Transition condition of Stateflow as Parameter

Hello Everyone. Is it possible to set a transition condition of Stateflow as something like "mask-parameter" or variables? Many thanks!

[Prasanth Sunkara]

Can you please provide more information/code?

[Yuntao Zhang]

Sorry that I don't have any codes. It's just a general question:

• If I set parameter "a" as mask-parameter, I can change it without "look under mask" (for example set a=1 for one project, and a=2 for other)
• Analog: Is it possible to set Stateflow Transition Condition as something similar to mask-parameter without go inside the Statechart? (for example set transistion condition "[b>0]" for one project, and "[b>2]" for other )

Thanks a lot for answers

Yes, this approach does work.

If you create data in Stateflow, you can set its "Scope" to "Parameter".

When you update the model, Simulink will search for the variable in the following order:

• Mask workspace
• Model workspace
• Base workspace

... so, if you create a mask around the Stateflow chart and define a parameter b in the mask, you're all set.
