The BACnet Manufacturers Association (BMA) (Boston) and the BACnet Testing Laboratories (BTL) recently held the second BMA-sponsored BACnet Interoperability Workshop which was hosted by Teletrol Systems Inc. in Manchester, N.H.

Twelve BMA corporate members, including Alerton Technologies Inc., Automated Logic Corp., Cimetrics, Delta Controls, Johnson Controls Inc., Lithonia Lighting, McQuay International, Reliable Controls, Siemens Building Technologies, Teletrol Systems Inc., The Trane Company, and The Watt Stopper, participated in the interoperability testing.

The participants tested the BACnet interoperability of their building automation hardware and software products in five functional areas: data sharing, alarming, scheduling, trending, and device management. A wide-range of products were present, ranging from full-featured operator workstations to unitary controllers and networked I/O. Representatives from Cornell University and the National Institute of Standards and Technology (N.I.S.T.) also attended, adding their BACnet expertise to the event.
