Building Automation Protocol

BACnet

Engineered for building-services automation with a standardised, object-oriented model exposing Analog Inputs, Schedules, Binary Outputs and loop-control values natively.

Type

Building Automation Protocol

Typical Latency

20ms–150ms.

Hardware Requirements

MS/TP over RS485 (9600–76800 bps) or BACnet/IP over standard networks, UDP port 47808.

Security

BACnet Secure Connect (BACnet/SC) adds TLS 1.3 encapsulation, certificate validation and secure WebSocket transport.

Typical Use Case

Chiller-plant coordination, centralised HVAC/ventilation, VAV controllers, fire-alarm tracking arrays.

Connection Parameters

Default port
UDP 47808 (0xBAC0)
Network types
BACnet/IP, MS/TP, BACnet over Ethernet
Object types
Analog Input/Output, Binary Value, Device Object
Discovery
Who-Is / I-Am dynamic binding
