Intrinsic Alarming extension properties - Technical Manual - PXC4.E16.A - PXC7.E400.A

Acked-Transitions

AckTra

Acknowledged transitions

Indicates which of the transitions have been acknowledged; TO_OFFNORMAL, TO_FAULT, TO_NORMAL.

Deadband

HysToNrml

Hysteresis to normal

Represents a deadband applied to an alarm limit when determining return to normal conditions:
HIGH_LIMIT - present-value is less than (high-limit - deadband) for a time interval specified by time-delay-normal.

LOW_LIMIT - present-value is greater than (low-limit + deadband) for a time interval specified by time-delay-normal.

Ack-Credentials

AckCrdtl

Acknowledgement credentials

Identifies the user or process that acknowledged the most recent TO-OFFNORMAL, TO-FAULT, and TO-NORMAL event notifications.

Ack-Time-Stamps

TiAck

Time of acknowledgement

Conveys the acknowledgment times of the last TO_OFFNORMAL, TO_FAULT, and TO_NORMAL events.

event-algorithm-inhibit

SupEvtDet

Suppress event detection

Indicates whether (true) or not (false) the event algorithm has been disabled for the object. This property is a runtime override that allows temporary disabling of the event algorithm

Event-Notification-Inhibit

SupEvtNotf

Suppress event notification

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

Event_detection_enable

EnEvtDet

Enable event detection

Indicates whether (true) or not (false) intrinsic reporting is enabled in the object.

Event_Enable

EnEvt

Event enable

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

event-message-texts

EvtMsg

Event message texts

Character string, that conveys the message text values of the last TO_OFFNORMAL, TO_FAULT, and TO_NORMAL events generated for this object.

event-message-texts-config

EvtMsgCnf

Configurable event message texts

Contains character strings for the 'Message Text' or substitution codes for event notifications of TO_OFFNORMAL, TO_FAULT, and TO_NORMAL events.

Event_Time_Stamps

TiStmEvt

Time stamp of event

Timestamps of the following event transitions,  TO_OFFNORMAL, TO_FAULT, TO_NORMAL.

High_Limit

HiLm

High Limit

Specifies the upper limit of the present-value property's normal range

Limit_Enable

EnLm

Limit enable

A writable standard BACnet bitstring property, of type BACnetLimitEnable, specifies two flags, HighLimitEnable and LowLimitEnable, that separately enable (TRUE) or disable (FALSE) the respective limits applied by the event algorithm.

notification-class

NotifCl

Notification class

Specifies the instance of the Notification-Class object to use for event-notification-distribution.

notify-type

NotifTyp

Notification type

Always = Alarm
Specifies whether notifications generated by the object should be marked as Events or Alarms.

Status_Flags

StaFlg

State flag (*A* or –N-)

This is a standard base property that's included with the object regardless of whether intrinsic alarming is enabled or not

Logical FALSE (0) if the Event_State property has a value of NORMAL, otherwise logical TRUE (1). 
Logical TRUE (1) if the Reliability property is present and does not have a value of NO_FAULT_DETECTED, otherwise logical FALSE (0).

OVERRIDDEN = true if point is in hand mode, else false.

Logical TRUE (1) if the Out_Of_Service property has a value of TRUE, otherwise logical FALSE (0).

time-delay

TiMonDvn

Monitoring time deviation

Used for Alarming; represents a deadband time, in seconds, that must pass between the time that an object first detects an offnormal condition and a to-offnormal event state transition occurs.

time-delay-normal

TiMonDvnNm

Monitoring time deviation to normal

Used for Alarming; 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.
