Abstract
A field device for process instrumentation, in particular a measuring transducer, comprising an analogue output to which a two-wire line is connectable for transmitting an analogue output signal. The output circuit contains a controller with an actuator connected downstream for the analogue output signal. A monitoring unit monitors whether an actuating signal remains within a predeterminable value range to monitor the output circuit for correctly setting the loop current. If the actuating signal is outside the value range, an indicator signal is output to a computing unit so that suitable measures can be introduced in response to an error state that has thus been identified.
