BACnet property

Short Name

BACnet Description

Notes

event-type

EvtTyp

Event type

A read-only property that indicates the event algorithm to be used by this Event-Enrollment object instance. The value of this property is determined by the selected Alarm-Extension [Change-Of-State, Out-Of-Range, Command-Failure, and Floating-Limit].

notify-type

NotifTyp

Notification type

A writable standard BACnet enumerated property that specifies whether notifications generated by the object should be marked as Events or Alarms.

event-parameters

EvtPars

Event Parameters

A read-only standard BACnet property that provides the parameter values needed for this Event-Enrollment object's event algorithm. The event-parameters property is a complex ASN.1 tagged sequence, the content of which varies based on the selected event-type.

object-property-reference

ObjPrpr

Object property reference

A read-only standard BACnet property that indicates the object property's value to be tested for alarm conditions.

Object-Name-Reference

ObjNameRef

Object name reference

A writable proprietary property that references the data source object for this Event-Enrollment object instance.

Source-Property-Identifier

SrcPrpyId

Source property identifier

A read-only proprietary property that specifies the data source property for this Event-Enrollment object instance. Property-Identifier may be displayed as a BACnetPropertyId (85). The default is PrVal.

event-state

EvtSta

Event state

A read-only standard BACnet enumerated property that represents the event/alarm state of the object.

event-enable

EnEvt

Event enable

A writable BACnet standard bitstring property consisting of shall three flags that separately enable and disable the distribution of notifications:
TO_OFFNORMAL, TO_FAULT, and TO_NORMAL.

acked-transitions

AckTra

Acknowledged transitions

A read-only standard BACnet bitstring property that conveys three flags that separately indicate the acknowledgment state for events:
TO_OFFNORMAL, TO_FAULT, and TO_NORMAL.

Ack-Credentials

AckCrdtl

Acknowledgement credentials

A read-only proprietary property, consisting of three character strings, identifying the user or process that acknowledged the most recent event notifications:
TO-OFFNORMAL, TO-FAULT, and TO-NORMAL.

Ack-Time-Stamps

TiAck

Time of acknowledgement

A read-only standard BACnet property, consisting of three time-date stamps, that conveys the acknowledgment times of the last events:
TO_OFFNORMAL, TO_FAULT, and TO_NORMAL.

notification-class

NotifCl

Notification class

A writable BACnet standard Unsigned property that specifies the instance of the Notification-Class object.

event-time-stamps

TiStmEvt

Time stamp of event

A read-only standard BACnet property that conveys the times of the last events:
TO_OFFNORMAL, TO_FAULT, and TO_NORMAL.

event-message-texts

EvtMsg

Event message texts

A read-only standard BACnet property that conveys the message text values of the last events generated for this object:
TO_OFFNORMAL, TO_FAULT, and TO_NORMAL.

event-message-texts-config

EvtMsgCnf

Configurable event message texts

A writable standard BACnet property that contains the character strings for the Message Text for the event notifications generated by this object.

event-detection-enable

EnEvtDet

Enable event detection

A read-only standard BACnet Boolean property, that indicates whether (true) or not (false) alarm reporting is enabled. In PXC.A Event-Enrollment objects, event-detection-enable is always true.

event-algorithm-inhibit

SupEvtDet

Suppress event detection

A writable standard BACnet Boolean property that indicates whether (true) or not (false) the event detection algorithm has been disabled for the object at runtime.

Event-Notification-Inhibit

SupEvtNotf

Suppress event notification

A writable proprietary property allowing event notification functionality to be temporarily disabled for the object instance at runtime.

time-delay-normal

TiMonDvnNm

Monitoring time deviation to normal

A writable BACnet standard Unsigned property that represents a deadband time, in seconds, that must pass between the time that an object first detects a normal condition and a to-normal event state transition occurs.

status-flags

StaFlg

State flag

A read-only standard BACnet bitstring property composed of four Boolean flags that indicate the general health of the object.

reliability

Rlb

Reliability

A read-only standard BACnet enumerated property that provides an indication of whether the present-value or the operation of the physical input/output in question is reliable as far as the BACnet device or operator can determine and, if not, why.

Alarm-Extension

AlarmExtn

Event configuration

A writable proprietary enumerated property that specifies which PXC.A EEO alarming extension is enabled for the object. Supported extensions:
Unused, Change-Of-State, Out-Of-Range, Command-Failure, Floating-Limit.
