Hey all!!
I am trying to simulate railway traffic signal having 2 platforms. I am encountering an error which I am not able to understand.

It looks like you are attempting to access P1 and P2 in multiple state machines. You have defined P1 and P2 as global variables in your statecharts. YOu need to add a global Data Store Memory in the Simulink model for P1 and P2 that the statecharts can access.
Thanks.
Mark.

For UI, easiest approach is to use Simulink Dashboard blocks:
if you need more capability that is available in Dashboard blockset, you can create your own MATLAB UI using Application Designer, but this is more work. https://www.mathworks.com/help/vnt/ug/developing-an-app-designer-app-for-a-simulink-model-using-can.html
