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
