S7 200 224 communication with WinCC 6.0

Hi,
I want to setup communication between S7200 (CPU 224) with WinCC 6.0 SP2 using the onboard port of the CPU.

1. Is this possible?
2. Do I need an OPC or some other software to do this?

I can ofcourse do this by adding a profibus card or ethernet card.

thanks,
Rahul

yes it is possible with opc server (pc accsess for example)

Thanks. Any idea where i can download it?
