Transitions Priorities
This text addresses the ordered functioning of multiple transitions in a Hierarchical State Machine using
QFIRE Studio
.Introduction
In a Hierarchical State Machine, it is possible to have multiple state working in different arrangements, therefore, it is necessary to use several transitions as shown by Figure 1
Figure 1 - Hierarchical State Machine with 2 transitions
There is de same diagram shown by Figure 2 in the Finite State 2 and 3 of Figure 1.
Figure 2 - Generical Diagram
Both transitions have the following diagram shown in Figure 3.
Figure 3 - Transition Diagram
Due to the diagram, both transitions can be triggered as soon as the simulation starts. Because of this, the priority of the transitions is validated; that is, since there is Transition 1 and Transition 2, Transition 1 will always be evaluated before Transition 2. The result of this can be observed in Figures 4 and 5.
Figure 4 - Finite State 2 Scope
Figure 5 - Finite State 3 Scope
As can be seen, only Finite State 2 is executed because Transition 1 is the prioritized transition.
