All BACnet objects are required to support ? properties. | Object_Identifier Object_Name Object_Type |
What do the top 10 bits of the Object_Identifier represent? | An enumeration code for the object type |
The character string contained in the ? property provides a human-readable way to identify the object. | Object_Name |
Which of the following is not one of the nine BACnet standard object types that are commonly referred to as the basic object types? | Single-State input |
What special type of object is every BACnet node required to support? | Device object |
The Object_List is an array property of the Device object that contains the ? of all of the objects within the node. | Object_Identifiers |
Analog quantities represent a value within a range of possible values, such as ? | humidity, lighting luminance, pressure, and temperature |
What is the principal property of the Analog Input, Analog Output, and Analog Value objects? | Present_Value property |
Writing a different value to the Present_Value property of an Analog Output causes the associated physical output (or process) to ? | change |
