Simulink and C++ program cosimulation

Hello, I have an application written in C++ (VC) which is event trigged program and I want to couple it with a plant model made in simulink. The challenge is that the C++ program should transmit an input to the plant (to simulink) and receive an output back in steady intervals (from simulink). Depending on the output the input can be modified by C++ program. Simulink and C++ program should work simultaneously and exchange data. Is it possible? Thanks in advance for any answers.

Yes, you can create a C++ S-function block and use your C++ as if it were any other block in your Simulink model.

Thank you for your answer! The problem is that I don't want to put my program into S-function block. My C++ program have to be a stand-alone application which should cooperate with simulink model. Maybe it's possible to build an interface using S-function to exchange data between this two different environments during simulation time..
