I am using Matlab R2015b.

When I create a non-virtual bus using Bus Creator, input signals (with signal names same as bus element name) to bus creator must be in order defined in Simulink.Bus object. If order is not followed then simulink throws error.

Buses are generally equivalent to structure in C. So it should be possible to refer the bus elements with names only provided that signal names are same as element name.

But why its depend on sequence of elements defined in Simulink.Bus object ??

I've got the same question.

In addition, is there a way to assemble a non-virtual bus without beeing forced to respect the order of the elements in bus object?

Thank you very much.

That seems to be a good solution.

For the default bus signal, you can use a constant block with a value of Simulink.Bus.createMATLABStruct('BUS_OBJ_NAME') and a data type of Bus: BUS_OBJ_NAME. Then feed this into the Bus Assignment block without needing to use a Bus Creator block.
