Folks,

There is something I don't quite understand about the ao and ai records with soft device support.

If I set DOL="1", then the init_record routine, either in the record (for ao), or in device support (for ai) sets prec->udf=0.  This is what I expect.  However, I find that after iocInit that STAT=UDF and SEVR=Invalid.  This is not what I expected.

The records never call checkAlarms in init_record, so the STAT and SEVR are not being reset to NO_ALARM.  Are the STAT and SEVR fields to to UDF and INVALID somewhere else in base before init_record is called?

If I set PINI=1 in my database, then the record will process once, and STAT and SEVR will be set to NO_ALARM.  But I don't understand why I have to do this, why does a soft record initialize with STAT=UDF aand SEVR=Invalid when its DOL is OK?

Is this the desired behavior, and is there a way to make the STAT and SEVR be NO_ALARM without having to set PINI=1?

Thanks,
Mark
