No communication of WinCC RT Advanced with S7-1200

Hello experts,

In TIA Portal V13, I have made a simple program (one input and one output) and a WinCC RT advanced PC station HMI (along with IE-general) having two buttons (set and reset input) to run it on my PC. When I go online in PLC and modify input, it affects output accordingly. But when I start runtime of HMI, it does not operate from HMI, there is no effect on output in logic.

I've checked everything and it's fine. In pic 1,  you can see network topology with established connection. In pic 2, I've defined connection in HMI tags...all events of button in HMI are ok... simple HMI screen... simple program.. 

Note: I've set my system's IP : 192.168.0.4
                                   PLC IP : 192.168.0.2  HMI STATION IP: 192.168.0.4

Kindly guide me how can I communicate PC-station based with PLC S7-1200. Thanks!

Regards

Jack

Hello Sir,

There is no PG/PC interface in control panel. How to get one?
