Which data could be forced or modified in s7-1200?

When you have TIA Portal open, press the F1 key and search for those same questions and you may find answers that answer your questions.  You may find them faster than waiting for someone else to answer them as well.

I find I can force outputs, and modify everything, but physical inputs need a simulation table.  F1-Help will help describe those concepts in more detail if needed.

There are also many online tutorials and videos and webinars available which show these types of tasks.
