BACnet

BACnet is a communication protocol specifically designed for Building Automation and Control Networks. It is recognized by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers), ANSI (American National Standards Institute), and ISO (International Organization for Standardization). Here are its key characteristics:

1. Open source standard:

   • BACnet is an open standard, and no license fees are required for its implementation.

   • Many manufacturers have adopted these standards, reducing dependence on specific vendors.

2. Application scope:

   • BACnet facilitates communication among building automation and control systems.

   • It covers applications such as heating, ventilation, air conditioning control, lighting control, access control, fire detection systems, and associated equipment.

3. BACnet standardized device profile:
   The controller has undergone rigorous testing at the BACnet testing labs (BTL) and successfully meets all necessary interoperability requirements. You can find additional details and the results of the BTL testing on the BACnet website.

4. The controller configuration:

   • Interconnection between the controller and other BACnet devices occurs over the Ethernet physical layer.

   • The controller serves as a BACnet server, allowing data to be read by BACnet client devices and written to the server.

   • The connection to the BACnet network originates from KNX group objects in the controller.

5. Object export:

   • In the controller object list (Configurator → Objects), each KNX object has an Export parameter.

   • Selecting the Export checkbox makes the specific KNX object visible in BACnet as a BACnet object.

   • Binary objects appear as binary values, while numeric objects appear as analog values.

   • Other data types are not supported.
