MATLAB Arduino Uno Simulink doesn't have option for Connected IO Mode

Hello;
I'm trying to use Simulink to get input from Beckhoff TwinCAT (reading an EtherCAT sensor) and then output it to an Arduino as a set of PWM waves (to control some coil currents). To do this, I'm trying to link the TwinCAT integration to the Simulink Support Package for Arduino Hardware on MATLAB R2021a on a laptop running MATLAB R2021a; however, I don't see the option to switch the mode to Connected IO in the top Hardware bar. I have tried enabling Connected IO in the hardware settings for the Arduino Uno on Simulink, but the option is still not showing up.
Is there something else I am missing?

For reference, here's what my top bar looks like. There should be a MODE area between HARDWARE BOARD and PREPARE, but there isn't.

Hi Nadeem,
I understand that you are trying to use “Normal Mode Simulation using Connected I/O” with an Arduino Uno board but unable to find the “Mode” section in the “Hardware” tab. Enabling the “Connected I/O” option in “Target hardware resources” section is the prescribed step according to the documentation of MATLAB R2021a.

The “Mode” section in the “Hardware” tab appears to be introduced in MATLAB R2021b and hence is not present when you are trying to enable “Connected I/O”.

Hope this helps resolve your query!
