Hi all,

I've two Rx7i redundant racks (RMX based redundancy) and two ENIU Rx3i based Remote IO racks. Both Remote IO Racks have the same HW configurations and common with common input signals on each DI cards.

One ENIU is connected with a single Controller (Primary/ Secondary) vis Ethernet. ENIUs don't have any common link to communicate with each other. Should I configure a single Target for both ENIUs or go with one target per ENIU.
