Object_Identifier
Must be unique in BACnet network. As Object Identifier is 22 bits long
its value range is 0 ... 4194303. Each device is assigned a random value
in this range at Vaisala factory.
Object_Name
Must be unique in BACnet network. Default object name contains the
name and serial number of the device. For example:
- Device model is HMW95, with serial number G1234567.
- Object_Name is "HMW95_G1234567".
System_Status
System status can be OPERATIONAL (0) or NON-OPERATIONAL (4).
Device goes to NON-OPERATIONAL state in case of fatal error.
