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 “I/O Modules” included in the description
concerning the process image of the corresponding coupler/controller.
