Hi Amien,

One single mbbo record should do the job.
Configured quite like your rangeStr, but with PINI, DTYP and OUT from range.

Cheers,

I have a BOY "Choice Button" with its PV set to "$(dev):RangeStr"
My 'range' PV is between 1 and 8 with a corresponding ENUM string of 8 also.
The widget works fine in that it sets the 'range' on selecting the ENUM
but when I do
a write to the 'range' from elsewhere, the 'range' is set to the value
but my ENUM widget it not.
I then added the '$(dev):RangeENUM' record so that whenever a
'$(dev):range' is done, a FLNK updates my widget as well.
This works as I would want it to be I'm sure there is a better way (not
having 2 mbbo records ie).

   record(ao,         "$(dev):range")  {
      field(DTYP,   "asynInt32")
      field(PINI,   "YES")
      field(OUT,    "@asyn(int32 $(addr) 1.0) reason(2)")
      field(FLNK,   "$(dev):RangeENUM PP")
   }

      field(FVST, " 5  :   1 uA")

      field(SVST, " 7  :  10 nA")
      field(EIST, " 8  :   1 nA")
    }

   record(mbbo, "$(dev):RangeENUM") {
      field(DTYP, "Soft Channel")
      field(OMSL, "closed_loop")
      field(DOL,  "$(dev):range")
