PEs are connected through streams, and events flow from PE to PE through those streams. So when creating the PE graph, just make sure you have (down)streams created in PE prototypes and that you use them for building the PE graph.

I would like to know how can one implement PEs in a way, one PE outputs events that are inputs for other PEs
Hope this helps,
