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. Source SysPhS-1.1
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. Source SysPhS-1.1
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). Source SysPhS-1.1
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. Source SysPhS-1.1
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. Source SysPhS-1.1
The following Modelica code corresponds to Figure 28. It has a type Force, which extends Real, and the unit symbol N assigned to it. Source SysPhS-1.1
Modelica data types can be subtyped to add a unit symbol. The interpretation of this symbol is not defined in Modelica. Source SysPhS-1.1
Figure 28 shows how a value type with units is defined in SysML, from the units library in Figure 20 [ERROR], Subclause 11.2.2 [ERROR]. It has a value type Force that specializes the Real value type and has newton as unit. The newton unit has a symbol N. Source SysPhS-1.1
