Abstract:

The BACnet standard defines classes of conformance and other collections of protocol functionality. Since a product need not support all of the capabilities of the protocol in order to conform to the standard, a manufacturer must select conformance classes and functional groups appropriate for the application the product is intended to meet. A system integrator must also understand these classifications in order to prepare procurement specifications. The standard does not contain test procedures for determining if a device conforms to the standard. In 1993 the NIST BACnet Interoperability Testing Consortium was formed, in part to develop procedures and tools to test the conformance and interoperability of BACnet products. This paper describes BACnet conformance classification issues and the work of the NIST consortium in developing testing tools and applying them to test products made by member companies.
