Stateflow

Outputting Data to Simulink

These tasks describe how to add and define the necessary fields for a data output to Simulink:

• Add a data object parented by the chart
• Choose Output to Simulink as the Scope
• Specify data attributes
• Apply and save the changes

Add a Data Object Parented by the Chart

These steps describe how to add a data object:

1. Choose Explore from the graphics editor Tools menu to invoke the Explorer.
2. Select the chart that you want to output data.
3. Choose Data from the Explorer Add menu. The Data dialog box is displayed.
4. Enter a name in the Name field.

Choose Output to Simulink as the Scope

Once you have chosen the chart as the parent, the choice of valid scopes includes Local, Input from Simulink, or Output to Simulink.

Choose Output to Simulink as the Scope of the data.

When you define a data object to be an Output to Simulink, a Simulink output port is added to the Stateflow block. Output data objects from the Stateflow block to the Simulink model are scalar.

Specify Data Attributes

If you want to change the defaults, you can specify data Units, Type, Initial, Minimum, and Maximum values.

Note    If you want the output port corresponding to this output data item to emit data of type other than double, you must select the chart's strong data typing option. See Defining Input Data and Specifying Chart Properties for more information.

Apply the Changes

Click on the Apply button to save the properties. Click on the OK button to save the properties and close the dialog box.
