Connectivity server redundancy problem in Advant master connect system.
I have installed two connectivity server CS1 and CS2 with AC450 connect.When I shutdown primary or secondary any one server then automatically OPC DA service(SG_Network11 both server going down) is going down.(Redundancy is not working properly).
When both CS1 & CS2 servers are up then all services are fine.
Could you please suggest what will be the problem for this redundancy failure.
Configuration checked:Redundancy server configured through SCC, RTA board is running, RTA board setting checked.
Is there anything I missed to cross check which is related to redundancy?

The MB300 OPC DA and AE services will abort, restart and remain in "Synchronizing" state if there are no other reachable nodes. This ensures no clients will stay with an isolated connectivity server.
There is no distinction between controller or PU410 in this regard. Two PU410 make good company but offer little (nothing) to subscribe to.
If this description fits your problem, just add one more node, preferably a controller to the MB300 control network.
