EventAlarmPriority

Description

The priority of an alarm is a measure of its importance relative to other alarms. The priority of an alarm is used to determine the order in which alarms are presented to the operator.

ID	Values	Descriptions
0	Undefined	No priority has been assigned to the alarm.
1	Low	The alarm is of low priority.
2	Medium	The alarm is of medium priority.
3	High	The alarm is of high priority.
4	Critical	The alarm is of critical priority.

EventAlarmSource

Description

The source of an alarm is the entity that is responsible for the alarm.

ID	Values	Descriptions
0	Undefined	No source has been assigned to the alarm.
1	FieldDevice	The alarm is generated by a field device.
2	ControlSystem	The alarm is generated by a control system.
3	HMI	The alarm is generated by a human-machine interface.
4	Internal	The alarm is generated by an internal source.

EventAlarmState

Description

The state of an alarm is a measure of the alarm's current status.

ID	Values	Descriptions
0	Undefined	No state has been assigned to the alarm.
1	Normal	The normal state should not use an audible indication. The normal state visual indication should be the same as indications without alarms.
2	Unacknowledged	The unacknowledged alarm state should use both an audible indication and visual indication. The audible indication should be silenced with a silence action or acknowledge action by the operator. The visual indication should be clearly distinguishable from the normal state indication by using colours and symbols (e.g., shape or text). The visual indication for an unacknowledged alarm should include a blinking element. There are some environments in which an audible indication is not an effective indicator of unacknowledged alarms.
3	Acknowledged	The acknowledged alarm state should not use an audible indication. The acknowledged alarm state visual indication should be clearly distinguishable from the normal state indication by using symbols (e.g., shape or text), and should be identical in colour to the unacknowledged alarm indication. A blinking element should not be used in the visual indication for an acknowledged alarm.
4	ReturnToNormal	The return-to-normal unacknowledged state should not use an audible indication. The return to-normal unacknowledged state visual indication may be the same as the normal state or it may indicate an unacknowledged status with a blinking element.
5	Shelved	The shelved alarm state should be visually indicated in the HMI. The visual indication for a shelved alarm should not include a blinking element. The shelved alarm state indication should be distinct. No audible indication should be used to identify shelved alarms.
6	SuppressedByDesign	The suppressed-by-design alarm state should be visually indicated in the HMI. The visual indication for an alarm suppressed by design should not include a blinking element. The suppressed-by-design alarm state indication should be distinct from the unacknowledged and acknowledged state indications. No audible indication should be used to identify alarms suppressed by design.
7	OutOfService	The out-of-service alarm state should be visually indicated in the HMI. The visual indication for an out-of-service alarm should not include a blinking element. The out-of-service alarm state indication should be distinct from the unacknowledged and acknowledged state indications. No audible indication should be used to identify out-of-service alarms.

EventAlarmType

Description

The type of an alarm is a measure of the nature of the alarm.

ID	Values	Descriptions
0	Undefined	No type has been assigned to the alarm.
1	Absolute	The alarm is based on an absolute value.
2	Deviation	The alarm is based on a deviation from a set-point.
3	RateOfChange	The alarm is based on the rate of change of a value.
4	Discrepancy	The alarm is based on a discrepancy between two values.
5	Calculated	The alarm is based on a calculated value.
6	RecipeDriven	The alarm is based on a recipe-driven value.
7	BitPattern	The alarm is based on a bit pattern.
8	ControllerOutput	The alarm is based on a controller output.
9	SystemDiagnostic	The alarm is based on a system diagnostic.
10	InstrumentDiagnostic	The alarm is based on an instrument diagnostic.
11	Adjustable	The alarm is based on an adjustable value.
12	Adaptive	The alarm is based on an adaptive value.
13	ReAlarming	The alarm is based on a re-alarming value.
14	Statistical	The alarm is based on a statistical value.
15	FirstOut	The alarm is based on a first-out value.
16	BadMeasurement	The alarm is based on a bad measurement.
