A BACnet object is analogous to a System 600 APOGEE point. BACnet identifies each object
by its object type enumeration and an instance number. Each instance number is unique for
any particular object type across an entire network of BCUs. This assumption allows for
mapping BACnet objects directly into a System 600 APOGEE point number.
Trane expresses object addresses through the following notation:
XX-00-00-YY
Where XX is the Object Type Enumeration as shown in Table 4-6 and YY is the object's
instance number.

For this example, assume the following:
For Trane:

The device address of the BCU is 1.
