Appendix 2
This chapter describes the details on the BACnet properties used for the Ethernet module.
For details on the BACnet properties, refer to the standard that the Ethernet module conforms to.

Details of BACnet Properties
Description
The total amount of electrical energy is stored.
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/upper limit value error/lower limit value error/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
AnalogInput object
The value of an actual room temperature or preset
temperature 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/upper limit value error/lower limit value error/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.)
AnalogOutput object
AnalogValue object
The preset temperature can be changed by changing the
property value of the AnalogOutput 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.
