BACnet; BACnet stack initialization failed. Unable to bind <IP-address>:<port>.

The BACnet driver is not able to bind to the given IP address and UDP port.


(1) The IP address matches a local network interface but the UDP port is taken by another application.

(2) The IP address does not match a local network interface.


(1) Open a cmd shell with elevated privileges (administrator). Run netstat -a -b -p udp and locate the IP address and port from the error message. This will give information about the application that is bound to that port. Terminate that application and restart the BMS Server.

(2) Provide the IP address of a local network interface in BMS Studio / BACnet / Driver configuration / BACnet IP Address.
