Summary

BACnet is a communication protocol for building automation and control (BAC) networks that use the ASHRAE, ANSI, and ISO 16484-5 standards protocol.

This manual page provides an overview of the BACnet functionality in {{{name}}} devices.

Note: BACnet is additional software that can be installed from the Services → [[{{{name}}} Package Manager|Package Manager]] page.

General Configuration

Field	Value	Description
Enable	off \| on; default: off	Enables BACnet router function.
Enable BBMD	off \| on; default: off	Enables BACnet broadcast management function.
BBMD interface	network interface; default: eth0	Specifies interface for BBMD function. IP address of this interface should be reachable from WAN.
Port forward	off \| on; default: off	Creates port forward firewall rule to make application port in LAN reachable from selected BBMD interface.
Force gateway	off \| on; default: off	Adds configured gateway IP address and port to BBMD packages sent.
Gateway address	ip4; default: none	Gateway IP address.
Gateway port	integer [1..65535]; default: none	Gateway port number.

BIP Configuration

Communications in BACnet over IP (BIP) rely upon the protocol rules of IP and Ethernet.

Field	Value	Description
BIP port	integer [1..65535]; default: 47808	BIP UDP port.

MSTP Configuration

MSTP is most commonly used to connect field devices to controllers / routers / control applications. The physical layer uses RS485 which allows up to 31 devices to be installed on a single network.

Field	Value	Description
MSTP MAC	integer [0..127]; default: 13	Router MSTP MAC address.
MSTP MAC max	integer [1..127]; default: 127	Maximum client address in the MSTP network.
Baud rate	300 \| 600 \| 1200 \| 2400 \| 4800 \| 9600 \| 19200 \| 38400 \| 57600 \| 115200 \| 230400; default: 38400	Serial data transmission rate (in bits per second).
Parity	Even \| Odd \| Mark \| Space \| None; default: None	In serial transmission, parity is a method of detecting errors. An extra data bit is sent with each data character, arranged so that the number of 1 bits in each character, including the parity bit, is always odd or always even. If a byte is received with the wrong number of 1s, then it must have been corrupted. However, an even number of errors can pass the parity check. None (N) - no parity method is used. Odd (O) - the parity bit is set so that the number of "logical ones (1s)" has to be odd. Even (E) - the parity bit is set so that the number of "logical ones (1s)" has to be even. Space (S) - the parity bit will always be a binary 0. Mark (M) - the parity bit will always be a binary 1.
Data bits	5 \| 6 \| 7 \| 8; default: 8	Number of data bits for each character.
Stop bits	1 \| 2; default: 1	Stop bits sent at the end of every character allow the receiving signal hardware to detect the end of a character and to resynchronise with the character stream. Electronic devices usually use one stop bit. Two stop bits are required if slow electromechanical devices are used..
