Author and Simulate Basic Colors Sequence Diagram with Enumerations

Define BasicColors.m Enumeration

Create an enumeration class called BasicColors and define Red(0), Yellow(1), and Blue(2) as the enumerated values.

classdef BasicColors < Simulink.IntEnumType
  enumeration
    Red(0)
    Yellow(1)
    Blue(2)
  end

Open Enumeration Example Model

Open the EnumExample.slx architecture model that contains a sequence diagram that implements the BasicColors enumeration.

model = systemcomposer.openModel("EnumExample");

Double-click the source component to inspect the Stateflow® Chart (Stateflow) block.

The output data port, data, is typed by the BasicColors enumeration in this state chart where the color changes from Red to Yellow as the model simulates.

Open Enumeration Sequence Diagram

Navigate to Modeling > Sequence Diagram to open the Architecture Views Gallery and access the EnumSequenceDiagram sequence diagram. Click Run to simulate the sequence diagram.

As the inEnum destination port inherits a value of 1 from the BasicColors enumeration, indicating a change from Red (0) to Yellow (1), the sequence diagram executes successfully.
