2. BACNET - GENERAL INFO
BACnet stands for ‘Building Automation and Control Networks’. It is the common name for the 
communication standard ISO 16484-5 which defines the methods and the protocol for cooper-
ating building automation devices to communicate. Devices can be designed to operate using 
BACnet communication protocol as well as utilising BACnet protocol to communicate between 
systems. BACnet is an internationally accepted protocol for building automation (e.g. lighting 
control, air conditioning and heating automation) and control over a communications network.
BACnet provides a method by which computer-based control equipment, from different manu-
facturers can work together, or 'interoperate'. For this to be achieved, components must be able 
to exchange and understand BACnet data messages.
Your SmartVFD HVAC/SmartDrive HVAC AC drive is equipped with BACnet support as stan-
dard.
