Mapping of process data in the process image of fieldbus systems
The representation of the I/O modules' process data in the process image depends
on the fieldbus coupler/controller used. Please take this information as well as the
particular design of the respective control/status bytes from the section "Fieldbus
Specific Design of the Process Data" included in the description concerning the
process image of the fieldbus coupler/controller used.

Standard Data Format

For the 750-469 module and its variations with standard data format, the
temperature values of the sensors are represented with a resolution of 1 digit per
0.1 °C within a word (16 bits). Thus, 0 °C corresponds to the numeric value
0x0000 and 100 °C to 0x03E8 (dec. 1000).
