Signal Logging to a File

Logging signals to a file saves data to a variable in your MATLAB® workspace, and then saves that data to a MAT-file. You can use MATLAB functions for data analysis and MATLAB plotting functions for visualization on the data in the MAT-file.

The steps in this process are:

  1. Set Scope Parameters for Logging to File

  2. Set Run in Kernel Mode Properties for Logging to File

  3. Set Run in Kernel Mode Data Archiving Parameters

  4. Plot Signal Data Logged to File by Simulink Desktop Real-Time

If your model contains Outport blocks, you cannot save signal data in Run in Kernel mode. Simulink® supports signal logging to a file in Connected IO mode or accelerator mode only, when Simulink runs the simulation algorithm.

Tip

In Run in Kernel mode, do not enter or select parameters on the Data I/O tab in the Configuration Parameters dialog box. Instead, add a Scope block to your Simulink model and use it to log signal data for data archiving.
