Fail-safe bus system for a process system

A method for connecting a field device () to an operating unit (), and a field device () 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 () by the operating unit () and that a response signal is generated by the field device () as a reaction to the query signal, in that the field device () 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.
