Hi,

TMTOWTDI.  One way is to add SEVRCOMMAND's to ALH.  For example, here I set and reset an annunciator when there is a particular fault at beamline 13 (our most troublesome beamline...).  Snippet from an ALH config file (look at the ALH manual to understand the syntax):

CHANNEL MPS:BL13 BL13:Priority2Interlock     --A--
$SEVRCOMMAND UP_MAJOR      [ ${ALHMODE} = "st" ] && caput -w 5 MPS:Annunciator.B2 1 > /dev/null
$SEVRCOMMAND DOWN_NO_ALARM [ ${ALHMODE} = "st" ] && caput -w 5 MPS:Annunciator.B2 0 > /dev/null
