Hi everyone,

how you can see from the picture, the function "sim" starts working in the first block.

In the second block, the reference is costant.

In the third block I use again the function "sim". How can I restart this function? It keeps calculating even in the second block, I'd need a way to restart from the begginning or reset the function "sim" in the third block (as if called again for the first time)

thanks for the help

Hi,

It is my understanding that, in your model, “sim” function starts working in the first state, and even keeps calculating in the second state. You want to know how the function “sim” can be restarted from the beginning or can be reset in the third state.

For this you can bind the “sim” function to first state and second state separately. Bind to a state means the “sim” function resides inside the state. By doing this, the function is enabled when the state is entered and disabled when the state is exited. Hence in the third block the “sim” function will be called as if it is the first time.

To know how to bind a Simulink function to a state refer to below documentation:

Hope this helps!
