The information in this page is updated in accordance with firmware version .

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 System → [[{{{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 port integer [1..65535]; default: 47809 BACnet broadcast management devices port.
BBMD interface network interface; default: eth0 Specifies interface for BBMD function. IP address of this interface should be reachable from WAN.
Allow Remote Access 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.

BDT Configuration

This section contains Broadcast Distribution Table (BDT) configuration, where you specify the list of BBMDs (BACnet Broadcast Management Devices) responsible for forwarding broadcast messages between different subnets in a BACnet/IP network.

Field Value Description
IP address ipv4; default: none IP addresses of the BBMDs in the network.
Port integer [1..65535]; default: none Port numbers on which the BBMDs listen for BACnet/IP messages.
Netmask netmask; default: none Subnet masks used by the BBMDs to determine the range of IP addresses within a subnet.
Actions -interactive button; default: delete Deletes BDT configuration.

BIP Configuration

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

Field Value Description
Network ID integer [1..65535]; default: 1 Unique identifier for the BACnet/IP subnet within the entire BACnet internetwork.
Port integer [1..65535]; default: 47808 This specifies the port number used by BACnet/IP devices for communication.
Device interface; default: br-lan Select the network device to be used for BACnet/IP communication.
Actions -interactive button; default: delete Deletes BIP configuration.

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
Network ID integer [1..65535]; default: 2 Unique identifier for the BACnet MSTP network.
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..
