Process Image

4 Process Image
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.
