Abstract
A device for determining a signal running time between a position measuring system and a processing unit. The device includes first and second position signal generators that generate position signals regarding relative chronological position of a first running time measuring signal with respect to first and second data words. A first transmitter that transmits the first running time measuring signal and the first position signal to the position measuring system at the end of transmission of the first data word to the position measuring system. A second transmitter that transmits a second running time measuring signal and the second position signal to the processing unit after the end of transmission of the second data word. A timer that ascertains a length of time between transmission of the first running time measuring signal and reception of the second running time measuring signal by the processing unit and a signal running time generator that determines a signal running time from the length of time.
