To log signal values and times, add a real-time file Scope block or an Outport block to your model. At run time, add a real-time file scope with Simulink® Real-Time™ Explorer. See Signal Logging Basics and File Scope Usage.
A file scope creates a file on the target computer that you can download to the development computer for offline analysis. See File System Basics.
An Outport block produces a vector of signal states and times in RAM on the target computer. To download it onto the development computer and store the vector in a file for analysis, use MATLAB®.
