What is a good way to determine if any signal in a bus changes value, when the signals in the bus have different data types? The Detect Change block requires that all input elements have the same type.

Hi Thomas,

As per my understanding one approach would be to create a bus object from the bus creator in your model that creates the bus using the function Simulink.Bus.createObject. Write a MATLAB function that looks to see if any of the bus elements match your specific signal name/type/size.

Hope this helps!
