How to send back a continuously updating constant to workspace from Simulink ?

I have a analog read block to read the value of a potentiometer (using arduino). I want to save that value to my workspace in a constant so that i could later use it . I have tried it using ' To Workspace' and 'Simout' blocks , the problem is that the value is stored when the session of the simulink ends , which is clearly what i donot want . I want the constant to update continuously.

Any advice would be appreciated.

Could you explain more about how you plan to use the saved constant simultaneously as the model is running. Is there a MATLAB file that you are running in parallel?

Please see Access Block Data During Simulation for the recommended technique to access signal data during a simulation.
