Configuring Point Alarms

Any point in a PNT can be configured to report alarms. Alarms are reported on a per-point, per-alarm basis.

Alarm States

In the point properties, enable each alarm state that you want to be active.

Point Type	Alarm States
Analog	Analog points have the following possible alarm types. High Alarm High Warning Low Alarm Low Warning Out-of-Range (High or Low) High Deviation See Analog Points in the Alarms section and Analog Point Properties for more information.
Digital	Digital points have the following possible alarm types. Chattering Digital Alarm Digital Warning See Digital Points in the Alarms section and Digital Point Properties for more information.
Enumeration	Enumeration points have the following possible alarm types. Enumeration Alarm 6 Enumeration Alarm 5 Enumeration Alarm 4 Enumeration Alarm 3 Enumeration Alarm 2 Enumeration Alarm 1 Note: For this point type, only values from the enumeration table can be selected as alarms. The alarm number denotes no hierarchy. However, you may want to select specific alarms based on their preset alarm colors. Example The assigned color for Alarm 1 is magenta, which represents "unreliable" for all other points. Although you cannot change the preset color, the alarms are not hierarchical, so you can select Alarms 2, 5, or 6, which all have a preset color of red. See Enumeration Points in the Alarms section and Enumeration Point Properties for more information.
String	String points have the following possible alarm types. String Alarm 6 String Alarm 5 String Alarm 4 String Alarm 3 String Alarm 2 String Alarm 1 The alarm number denotes no hierarchy. However, you may want to select specific alarms based on their preset alarm colors. Example The assigned color for Alarm 1 is magenta, which represents "unreliable" for all other points. Although you cannot change the preset color, the alarms are not hierarchical, so you can select Alarms 2, 5, or 6, which all have a preset color of red. See String Points in the Alarms section and String Point Properties for more information.

Alarm Reporting

Alarms can be active without reporting alarms to the Common Alarm Service. If the Report Alarms option is disabled but an individual alarm type is enabled, that alarm will be active although not reported. For example, you would see that the point’s current state is in an alarm condition, but you would not see the alarm in the Common Alarm Service.

Alarm Priority

You can assign a priority to alarms for a point. The priority range is 0-99, with 99 being the highest priority. Assigning a priority is useful for sorting and viewing alarms.

Alarm Delay

Alarms also have a Delay Reporting feature. An alarm condition must exist for a time equal to the "Delay Reporting" setpoint (hh:mm:ss) in order for the alarm to be set.

Alarm Deadband

For analog points, an Alarm Deadband option can be configured. Once an alarm is set, the point’s value must exceed the alarm setpoint by the deadband value to clear and reset the alarm.
