4.10.7.6 Topology Import-/Export

A Frame Application not aware of DTMs handling redundant slaves is not able to provide redundancy information within a FDT topology export file.

A Frame Application aware of DTMs handling redundant slaves can only add a DTMNode element at ChannelNodes if the appropriate DTM instance has not been added to topology by a IDtmRedundancy::OnAddedRedundantChild() event call. Instead the appropriate DTM element of the topology document should contain a BusInformation element containing the redundant address information.
