Hello!

I'm looking for solution (with Simulink, Stateflow, Embeeded coder) to iteratively send the signals to communication channel.

For example, I have a bus (non-virtual) with contains different messages to be send:

InfSystem.warrningMsg.problem1

InfSystem.warrningMsg.problem2

InfSystem.errorMsg.problem1

etc

I can send only one message per time, so I need to processing it iteratively (for-loop like).

The actual implementation uses a MATLAB function to convert bus to cells vector manually (as in the example: https://nl.mathworks.com/help/simulink/ug/attach-bus-signals-to-matlab-function-blocks.html)

I'm wondering if there is an example for use only Simulink (with Stateflow) blocks.

Hey @Dimitri,

While not a complete solution, one suggestion on how to get a for loop iteration functionality in your model is to use the For Iterator block in Simulink. You can refer more about it in the documentation linked below:
