  • Publication number: 20040133373
    Abstract: The invention relates to a position measuring device (100), which supplies a multidigit code word (P) to a numeric control (300) via a serial interface (14). To determine the current functional state of the position measuring device (100) instantaneous values of analogue sampled signals (S6, S7) are also serially transmitted as multidigit amplitude-proportional code words (D6, D7). Said code words (D6, D7) are supplied to a diagnostic device (200), which displays a Lissajous figure (201) derived from said words, or independently performs an evaluation and generates warnings or alarms.
