Abstract:
In a method for the function checking of a process-automation field device, a radio signal is transmitted from a transmitting unit to the field device, and, with the help of this radio signal, a query of the device status is triggered in the field device. Depending on the result of the query of the device status, a corresponding, perceivable signal is produced.
