Mapping of process data in the process image of fieldbus systems
The representation of the process data of some I/O modules or their variants in the
process image depends on the fieldbus coupler/controller used. Please take this
information from the section "Fieldbus Specific Design of the Process Data"
included in the description concerning the process image of the corresponding
fieldbus coupler/controller.
