VENDOR IDS
BACnet provides facilities by which "private," i.e., non-standard, information may be transported. In order to arbitrate between non-standard messages of different manufacturers, BACnet defines a numerical "vendor identifier." Vendor IDs are available to any BACnet implementor without cost. For details on how to obtain a Vendor ID, please click here.
