at the end of the sampling interval.
Delta: Subtracts the last sampled value from the current
value. The difference in the values is compared to the
threshold.
Rising Threshold: Enter the rising counter value that triggers the Rising Threshold
alarm.
Rising Event: Select the index of the corresponding event which will be
triggered if the sampled value is larger than the Rising
Threshold.
Falling Threshold: Enter the falling counter value that triggers the Falling Threshold
alarm.
Falling Event: Select the index of the corresponding event which will be
triggered if the sampled value is lower than the Falling
Threshold.
Alarm Type: Specify the type of the alarm.
All: The alarm event will be triggered either the sampled
value exceeds the Rising Threshold or is under the Falling
Threshold.
Rising: When the sampled value exceeds the Rising
Threshold, an alarm event is triggered.
Falling: When the sampled value is under the Falling
Threshold, an alarm event is triggered.
Interval: Enter the alarm interval time in seconds.
Owner: Enter the name of the device or user that defined the entry.
Status: Enable/Disable the corresponding alarm entry.
Note:
When alarm variables exceed the Threshold on the same direction continuously for several times,
an alarm event will only be generated on the first time, that is, the Rising Alarm and Falling Alarm
are triggered alternately for that the alarm following to Rising Alarm is certainly a Falling Alarm and
vice versa.
