How can i use Ethernet module with Quantum Hot Standby Configuration? I am using Ethernet module with IO Scanner. How will be IO Scanning Transfered standby controller in case on failure of primary? Have anyone used this configuration?
 
Ethernet communication is not a real Hot-Standby solution, not supported. Only Remote I/O is supported by Quantum as a real HSBY solution. However if your appication (IOscanned devices)can tolearte a couple milisecs of bump, then works ok. For Example slowly changed analogs.

Not entirely true. Redundant NOE modules are supported in a Quantum Hot Standby configuration. The IP addresses are offset by "1".

Using Ethernet IO connected to a NOE module in a HSBY configuration is definitely not recommended, and you will get a "bump". The only IO configuration supported by HSBY is Remote IO.

Do it right and make your life easier.
