Variant control for variant subsystems with mask parameters?

Hello everybody,

I'm currently working a lot with referenced and variant subsystems and I'm wondering whether you could set the block mask parameters to control the variants.

I want a similar behavior as in the simulink PID(s)-block where you can choose the controller type via drop-down menus in the block mask. I don't see any possibility yet, to use other variables then the ones from the base workspace.

Any advice would be appreciated.

I think a good description can be found here: http://blogs.mathworks.com/seth/2008/08/13/dynamic-mask-dialogs/

In the Variant Subsystem > Subsystem Parameters, there is a check box for "Override variant conditions and use the following variant"

Check this box and select which variant you would like to use. This will do exactly what you are asking for.

Hi Nathan,

thanks for your answer. I know this function, but my model users want to change the variants by double-clicking on the block and changing a mask parameter.

Before that, we had configurable subsystems and even right mouseclick -->block choice --> var a or b was not, what they wanted. Everything shall be in one single mask. :-/

My ideas (but don't know, how it works):

- use referenced/variant Subsystems

- use variant control parameter and no override

A: Write mask parameters automatically to Workspace

B: Access mask parameter variables from the reference model block.

I see. So, you can create a mask and make a parameter for variant choice. You can then use the Dialog Callback in the mask to set the following property of the variant model block: OverrideUsingVariant
