you can try using jtag connector. Most pcb boards have one to test the board and to debug applications.

Re: Wincc professional v15.1(tia) and plc1200 (simulation)

Did you enable the PUT and GET in S7-1200?
If not, try to enable ir and test.

Go to the properties of the CPU -> protection and here you can enable the possibility to use PUT and GET instructions from another partner.
