Tushar, Thank you very much. Yes, I guess all the routers are connected to the same MessageBuffer and each router represents a logic bus. I think the controller does not listen to all the buses according to a particular order. Even if I connect a router before the controller, the router might not listen to all the buses according to a particular order. I thought the simple network's router arbitrates/allocates everything following the same round robin, but maybe that's not the case...
Thanks for your suggestion. I will look at the simple router first and then check the event queue if necessary.
