in Data Word
For the 750-469/000-200 and 750-469/000-206 variations, the temperature values
of the sensors are represented with a resolution of 1 digit per 0.125 °C within a
word (16 bits). Thus, 0 °C corresponds to the numeric value 0x0000 and 100 °C to
0x0320 (dec. 800). Diagnostic information is indicated in the 3 low bits.
