Using

set_param('model', 'SimulationMode', 'external')

set_param('model', 'SimulationCommand', 'Start')

a simulation with Arduino I/O can be run from an M-script.

Can the same be done in the simpler "Connected IO" mode?

I was searching a SimulationMode like 'connected_io', but it doesn't seem to exist.

Or does it?

Hi Manfred, I understand you are trying to call "Connected IO" mode for simulation programmatically, you can use the following code to do that, it may not show any visible changes when MATLAB opens up but it should run if the Simulink Model is run programmatically too.

set_param('model', 'SimulationMode', 'external')

set_param('model', 'SimulationCommand', 'Start')

set_param('model','ConnectedIO','on')

Thank you Aman.

set_param('model','ConnectedIO','on')

is what I needed. After setting this parameter my simulation could be run simply with the 'sim' command.

However, with

set_param('model', 'SimulationMode', 'external')

set_param('model', 'SimulationCommand', 'Start')

Simulink always uses code generation and runs the model in the "Monitor&Tune" mode, not in "Connected IO" mode. The additional "set_param('model','ConnectedIO','on')" then seems to have no effect.

In short:

set_param('model', 'SimulationMode', 'normal')

set_param('model','ConnectedIO','on')

sim('model')

does the job.
