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
15
Get/Set
Speed Range
Enable
BOOL
Indicates whether this
alarm is enabled only
within a certain machine
speed range.
0 = No speed range (alarm is
always enabled)
1 = Speed range (alarm only
enabled within speed range)
16
Get/Set
Speed Range
High
REAL
Indicates the greater
threshold of the machine
speed range for which the
alarm is enabled (disabled
at greater speeds).
CPM
(must be greater than Speed
Range Low)
