The idea is that we can have data-driven and event-driven ports to get events.
The (buffered) date driven get all events and the FSM reads them every update
But in case of eg. an emergency stop (kill switch), you don't want to wait till the next update, but take immediate action
(that's why we have the event driven port)

that is no problem
I'll use this
