This specification was created by a joint working group of the OPC Foundation and BACnet Interest Group Europe. It defines an OPC UA Information Model to represent the BACnet architectural models.

Typical use cases include but are not limited to SCADA connectivity, enterprise integration of building automation networks and data and interfacing between industry and building automation.

OPC Foundation

The OPC Foundation defines standards for online data exchange between automation systems. They address access to current data (OPC DA), alarms and events (OPC A&E) and historical data (OPC HDA). Those standards are successfully applied in industrial automation.

The new OPC Unified Architecture (OPC UA) unifies the existing standards and brings them to state-of-the-art technology using service-oriented architecture (SOA). Platform-independent technology allows the deployment of OPC UA beyond current OPC applications only running on Windows-based PC systems. OPC UA can also run on embedded systems as well as Linux / UNIX based enterprise systems. The provided information can be generically modelled and therefore arbitrary information models can be provided using OPC UA.

BACnet Interest Group Europe

The BACnet Interest Group Europe (BIG-EU) was founded in 1998 as an association under German law and meanwhile represents BACnet activities all over Europe.

BIG-EU has more than 115 members: vendors, project designer, system integrators and end-users of BACnet systems.

The working group marketing (WG-M) organizes events like forums, trade-shows, etc. while the working group technique supports technical activities like specifications or enhancements of the BACnet standard.

BIG-EU closely collaborates with the ASHRAE/SSPC-135 and BACnet International with the BACnet Testing Laboratories working group BTL-WG.

The BACnet Academy offers BACnet training courses all over Europe.

The BACnet Europe Journal issued twice a year by the BACnet Interest Group Europe is a popular magazine about European BACnet activities.
