UDP 1628
Synopsis
- UDP port 1628 is assigned to LonTalk “normal” traffic for LonWorks/LON/IP (ISO/IEC 14908 over IP).
- It is used by building automation and control systems to tunnel LonWorks messages across IP networks.
- Real-world examples include Echelon i.LON SmartServer gateways and routers using LON/IP on UDP 1628.
- Loytec L‑IP routers and NIC-USB/IP interfaces also use UDP 1628 for LonWorks/IP communication.
- Tridium Niagara (JACE) controllers speaking LonWorks/IP rely on UDP 1628 when connected via LON/IP routers.
- Major BMS platforms such as Honeywell EBI, Johnson Controls Metasys, Schneider Electric (TAC Vista/StruxureWare), and Siemens Desigo use UDP 1628 when integrating LonWorks networks over IP.
- Devices often pair this with UDP 1629 for “urgent” LonTalk traffic.
