ASHRAE Committee SSPC-135 Submits XML/Web Services Addendum to BACnet Standard for Public Review
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.
As part of the BACnet Standard, this addendum permits BACnet to be used at every level of the information hierarchy from a sensor or controller to a workstation or server and now other enterprise systems using XML.
Already several manufacturers have started implementing the XML/web services per this public review addendum, and compliant building control solutions should be available within the next year after the addendum is approved.
