How to export simulink data to workspace during simulation?

Question

I want to retrieve the data from simulink during simulation, and use serial network function to send these data to another program. Because I need to use an

Answer 1

During simulation Simulink stores logged data in an internal buffer and only writes the data to the Workspace when the simulation is paused or stopped. It sounds as if you really need to write an S-function (which will get signal values on a timestep-by-timestep basis) and communicate with Proteus that way.

Of course Simulink is a non-realtime simulator, so if you are talking about doing anything resembling real-time control then you are most likely taking the wrong approach altogether.
