Wireless field devices used in process control plants are configured over a wireless medium. In an embodiment, a host device discovers the presence of wireless field devices in the vicinity, and displays a list of discovered devices. The host device then enables a user to select a field device for configuration from the displayed list, and causes only the selected wireless field device to generate a human perceivable signal, thereby enabling a user to correlate a wireless field device listed in the display with the actual physical field device present in the vicinity. Upon confirmation from the user that the selected wireless field device is the device intended for configuration, the host device transmits the corresponding configuration parameters over the wireless medium, thus configuring the device.
