    摘要: Field devices for measuring a pressure or a fill level are connected, by way of a cable connection or a radio connection, to stationary evaluation- and display devices. To provide flexible parameterization or flexible measured-value inquiry, a connection box for the wireless transmission of signals between the field device and the control device is stated, which connection box comprises an interface connection and a radio interface. For the purpose of transmitting the signals, the interface connection and the radio interface are coupled to each other so as to be able to communicate.

    摘要: A circuit arrangement for transmitting data between a field unit and a control device with a first data interface for being coupled to the control device and a second data interface for being coupled to the field unit. A galvanic isolator is situated between the data interface on the side of the control device and the data interface on the side of the field unit, wherein the first data interface and the second data interface are coupled in a communicating fashion by the galvanic isolator. The circuit arrangement furthermore features at least one data storage device, wherein the data storage device is either coupled to the first data interface or the second data interface. The data storage device is designed in such a way that data of at least the first or the second data interface can be recorded on demand by the data storage device.

    摘要: At least one physical layer parameter of a field bus signal is determined by a filling level measuring device, a pressure measuring device or a flow measuring device. Based on the at least one determined physical layer parameter, a status report is transmitted to an external device. No external diagnosis tool is necessary.

    摘要: A circuit arrangement for a field device includes an input, an output and a current-limiting element. The circuit arrangement is designed to transmit a useful signal along a useful-signal path from the input to the output. The input and the output are galvanically separated from each other. The current-limiting element is arranged outside the useful-signal path.
