Abstract
A method for operating a field device, and a field device that is operated according to the method, in which a measured value is generated, the measured value being assigned a current set point, a target current signal being issued depending on the current set point, wherein an actual current signal is fed back and the target current signal is compared to the actual current signal. To provide more exact comparison of signals a cross-correlation of the target current signal with the actual current signal is formed for comparison.
