Events of any subtype of ConditionTypeare designated COM Condition Events and are subject to additional processing due to the stateful nature of Condition Events. COM Condition Events transition between states composed of the triplet ENABLED|ACTIVE|ACKNOWLEDGED. In UA A & C, Eventsubtypes of ConditionTypeonly carry a value which can be mapped to ENABLED (DISABLED) and optionally, depending on further sub typing, may carry additional information which can be mapped to ACTIVE (INACTIVE) or ACKNOWLEDGED (UNACKNOWLEDGED). Condition Eventprocessing proceeds as described in Table D.5(see A&E ONEVENTSTRUCT “Attribute” rows: OPC_CONDITION_ACTIVE, OPC_CONDITION_ENABLED and OPC_CONDITION_ACKED).
