BACnet Standard

BACnet Standard

A standardized protocol

BACnet (Buildinf Automation Control network) was initially designed by and for BMS (Building Management System) professionals (ASHRAE) seeking to build a vendor-independent communication and control system. OPC (OLE for Process Control) did not exist at the time, and BACnet provided revolutionary possibilities:

  • Native Bacnet  SCADA
  • Communication via notification,
  • Command prioritization,
  • Advanced management of alarms, schedules, etc.,
  • Object-oriented programming for reading, writing, and creating objects,
  • Network device discovery,
  • Standardized but open design,
  • etc.

Although originally conceived in 1987, the first version of BACnet was not released until 1996. The solution really took off in 2005 as major vendors became interested. Today BACnet covers other types of application related to BMS: access control, fire safety, etc. BACnet is more than just a protocol—it is a full-fledged ANSI and ISO standard.

Interoperability with Panorama COM SCADA System

 BACnet and Panorama COM have many points in common:

  • Object-oriented programming,
  • Notification when values change (BACnet COV),
  • Open architecture,
  • Easy implementation.

In order to maintain all of BACnet's advantages, it was vital to enable native integration without going through an intermediate gateway. The design of Panorama made it easy for us to create a new BACnet configuration import tool. The tool makes it possible to automatically generate a Panorama application based on the discovery of the BACnet network. In 2010 we added support for BBMD (BACnet/IP Broadcast Management Device) in order to enable communications over the Internet for large installations distributed across multiple sites. All BACnet services are native in Panorama E² and Panorama COM.
