Storing value in simulink

Is it possible to store a value in simulink? Let's say i have a sine wave and a ramp function, i want to store the value of the sine function at the exact moment the ramp function reaches the value 1

when the sine wave reaches back to the same value, i want an action to trigger each time the sine function reaches this value. Is this possible in simulink? If so how do i go about doing it?

For example, when the ramp function reaches the value of 1,

the value of the sine function is -0.05

so whenever the sine function reaches this value i want to trigger a switch block to perform a certain action.

We can store values in Simulink. But, Not at runtime. Once a simulation is done we can store the values of that simulation in workspace and use them for next simulation.

Refer to this link for better understanding:

But in your case, you can do like this:

Use compare to constant and switch block to store the value of sine, at point where value of ramp is equal to specific value, in your case 1. Then you can use compare and trigger the switch. You can refer to attachment I attach for better understanding.

See Triggered Subsystems: https://www.mathworks.com/help/simulink/ug/triggered-subsystems.html. This link shows an example of their usage: https://www.mathworks.com/help/simulink/slref/triggered-subsystems.html
