Since all Alarmsand Conditions Events belong to a subtype of BaseEventType, the A&E COM UA Proxy maps the subtype as received from the UA A & C Serverto one of the three A&E Eventtypes: Simple, Tracking and Condition. Figure D.2shows the mapping as follows:

• Those A & C Events which are of subtype AuditEventTypeare marked as A&E Eventtype Tracking.
• Those A & C Events which are ConditionTypeare marked as A&E Eventtype Condition.
• Those A & C Events which are of any subtype except AuditEventTypeor ConditionTypeare marked as A&E Eventtype Simple.

Note that the Eventtype mapping described above also applies to the children of each subtype.
