Abstract: A field device that provides a field device that allows the simplest possible logging of relevant operational data. The field device has at least one data storage device (3) designed as an integral component of the field device and a control unit designed as an integral component of the field device (1). In this case, the control unit stores a data set in the data storage device (3) depending on a monitoring event.

Abstract: A method for generating an output signal and measuring arrangement for determining at least one measured variable use at least one sensor device (2) and at least one signal output (3) for outputting at least one output signal, wherein the output signal transmits information about the measured variable and/or a state of the measuring arrangement using at least one predetermined value of the current. The measuring arrangement ensures reliable outputting of an error signal indicating the presence of an erroneous state is achieved in that a first adjusting unit (4) and a second adjusting unit (5) are provided that set the value of the current of the output signal to a predetermined desired value. The first adjusting unit (4) sets a fixed current value and the second adjusting unit (5) sets a variable current value.
