The information in this page is updated in accordance with firmware version RUT9M_R_00.07.04.3.
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 RUT956 devices.
Note: BACnet is additional software that can be installed from the Services → Package Manager page.
|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.|
Communications in BACnet over IP (BIP) rely upon the protocol rules of IP and Ethernet.
|BIP port||integer [1..65535]; default: 47808||BIP UDP port.|
Master - Slave Token Passing (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.
|MSTP MAC||integer [0..127]; default: 13||Router MSTP MAC address.|
|MSTP MAC max||integer [1..127]; default: 127||Maximum master 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.
|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..|
