You should be able to communicate between the 2 using either an MPI connection or Profibus as long as there is a suitable cable between them. You need to set the screen to MPI/Profibus from the control panel of the HMI and make sure the baud rate is compatible with your network settings. Once that is done you should be able to download through WinCC Flex without any problems. The first download generally takes longer as more files are transferred but after that it takes seconds for any further updates you do.
On the first download you may also be asked to change the firmware revision of the screen if it doesn't match whatever version of WinCC Flex you have created your project in.

Yes you can. If there is nothing else on your network you can use the cable you have shown as long as the terminating switch is turned on at both ends. It should work on either the Profibus port or the MPI.
You have loaded the PLC program and the HMI program ?
And you did this with the PC Adapter USB connected to the PG Port on the 312 CPU ?
If that is the case, cable and connections should be OK.
Post a screenshot of the connection setup in WinCC Flexible.

I cannot see any configuration error.
It should not be necessary to download anything to the S7 PLC to allow the connection.
What is the message on the KTP that says that there is no connection ? What number ?
