Stateflow

Imported Data

Similarly, you might want to access a data object that is externally defined outside the Stateflow diagram, its Stateflow machine, and its Simulink model. If you define the data's scope as Imported, the data can be accessed anywhere within the hierarchy of the Stateflow machine (including any offspring of the machine). An imported data object's parent is external. However, the data object needs an adoptive parent to resolve symbols for code generation. An imported data object's adoptive parent must be the Stateflow machine, because the machine has the highest level in the Stateflow hierarchy and can interface to external sources. It is the responsibility of the external source to make the imported data object available (in the manner appropriate to the source).

If the external source for the data is another Stateflow machine, that machine must define the same data object as Exported. Stateflow generates the appropriate import and export data code for both machines.

Imported Data Example

This example shows the format required to retrieve imported data from an external code source (custom code).
