Use parameters from one module to another

A question by @Fredrik_Svensson:

I have been investigating if you could use parameters from one module to another, but I am not able to set parameters from Module 1 to Module 2 or at least I cant see the result when I am doing that. Is it any way to see the result when you are sending parameters from one module to another?

@Fredrik_Svensson Can you please elaborate on that - how exactly you do it? What is the expected result?
