IP router

Hello guys,

As I don't have much experience yet, I would hope if you can help me a bit.
I am trying to add an IP router, Jung IPR200REG to be precise. ETS can't download the router's application. It gives me the following error - "an error occurred accessing the bus"?

Physical address was easily to download, but the app failes every time.

I'm sure it is another newbie question and I still lack the knowledge to solve it.
I wonder if it is wrong wiring?

Kind regards

Angel
