BACnet Protocol

BACnet is a protocol suite for the building automation.

The connection is using IP and UDP.

During the startup of the connection the device identifier is requested online using an UDP broadcast.

If the network security settings are not allowing this the device id can be entered by hand.

Remote networks can be simply accessed over a BBMD device. BBMD stands for Bacnet Broadcast Multi Device.

BBMD mostly will be used during the connection configuration. It handles the broadcast for finding the BACnet devices in the remote network and returns the connection parameters accessing them.
