I want to have access (View + control) from an TP1200 Comfort, to a TP900. It means I would like to use the TP900 (with is phisical not reachable for the operator)  from the TP1200 (main panel for operator).
I have no idea this can be done with Sm@rtserver + sm@rtclient on HMI?

Anyone can help me out of this?
