◊ Delete Click the Delete button to remove an entry. Following are descriptions for the categories shown in the Alarm Table: ♦ Owner The entity that configured the entry and is therefore using the resources assigned to it. ♦ Index An index uniquely identifying an entry in the alarm table. Each such entry defines a diagnostic sample at a particular interval. ♦ Interval The interval in seconds over which the data is sampled and compared with the rising and falling thresholds. When setting this variable, care should be taken in the case of Delta sampling - the interval should be set short enough that the sampled variable is very unlikely to increase or decrease by more than 2^31 − 1 during a single sampling interval. ♦ Variable The object identifier of the particular variable to be sampled. ♦ Sample Type The method of sampling the selected variable and calculating the value to be compared against the thresholds. If the value of this object is Absolute, the value of the selected variable will be compared directly with the thresholds at the end of the sampling interval. If the value of this object is Delta, the value of the selected variable at the last sample will be subtracted from the current value, and the difference compared with the thresholds.
