Switch between subsystems using a trigger

Hey guys I have a question concerning switching between subsystems. I have a Simulink model and want to switch between two different states.

The output of the If block shall NOT be the input of the subsystems but more a trigger: If u1 > x then go on by calculating with the first subsystem else take the other one with another calculation. Do you have an idea how it will work?

Thank you in advance

David

use if action subsystems instead of normal subsystem and connect the output of if/else block to the function call port of the if action subsystem
