Approach for automatically setting the device instance of a BACnet device

摘要

An approach for automatically setting the device instance of a device such as a unitary controller without reliance on a router and/or global controller, or something like a special extension to an associated router and/or global controller. The approach may be implementable entirely by logic in the unitary controller.

1. A device instance setting mechanism comprising:
a building and automation control network; a global controller connected to the network, wherein the global controller has a global controller identifier; and at least one unitary controller connected to the network, wherein each of the at least one unitary controllers includes a unique device instance; and wherein each of the at least one unitary controllers receive the global controller identifier via the network, and automatically generate the unique device instance of the corresponding at least one unitary controller based, at least in part, on the global controller identifier.
