Ø  The mbbi record in the couple of versions of base that Ive checked (3.15.5 and 3.15.7) don’t seem to use the MASK field.

 

I believe that is the responsibility of the device support.  asyn device support handles the mask.

This is one of those things that seems impossible to have been wrong for so long that it makes me wonder if I’m misinterpreting what I’m reading.

The mbbi record in the couple of versions of base that Ive checked (3.15.5 and 3.15.7) don’t seem to use the MASK field.

 

wenorum@xildev5 223> pwd

/eda/epics/R3.15.7/base/src/std/rec

wenorum@xildev5 224> grep -n mask mbbiRecord.c

140:    if (prec->mask == 0 && prec->nobt <= 32)

141:        prec->mask = ((epicsUInt64) 1u << prec->nobt) - 1;
