How to export FMU with bus signals as ports?

Hello Mathworks community,

I want to export an FMU with bus signals as in-and output ports.

The green subsystem contains two bus selectors.

The inside of the subsystem looks like that:

If I try to export it to an FMU, Matlab drops an error message. It is saying that there is not bus signal connected to to "Bus Selector1".

Can I fix the problem by using "InBus" and "OutBus" connections?

Best regards

Nils

Hi Nils, could you please check if you specify datatype in the inports block and compile the model?
