Does DeltaV serial card supports ring topology, without use of any additional drivers from Mynah? The end user wants to connect 3 devices to deltav serial card in a ring. Is it possible?
Thanks.

Hi,
personally I have never seen that you could connect serial communication in a ring.
You can connect RS-485 as multidrop configuration.
If you want a "redundant" ring you have to use additional hardware to do that for example:
