DESCRIPTION

EVENT-TYPE

This sensor monitors the core activity For example: Description: Event Enrollment

This read only property, of type BACnetEventType, indicates the type of event algorithm that is to be used to detect the occurrence of events and report to enrolled devices.

For example: 0

NOTIFY-TYPE

Integer

This property, of type BACnetNotifyType, shall convey whether the notifications generated by the monitoring algorithm specified by the Event_Type property should be Events or Alarms.

For example: 2

EVENT-PARAMETERS

String

[Choice]|[Time-Delay]| [Bitmask]|[List-Of-

Bitstring-Values]

The Event_Parameters property, of type BACnetEventParameter, determines the algorithm used to monitor the referenced object and provides the parameter values needed for this algorithm.

For example: COB|10|10101010| 10101010;10101010;10101010

OBJECT-PROPERTY-REFERENCE

EVENT-STATE

String

[OBJECT-IDENTIFIER] | [PROPERTY-IDENTIFIER]

| [PROPERTY-ARRAY-INDEX

(Optional)] | [DEVICE- IDENTIFIER (Optional)]

Integer

This property, of type BACnetDeviceObjectPropertyReference, designates the particular object and property referenced by this Event Enrollment object. The algorithm specified by the Event_Type property is applied to the referenced property in order to determine the Event_State of the event.

For example: 29,4194303|29|786|30,4194303

This property, of type BACnetEventState, contains the current state of the event.

For example: 0

EVENT-ENABLE

3 Boolean values (1 = true, 0 = false) encoded as a string

{to-offnormal, to- fault, to-normal}

This property, of type BACnetEventTransitionBits, conveys three flags that determine whether notifications are enabled for TO-OFFNORMAL, TO-FAULT, and TO-NORMAL transitions.

For example: 101

ACKED-TRANSITIONS

3 Boolean values (1 = true, 0 = false) encoded as a string

{to-offnormal,to-fault,to-normal}

This property, of type BACnetEventTransitionBits, shall convey three separate flags that each indicate whether the most recent TO-OFFNORMAL, TO-FAULT, or TO- NORMAL event transitions have been acknowledged, if acknowledgment is required for that transition.

For example: 111

NOTIFICATION-CLASS

Integer

This property, of type Unsigned, implicitly references a Notification Class object in the device containing the Event Enrollment object.

For example: 0

EVENT-TIME-STAMPS

PROFILE-NAME

Sequence of time stamps encoded as a string

String

This property, of type BACnetARRAY[3] of BACnetTimeStamp, shall convey the times of the last event notifications for TO-OFFNORMAL, TO- FAULT, and TO-NORMAL events, respectively.

For example: 2|1-1-1970 11:0:0.0;2|1-1-1970 11:0:0.0;2|1-1-1970 11:0:0.0
