WIRELESS FIELD DEVICES HAVING EMBEDDED DEVICE DESCRIPTION DATA

A method of automatically providing a device description (DD) file for a wireless field device wirelessly coupled at least in part to a wireless device manager (WDM) that is coupled to a process controller in a process control network of an industrial processing facility (IPF). The wireless field device is provided with a sensor or an actuator, a controller, a transceiver and antenna, and with the DD file embedded in its memory. Responsive to a triggering event, the WDM automatically sends a read request to the wireless field device for reading the DD file. Responsive to the read request, the wireless field device transmits DD data for the DD file to the WDM wirelessly across at least a portion of a path to the WDM. The WDM receives and uploads the DD file.
