Why do I receive error when I run a simulation on Simulink with a PIL block for Arduino Mega and gives that there is no connection with the Arduino board?

I tried to run the example "Arduino_PIL_Block"(attached). I created the PIL block and located in the model as shown:

When I started the simulation in "Normal" mode I get the following error:

• Noting that I have no problem when I remove the PIL block and run the model in external mode or deploy the controller to the board after cancelling PIL creation.
• My MATLAB is 2017b 64bit and my OS is Windows 7 64bit.

I have the same problem. Do you know if this example works with Arduino Uno Board?

Thanks in advance

Arduino Due works but Mega does not work to me!! Unf, MATLAB does not answer!
