Tja,

2.Since you can establish a connection between your PG and the PLC your cable and pc-adapter are working properly.

3.Yes you can, are you running WinCCFlexible integrated to Step7, make sure you have the correct transfer settings in STEP7, under "SET PG/PC INTERFACE".
Under this menu you have another good function called diagnostics, connect to your panel and click "Read". Now the adress of the panel should appear, marked w an arrow.
If this isn't working I think you have wrong communication settings in the panel, go in under settings in the panel and make sure you enabled the DP interface and settled the correct adress.
