Abstract
A method for transmitting signals from a position measuring arrangement to an evaluation unit, the method including transmitting position signals, reference pulses, and warning signals indicating a malfunction state from a position measuring arrangement for determining the position of two elements of a machine which are movable relative to each other, to an evaluation unit. The method further includes logically interconnecting the reference pulses with the position signals in such a way that, in a malfunction-free state, a valid status combination for outputting the reference pulses and an invalid status combination for outputting the reference pulses appear in each period. The method including transmitting warning signals indicating a malfunction state during the invalid status combination of the position signals and the reference pulses which, in the malfunction-free state, is invalid for outputting the reference pulses.
