17.4 Object Types
Table 20 shows how MMX classifies its devices according to the BACnet object types.
17.5 Object Type Properties
Each of these object types has a set of properties, which identify the object and its state. Table
21 lists the properties associated with each BACnet object that MMX uses. Some of the
properties are static (they do not change), while others are dynamic (they change depending
on the state the object is in). The dynamic properties are bold.
