Properties of a BinaryInput object and BinaryOutput object
Property name Description
PresentValue For a BinaryInput object, a BACnet device operating status, such as ON/OFF or normal/error, is represented.
For a BinaryOutput object, the operating status of a BACnet device can be changed by changing the property value of
a BinaryOutput object from another BACnet device, such as a central monitoring device.
PriorityArray Settable only for BinaryOutput objects.
The value stored to a PriorityArray property whose index number is the smallest among 16 arrays is a PresentValue
property value.
AlarmValue Settable only for BinaryInput objects.
When a PresentValue property value becomes the same as any of the values specified to an AlarmValues, an
EventState property value is changed to Offnormal.
FeedbackValue Settable only for BinaryOutput objects.
The status of a BACnet device is stored.
If the value set to a PresentValue property and a FeedbackValue property value are different, the status will be in alarm
state (EventState property value will be Offnormal.).
TimeDelay For a BinaryInput object, specify the time interval from when a PresentValue property value is matched to an
AlarmValue property value to when an EventState property value is changed to alarm state (EventState property value
is changed to Offnormal.).
For a BinaryOutput object, specify the time interval from when a PresentValue property value is mismatched with a
FeedbackValue property value to when an EventState property value is changed to alarm state (EventState property
value is changed to Offnormal.).
StatusFlags The current status of an object is represented. (Alarm/failure/under maintenance)
In a configuration function, InAlarm bit, Fault bit, Overridden bit, and OutOfService bit are displayed in order from left to
right.
• InAlarm bit: When an EventState property value is other than Normal, this bit is True.
• Fault bit: When an EventState property value is Fault, this bit is True.
• Overridden bit: Always False.
• OutOfService bit: When an OutOfService property value is True, this bit is also True.
Reliability Whether or not the value set to a PresentValue property is reliable is represented.
When a Reliability property value is NoFaultDetected, it indicates that a proper value is stored in the PresentValue
property.
EventState The event status of an object (normal/alarm (event active)/failure) is represented.
EventEnable Set whether to send an Event notification when an EventState property value is changed.
OutOfService When this property is set to True, it means that the device is under maintenance. (The property assigned to an object
or buffer memory is deallocated.)
ElapsedActiveTime The total time that the value of a PresentValue property has been 'Active' is stored. (Unit: seconds)
ChangeOfStateCount The total number of times when a PresentValue property is changed is stored.
