AP WORKING GROUP
The goal of this group is to investigate the development of "macro" object types suitable for various application areas as well as other ways to extend the BACnet standard in backward-compatible ways.
This group is studying a proposal for a "BACnet Modeling Language" that is expected to provide a machine-readable way of representing the capabilities of individual BACnet devices such as services and objects supported. A new standard object property called "Profile_Name" now allows the extension of standard (or proprietary) object types in such a way that devices with knowledge of the named profile are able to interpret the extended properties. This is expected to form the basis for convenient BACnet interfaces to other protocols that support object-oriented representation of their functionality.
