The information in this page is updated in accordance with firmware version RUTX_R_00.07.22.1.

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 RUTX11 devices.
Note: BACnet is additional software that can be installed from the System → Package Manager page.

General Configuration

FieldValueDescription
Enableoff | on; default: offEnables BACnet router function.
Enable BBMDoff | on; default: offEnables BACnet broadcast management function.
BBMD portinteger [1..65535]; default: 47808BACnet broadcast management devices port.
BBMD interfacenetwork interface; default: br-lanSpecifies interface for BBMD function. IP address of this interface should be reachable from WAN.
Allow Remote Accessoff | on; default: offCreates port forward firewall rule to make application port in LAN reachable from selected BBMD interface.
Force gatewayoff | on; default: offAdds configured gateway IP address and port to BBMD packages sent.
Gateway addressip4; default: noneGateway IP address.
Gateway portinteger [1..65535]; default: noneGateway 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.
FieldValueDescription
IP addressipv4; default: noneIP addresses of the BBMDs in the network.
Portinteger [1..65535]; default: nonePort numbers on which the BBMDs listen for BACnet/IP messages.
Netmasknetmask; default: noneSubnet masks used by the BBMDs to determine the range of IP addresses within a subnet.
Actions-interactive button; default: deleteDeletes BDT configuration.

BIP Configuration

Communications in BACnet over IP (BIP) rely upon the protocol rules of IP and Ethernet.
FieldValueDescription
Network IDinteger [1..65535]; default: 1Unique identifier for the BACnet/IP subnet within the entire BACnet internetwork.
Portinteger [1..65535]; default: 47808This specifies the port number used by BACnet/IP devices for communication.
Deviceinterface; default: br-lanSelect the network device to be used for BACnet/IP communication.
Actions-interactive button; default: deleteDeletes 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.
FieldValueDescription
Network IDinteger [1..65535]; default: 2Unique identifier for the BACnet MSTP network.
MSTP MACinteger [0..127]; default: 13Router MSTP MAC address.
MSTP MAC maxinteger [1..127]; default: 127Maximum client address in the MSTP network.
Baud rate300 | 600 | 1200 | 2400 | 4800 | 9600 | 19200 | 38400 | 57600 | 115200 | 230400; default: 38400Serial data transmission rate (in bits per second).
ParityEven | Odd | Mark | Space | None; default: NoneIn 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 bits5 | 6 | 7 | 8; default: 8Number of data bits for each character.
Stop bits1 | 2; default: 1Stop 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..
