4.10.7.5 Scan and Redundant Slaves

Fieldbus scan provides for each address of a redundant slave one entry, a redundant slave can not be detected.

In scenario 1 mapping of redundant addresses to one instance is only possible for a DTM itself, in scenario 2 mapping can only be done based on project knowledge. Typically a scan is not executed on a redundant system.
