Full quote The transition from the initial pseudostate to StandBy has a relative TimeEvent with an expression indicating that the transition fires 5 seconds after the initial pseudostate is entered. Next snippet The transition from StandBy to On has a ChangeEvent with an expression indicating that the transition is triggered when u.sigsp [ERROR] is equal to 1 (this is a signal as in signal flow simulation, not as in SysML). Related snippets Computer has ports u and y of type RealInSignalElement [ERROR:TYPO] and RealOutSignalElement [ERROR:TYPO] from the signal flow library (see Subclause 11.2.1), respectively. The state machine has one initial pseudostate, and two states StandBy and On. Related snippets (backlinks) The transition from StandBy to On has a ChangeEvent with an expression indicating that the transition is triggered when u.sigsp [ERROR] is equal to 1 (this is a signal as in signal flow simulation, not as in SysML). The transition from On to StandBy has a ChangeEvent with an expression indicating that the transition is triggered when u.sigsp [ERROR] is equal to 0. When the computer is in StandBy, y.sigsp [ERROR] is set to 8, and when the computer is On, y.sigsp [ERROR] is set to 3. Visit also Visit also (backlinks) Flags
