6 Get Threshold Units USINT Indicates whether the
threshold and hysteresis
value are specified in
units of measure.
Set to 1
1 = Measurement units
7 Get/Set Condition USINT Indicates on which side of
the threshold values the
alarm and danger
conditions exist.
0 = Greater than
1 = Less than
2 = Inside range
3 = Outside range
8 Get/Set Alert Threshold
(High)
REAL The threshold value for
the alert (alarm) condition
(greater threshold for
range types).
9 Get/Set Danger Threshold
(High)
REAL The threshold value for
the danger (shutdown)
condition (greater
threshold for range types).
10 Get/Set Alert Threshold
Low
REAL The lesser threshold value
for the alert (alarm)
condition for the range
condition types.
11 Get/Set Danger Threshold
Low
REAL The lesser threshold value
for the danger (shutdown)
condition for the range
condition types.
12 Get/Set Hysteresis REAL The amount on the safe
side of a threshold by
which the value must
recover to clear the alarm.
13 Get/Set Threshold (Setpoint
Multiplier)
REAL Indicates how the
thresholds should be
adjusted when the
setpoint multiplication
function is invoked.
0 = Disable alarm
> 0 = Multiply the thresholds by
the value
14 Get/Set Startup Period UINT The amount of time that
the Threshold (Setpoint)
Multiplier is applied after
the startup signal is
received.
Seconds
18 Get/Set Name STRING2 A name to help identify
this alarm.
