MS/TP FRAME TYPES
BACnet provides facilities by which "private," i.e., non-standard, information may be transported on MS/TP networks by using "proprietary frame types". However, it may also be desirable for other standards organizations to be able to define data formats that, while not defined by BACnet itself, are nonetheless published and "standardized" and are thus not considered truly "proprietary". In order to support the definitions of such formats, BACnet reserves a numerical range of its standard frame types that can be assigned to other organizations.
