ABSTRACT:
The invention relates to a peripheral component with high error protection for stored programmable controls. The invention relates particularly to an analog-input circuit with at least two channels substantially identical in design, for parallel signal input and/or output, which are parallel connected and/or parallel connectable in the region of the peripheral interface. Said analog-input circuit also comprises at least one data processing component (μP or μC) for testing the channels without any disruption of the data flows.
