Hello,
I want to create a subsystem that I can reuse in different scenarios (maybe as subsystem reference, not really important).
I would like to pass the signal to this subsystem as a virtual bus.
Inside the subsystem I use the in bus element to get the signals I need from the bus.
Now, since I use this subsystem in different models/configurations there are signals that sometimes are present and sometimes are not present inside the virtual bus, like in the example image below: signal3 is not present inside the bus and so simulink throws the error:
Selected signal ‘signal3’ in the Bus Element Inport block ‘untitledeee/Subsystem1/In Bus Element1’ cannot be found in the input bus signal.

I would like to use a default value when I recognize that the input is missing. In matlab functions you can easily do this with optional arguments (link: arguments – defaultValue).
My question is: there is a way to replicate the optional arguments of matlab functions inside a subsystem/reference subsystem/model reference?
There is some suggested workaround?Hello,
