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.
