Component:Simulink | Category:Model error
I tried to debug the program step by step, but the Error appears just randomly.
Can you may help me?
Note: I updated the model, so it's working the way it should. I uncommented a few things, this version of the model is running, but as soon as you uncomment one single state more it fails.
My first thought was the datatyp of "H_counter" because I need this one to go below zero, so I changed it to int 32.
But this is not working.
BTW this is the Error output in Workspace:
if true
Stateflow internal exception: lasterrId = [Stateflow:Assertion], lasterrMsg =
[aFcnToAdd->isNamed()], thrown at
b:\matlab\toolbox\stateflow\src\stateflow\cdr\prs_eml_action_lang.cpp:224% code
end

Hi @David Vincon,
This assertion error is mostly due to all the state names being commented in the stateflow chart. Uncommenting them should resolve the error.
Also, 'MCON Check' will be an invalid state name after uncommenting since state names cannot contain embedded spaces - https://www.mathworks.com/help/stateflow/ug/rules-for-naming-stateflow-objects.html
Make sure to rename it to something like "MCON_Check".
Cheers!
