The BACnet implementation from PcVue version 11.2 onwards uses different technology to which this article is not applicable.
Summary:

The BACnet protocol, as with other protocols, uses a specific port (47808 by default) to send and receive messages. If the port is already used by another application, process or service, there will be a conflict.
Details:

In there is a BACnet port conflict an error message will appear in BDSAdmin screen.

This message indicates that this port is already in use. To check which application is using the BACnet port, you can run the following DOS command.

netstat -a -o -p udp.

This command will display which UDP ports are used and the corresponding process ID’s.

Once you have found the Process ID using port 47808 (or the one you configured in BDSAdmin) you can find the corresponding application using the Task Manager.
