BACnet MS/TP—On-Board Communication
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 cooperating building automation devices to
communicate. Devices can be designed to operate using
BACnet communication protocol as well as utilizing BACnet
protocol to communicate between systems. BACnet is an
internationally accepted protocol for building automation
(such as lightning control, air conditioning and heating
automation) and control over a communications network.
BACnet provides a method by which computer-based control
equipment, from different manufacturers can work together,
or "interoperate". For this to be achieved, components must
be able to exchange and understand BACnet data messages.
Your G-Max HVAC drive is equipped with BACnet support as
standard.
BACnet MS/TP Connections
The control board is located inside the control unit of the DG1 Series Drive.
