# BACnet Model
BACnet model describes how InteractionAffordances are represented on BACnet. Essentially it is a [protocol binding for WoT TD via context extension](https://www.w3.org/TR/wot-thing-description/#adding-protocol-bindings).
Wherever possible, this model refers to ANSI/ASHRAE Standard 135-2020 for BACnet.

Additional parameters can be specified via URI variable syntax, e.g., `?commandPriority=13` to change command priority, `?relinquish` to relinquish a priority, or `?covIncrement=0.5` to increment COV.
