Get
Unity Gain Reference
UINT
(UGR) Decimal scale
factor used to convert
PV to “real world”
pressure. Pressure =
PV / UGR. Note that the
UGR is fixed for each
transducer range.
13
Get
AlarmTripPointHigh
UINT
Valid Range:
(ATPH) If AlarmEnable
is set and PV >= ATPH,
(WTPH - Alarm Hysteresis)
TripAlarmHigh is set
<= ATPH <= Overrange
(see Attr 05).
TripAlarmHigh is cleared
once PV <= ATPH –
AlarmHysteresis
(see Attr 15)
14
Get/Set
AlarmTripPointLow
UINT
Valid Range:
(ATPL) If AlarmEnable
is set and PV <= ATPL,
Underrange <= ATPL <=
TripAlarmLow is set
(WTPL - AlarmHysteresis)
(see Attr 05).
TripAlarmLow is cleared
once PV >= ATPL +
AlarmHysteresis (see Attr 15).
15
Get/Set
AlarmHysteresis
UINT
Valid Range:
The amount by which
PV must recover to clear
AlarmHysteresis <=
either TripAlarmHigh or
(ATPH - WTPH) or
TripAlarmLow.
(WTPL - ATPL)
16
Get/Set
AlarmSettlingTime
UINT
Units are in milliseconds
The time that the PV
must exceed the trip point
before TripAlarmHigh or
TripAlarmLow is set.
