The BACnet connector correct URL format is: bacnet://{host}/{deviceId}?dnet={BACnet network no}&dadr={BACnet address}&hops={hop count} where:

  • host: is the ip and port of the bacnet device

  • deviceId: is the device instance of the bacnet device

  • dnet: is the network number of the bacnet device

  • dadr: is the mac address of the bacnet device

  • hops: is the hop count of the bacnet device (default is 255)


Example: bacnet://10.10.1.200:47810/1000?dnet=200&dadr=06&hops=255

For IP devices, its simple with just the host and deviceId. Example: bacnet://10.10.1.200/1000

If the user will input a correct HOST but will put the wrong device instance number in, then an "Unknown Object" error will be thrown at the connector level.

If the user will put the wrong network number/ host/ mac address in, then a "Socket timeout" error will be thrown at the connector level.
