Station alarm roll-ups

For each station record, the monitorAlarmRollUp application automatically rolls ups the alarm counts for each alarm category based on the existing alarms associated with that station in the alarm summary.

The following information is kept in each station record:

• Highest active alarm severity at the station (mostSevAlm)

• Color of highest active alarm severity (mostSevAlmCol)

• Number of alarms of each severity (alarm_counts)

  Note: When a station’s highest active alarm severity is changing, the associated record on the Station Summary window will flash and change color.

Refer to the following table to determine which element in the alarm_counts array field contains the count for which severity.

Note: You can configure alarm colors via the Xosalmattr table. The table above lists the default alarm severity colors.

If, for example, an analog record associated with a station record enters a High alarm state, the application increments by one the "20" alarm count index.

The color of a particular station display depends on the highest alarm severity among the various point values that appear on the display. If the curval value of the analog record in this scenario appears on a station display, the color of the station display changes to red, assuming that it represents the highest alarm severity among the various point values.

Note: For information on changing the colors associated with alarm severities, refer to Message table.

The following table shows the relationship between fields on the Station Summary window, which displays the number of alarms for each alarm category, and the corresponding internal fields.

For example, the path to the internal station table field for UnAcked Low would be <station>.<record>.alarm_counts[5].
