1. A method for processing, in a central evaluating facility, analog output signals from a plurality of decentralized transducers, comprising the steps of:

  • generating a timing pattern at a decentralized location corresponding to the decentralized transducers in accordance with data-refresh intervals;

    sampling an analog output of each decentralized transducer in accordance with said timing pattern to obtain a sampled value;

    transmitting said sampled value of said analog output of each decentralized transducer directly to said central evaluating facility in the form of a data stream of successive digitized sampled values; and

    producing data sets at the central evaluating facility which contain one digitized sampled value from each data stream, said data sets being produced by the substeps of;

    generating latch commands at the central evaluating facility at intervals that are at least as great as the maximum data-refresh interval; and

    acquiring, after each latch command, the digitized sampled value of each data stream that is present, or if not present, the next arriving sampled value of each data stream.
