$(dev):sm")    {
2)       field(DESC,        "Smoothing")
3)    }
4)    record(ai,            "$(dev):rawval")        {
5)        field(SCAN,        ".1 second")
6)        field(DTYP,        "asynInt32")          #
7)        field(INP,         "@asyn(int32 $(addr) 100)")
8)        field(SMOO,        "$(dev):sm")
9)        field(FLNK,        "$(dev):coef")
      }

################################################################

This fails on

Can't set "bc1:rawval.SMOO" to "bc1:sm"
Error at or before ")" in file "db/newioc8.db" line 8

If I put a constant (0 - 1) in line(8) it works
