Patent ID: 7271752

Claim:
Arrangement comprising an interface component and connection points for field devices, wherein: the interface component includes an analog-to-digital converter, a digital-to-analog converter, a power source and a combinational circuit, through which, as required, the analog-to-digital converter, the digital-to-analog converter or the power source are each able to be automatically connected to connection points of the interface component; the interface component is able to be connected via a microcomputer to a digital data bus of a control and/or regulation device and a connection point for a field device containing a terminal, able to be configured via the interface component for the field device as an input and/or as an output, for bidirectional signals; the terminal is connected via a first ohmic resistor to a first connection point of the interface component and in that the terminal is connected via a second ohmic resistor to a second connection point of the interface component; and the first connection point is able to be connected via the combinational circuit to the input of the analog-to-digital converter and the second connection point via the combinational circuit to the power source, and the two ohmic resistors are not implemented in the interface component.
