To create a user interface to a real-time application, use the C API by using a development environment that can link in a DLL.
To control the real-time application, tune parameters, and acquire signal data, use the user interface application. A user interface application runs on the development computer and communicates with the real-time application on the target computer by using TCP/IP communication. A user interface application can be a console or Windows® application using ActiveX® components.
Support for the Custom UI with Simulink® Real-Time™ C API will be removed in a future release.
