A method for connecting a field device (1) to an operating unit (2), and a field device (1) for use therewith, via which a connection between a field device and an operating unit can be implemented when the field device is mounted at a location that is difficult to access is achieved in that a query signal is transmitted to the field device (1) by the operating unit (2) and that a response signal is generated by the field device (1) as a reaction to the query signal, in that the field device (1) generates a blinking display and/or a change in color of the display and/or an acoustic signal and/or a change in an acoustic signal.
