摘要： The invention relates to a method for operating a control system of an industrial process, the control system having at least one control loop comprising a sensor (200), a control device (300) and an actuator (400), the actuator being connected to the sensor (200) via the industrial process (100). To detect faults in the control loop, it is proposed to inject (51, 52) a predefined test signal at an arbitrary point of the control loop, and to monitor (61 to 63) the response of the control loop as a function of the test signal at a separation of at least one control-loop element.

摘要： An arrangement is described for supplying electrical power to a field device (10) with a housing (11) for monitoring a technical process in a process installation, without the use of wires, which field device (10) has a wire-free communication interface (5). The field device (10) has at least one field device face (11a) facing the process and at least one field device face (11b, c, d) facing away from the process, and is equipped with a thermoelectric transducer (14) which has a transducer face (14b) facing the process and a transducer face (14c) facing away from the process. The heat flow in the field device between the field device face (11a) facing the process and the field device face (11b, c, d) facing away from the process is converted into electrical energy by the thermoelectric transducer (14), and this conversion process may be bidirectional.
