Appendix 2 Details of BACnet Properties
Description
BinaryInput object
BACnet device operating status, such as ON/OFF or
normal/error, is represented.

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 the value of the EventState property is other than Normal, this bit is True.
• Fault bit: When the value of the EventState property is Fault, this bit is True.
• Overridden bit: Always False.
• OutOfService bit: When the value of the OutOfService property is True, this bit is also True.
Whether or not the value set to the value of the PresentValue property is reliable is represented.
When the value of the Reliability property is NoFaultDetected, it indicates that a proper value is stored in the
PresentValue property.
The event status of an object (normal/alarm (event active)/failure) is represented.
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.)
Description
Multi-State Input object
The value for operating mode (cooling, heating, fanning, or dehumidifying mode) or wind speed (weak, medium, or
strong) is stored.


A maximum value of the PresentValue property is specified.
The value of the PresentValue property is changed from 1 to the value specified to a NumberOfStates.
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 the value of the EventState property is other than Normal, this bit is True.
• Fault bit: When the value of the EventState property is Fault, this bit is True.
• Overridden bit: Always False.
• OutOfService bit: When the value of the OutOfService property is True, this bit is also True.
Whether or not the value set to the value of the PresentValue property is reliable is represented.
When the value of the Reliability property is NoFaultDetected, it indicates that a proper value is stored in the
PresentValue property.
The event status of an object (normal/alarm (event active)/failure) is represented.
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.)
BinaryOutput object
BinaryValue object
The operating status of a BACnet device can be changed
by changing the property value of the BinaryOutput
object from another BACnet device, such as a central
monitoring device.
The value stored to the PriorityArray property whose
index number is the smallest among 16 arrays is the
value of the PresentValue property.
Multi-State Output object
The value stored to the PriorityArray property whose
index number is the smallest among 16 arrays is the
value of the PresentValue property.
The status of a BACnet device is stored.
If the value set to the PresentValue property and the
FeedbackValue property are different, the status will be in
alarm state.
