Device Object
The Device Object fully describes the BACnet device to the network. Notable is that the Device Object Instance ID and the
Device Object Name are configurable.
The Device Object Instance ID is a unique internetwork-wide numerical value. It is a 22-bit value that can range from 0 to
4,194,303. It is configurable by parameters Z3-08 and Z3-09. Any changes to these parameters will not take effect until the
power is cycled to the bypass.
The Device Object Name is a unique internetwork-wide character string. It is a 20-character string. It is writable from the
BACnet network. Any new string written will not take effect until the power is cycled to the bypass.
