Hi all, I'm trying to design a stateflow chart and I've those requirements:

Move from state A to state B if incomming signal (T) from Simulink is up a threshold for at least 10 seconds (Time out expired).
if (T > threshold) but not for 10 sec THAN reset the timer and still in A
if next time that T > threshold , the timer restart from 0

I would design the chart with only two state (A and B) and describe the timer condition on transition link, but I don't found a solution. Any suggestion?

Thanks !!!

I am looking for the same solution. Is there a suggestion to solve this in only two states ?

1. Use counter as input which will increment continuously outside the state 2. Add transition from A to B : condition (T > threshold) && counter > 10 sec action : timer reset to 0
