    摘要: In a method or device for powering a field device for a processing plant, the field device is driven by a process signal of an electrical power supply so that an electronic unit connected to the power supply outputs a process control signal. A required power level of the electronic unit is determined for outputting the control signal. A portion of an electrical power of the power supply exceeding the required power level is stored.

    摘要: An input circuit for a field device for communication with bidirectional signals superposed on an analog signal, the input circuit being part of a current loop, supplies the field device with energy and simultaneously carries an analog current signal for prescribing a reference value. The field device is connected to an actuator that is suitable for achieving the reference value, and the input circuit has a voltage limiter, a shunt resistor and an inductance connected in series between its input and output. The input signal of an analog-to-digital converter can be taken at the shunt resistor. The voltage limiter is connected in parallel with a voltage regulator. The inductance is coupled via a capacitance to a reception unit and/or to a transmission unit for digital signals.

    摘要: In a method for communicating electrical positioning information of an actuator-positioned final control element such as a valve element, the positioning information resulting from continually sensing the position of the final control element, a binary signal is formed or received signalling a condition 0 (zero) when the final control element has attained a predefined position and a condition 1 (one) when the final control element has not attained the predefined position or the predefined position range. For forming a positioning signal, the corresponding signal condition of the binary signal and the associated continually sensed positioning information are combined such that the corresponding signal condition of the binary signal or the positioning information or both can be optionally invoked from the positioning signal.
