Who-Has-Feature

The Who-Has feature allows you to search for specific objects by object name on a BACnet network. If you need to know the network locations and Object IDs of one or more objects in other BACnet devices, you can send a Who-Has broadcast request over the network specifying an object name.

Devices that contain an object matching the request respond with an I-Have to this request and are then listed in the Listening for I-Haves section of the Who-Has dialog box. Object information is listed by Adapter Name, Device Instance, Object ID, and Object Name. The object can contain wildcards such as AI*, *A*, or *A.
