Synopsis

  • UDP port 47810 is used by BACnet/IP as an alternate port, specifically 0xBAC2 (“BAC2”) within the BACnet/IP range 47808–47823 (0xBAC0–0xBACF).
  • Real-world systems that may listen on 47810 include Tridium Niagara (JACE/Station) BACnet drivers when configured for non-default ports, Johnson Controls Metasys BACnet/IP controllers, Siemens Desigo/PXC BACnet/IP controllers, and Schneider Electric EcoStruxure Building Operation servers/field devices.
  • BACnet BBMDs and routers such as Contemporary Controls BASrouter and Loytec L‑IP can be set to forward BACnet/IP traffic on 47810.
  • BACnet tools like YABE (Yet Another BACnet Explorer) and vendor commissioning software can scan and communicate on 47810 for alternate-port BACnet networks.
  • Internet scans (e.g., Shodan/Censys) regularly find BACnet/IP services on 47810 alongside the default 47808.
  • Security note: Exposed BACnet/IP (including 47810) has been abused for unauthenticated enumeration and, in some cases, write access to building automation points, enabling tampering with HVAC/lighting systems.
