Description: Type of operation which determines when an alarm is to be cleared.

Definition of each type is as follows:

lt - Measured objects value is less than clear threshold gt - Measured objects value is greater than clear threshold le - Measured objects value is less than or equal to clear threshold ge - Measured objects value is greater than or equal to clear threshold eq - Measured objects value is equal to clear threshold neq - Measured objects value is not equal to clear threshold

The alarm operation defines how to apply the configured thresholds when clearing the alarm. This defines whether the alarm is cleared when the measured object value crosses the threshold from low to high or from high to low or if the measured value hits a certain value or not.

Example:

Alarm Name Alarm Threshold Clear Operation High Temperature 60 le Low Temperature -30 gt

Low Temperature Alarm is cleared when the measured temperature is lower or equal to 60 and Low Temperature cleared when the measured temperature is greater than -30.
