S7-1200 PLC - MITSUBHISHI MELSEC Q SERIES

Hello,

pls for first we need to know (we know that you're new to this problematic) what your S7-1200 play role - Master or Slave. Due this selection you need have also suitable CM module. I recommend start study Profibus basics, also some topics can be helpful in Decentral Peripherie Conference. In my opinion hard to find exactly example to your situation, you can find very similar topics about other S7 HW Profibus connection which can be also helpful to you for understand principles. Don't hesitate ask next questions.

Update: some example which maybe can be helpful (link): S7-1200 to G120 Profibus Example

In other case you can download Step7 TIA Pro V14 SP1 manual and start study from page 2713 and 2794 for S7-1200 system, insert page value. This can be also good start point, then you can look to that my sugested example.
