Control chart execution with the duration operator





duration(C) returns the number of seconds after the conditional expression, C, becomes true. The duration operator is reset if the conditional expression becomes false. If the duration operator is used within a state, it is reset when the state that contains it is entered. If the duration operator is used on a transition, it is reset when the source state for that transition is entered.

The transition occurs when the value of x has been greater than or equal to 0 for longer than 0.1 seconds.

[duration(x >= 0) > 0.1]
