Run Real-Time Application

Interactive execution with development and target computers

When you run the real-time application, you can start and stop execution; observe signals and log signal data; and tune real-time application parameters.

You can use the following interfaces to run the application:

Simulink^® Real-Time™ Explorer and Simulink external mode. See Create and Run Real-Time Application from Simulink Model.
MATLAB^® language. See Control and Instrumentation with MATLAB.
Simulink Real-Time RTOS commands from the target computer command line. See Control Real-Time Application at Target Computer Command Line.
