Modbus Driver not switching between adapters

Modbus Driver not switching between adapters

Hi Support team
I'm using Zenon Energy 7.5 and communicating with IEDs using Zenon 61850 Driver through redundant fiber switches (L2 & L1)
Also I'm monitoring the switches alarms and port status using Modbus Driver in Zenon.
My Srvr (windows 7 Pro) has 2 network Adapters each adapter is connected to differen switch from L2 (lvl 2 switches) and each L2 switch is connected to different L1 (lvl 1) switch and at last the L1 switches are connected together creating a loop between all switches.
each IED has 2 redundant Fiber connection with the Two L1 switches).
When I disconnect the adapter (the active one) from the srvr:
1. Zenon 61850 driver is not inturupted and the IEDs signals are still valid on runtime.
2. Zenon modbus driver stops communicating with the Modbus slaves (the switches) although I still can ping all of them because of the loop connection.
My observed problem is that 61850 Driver is switching between the Srvr adapters or actually polling from both all the time.
But the modbus driver is polling only from one adapter and when I pull out the rj45 cable from that adapter or the L2 switch that is connected with that adapter fails off, Zenon Modbus driver is not switching to the srvr second network adapter.
Kindly need suport if there is possible update for zenon modbus driver or aditional configuration is needed in Zenon
Best Regards
