ASHRAE Committee SSPC-135 Submits XML/Web Services Addendum to BACnet Standard for Public Review
An XML/Web Services Addendum to ASHRAE Standard 135-2004, BACnet® was submitted for public review by ASHRAE committee, SSPC-135 as Annex M (BACnet/WS). Web services are a collection of technologies that allow different applications from different sources to communicate with each other without time-consuming custom coding. Because all communication is in XML, web services are not tied to any particular operating system or programming language.
The services described in Annex M provide a universal standard for data sharing, alarming, and trending of building data using XML and SOAP; providing a high level abstraction of building automation and control network data for use with other systems such as utilities, weather, and financial systems. Since this addendum includes normalized data types, it can also be used to bridge the gap between different building protocols including BACnet, MODBUS, LON® or even proprietary protocols.
