Abstract

The present invention is directed to a sensor for use in automation technology and a method for transferring configuration data from an external computer to a sensor. The sensor includes: a sensor element for measuring a physical variable; a control/evaluation unit for controlling the sensor element, for processing a measuring signal from the sensor element, and for outputting an output signal to a computer interface; wherein the control/evaluation unit includes a memory for storing at least configuration data and program data, the control/evaluation unit cooperating, in an operating mode, with the computer interface for connecting the sensor to a peripheral unit, and wherein the sensor is supplied with electrical energy by the peripheral unit, in the operating mode; wherein the computer interface is adapted for use in a configuring mode for direct connection of the sensor to an external computer; the sensor is supplied with electrical energy by the external computer via the computer interface, in the configuring mode; and the computer interface is adapted to transfer, in the configuring mode, configuration data differentially between the sensor and the external computer through two wires of a data line at a bandwidth of more than 1 MBit/s.
