Sending a Who-Has

  • You want to send a broadcast to the BACnet network to view which devices have the object you are searching for.
  1. From the system tree in the left pane, select a BACnet Network.
  1. From the Services menu, click Send Who-Has.
  • The Who-Has dialog box displays.
  1. Enter a unique object name. Object names must be unique within each BACnet device residing on the BACnet network since you may find more than one object with the same name on the network. You can use wildcards to help you select a unique name.
  1. Click Send Who-Has.
  • A Who-Has broadcast request is sent over the BACnet network specifying an Object Name. Any devices that contain an object matching the request respond with an I-Have, and the Listening for I-Haves list is populated with responding devices.
