Abstract: A computer program product, field device, higher-order control unit, automation system and method for operating a field device which includes a plurality of components, wherein the field device is supplied with electrical input power via an isolating amplifier, where the isolating amplifier is activated and an available electrical input power ascertained, a plurality of operating configurations having different compilation of functions of the field device is created respectively, one power requirement each is ascertained for each of the operating configurations in each case of at least one predefinable operating profile, deployable operating configurations and their associated operating profile, in which the respective power requirement is lower than the available electrical input power are ascertained and an associated function profile respectively is ascertained, and where the ascertained function profiles of the field device ascertained are provided for selection.

Abstract: Operating method for a valve system, computer program product, controller, valve actuator, valve system and simulation program product, where a valve is moveable between first and second end positions, the valve system is initially made available in an active operating state, the first end position of the valve is approached by actuating the valve actuator and the first end position is detected as a first absolute position of an actuating shaft and, alternatively or additionally, the second end position of the valve is approached by actuating the valve actuator and the second end position is detected as a second absolute position of the actuating shaft, a design of the valve is identified via the first and/or second absolute position of the actuating shaft by an algorithm, and the identified design of the valve is transmitted by the valve actuating apparatus to a controller and/or is parameterized via the identified design.
