8 Get/Set AlarmHAlertLimit REAL The threshold value for the alert
state of the alarm. (For range
conditions, this is the greater
threshold value.)
9 Get/Set AlarmHDangerLimit REAL The threshold value for the Danger
state of the alarm. (For range
conditions, this is the greater
threshold value).
10 Get/Set AlarmLAlertLimit REAL The lesser threshold value for the
Alert state of the alarm with a range
condition type.
11 Get/Set AlarmLDangerLimit REAL The lesser threshold value for the
Danger state of the alarm with a
range condition type.
12 Get/Set AlarmDeadband REAL The amount on the safe side of a
threshold by which the value must
recover to clear the alarm.
13 Get/Set AlarmLimitMultiply (Setpoint
Multiplier) REAL Indicates how the threshold must be
adjusted when the Setpoint
multiplication function is invoked. 0 = Disable alarm
> 0 = Multiply the thresholds by the value
14 Get/Set AlarmLimitMultiplyPeriod UINT The amount of time that the
Threshold (Setpoint) Multiplier is
applied after the start-up signal is
received.
Seconds
15 Get/Set AlarmSpeedRangeEn 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 AlarmSpeedHLimit 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
AlarmSpeedLLimit )
17 Get/Set AlarmSpeedLLimit REAL Indicates the lesser threshold of the
machine speed range for which the
alarm is enabled (disabled at lesser
speeds). CPM
(Must be less than
AlarmSpeedHLimit )
18 Get/Set Name STRING2 A name to help identify this alarm.
19 Get/Set Measurement Identifier EPATH Identifies the measurement object
to which this alarm is applied. See Parameter Object instances 10…25. See
Table 56 on page 130 .
21 Get/Set Detection Delay UINT The period that the measurement
must violate the threshold before
the Alert or Danger status is
indicated.
0…65,530 ms
