Signal Logging

Visualize signal logging in the Simulation Data Inspector from runs of the real-time application

To log signal values and times, mark signals for logging with the Simulation Data Inspector or add a File Log to your model. See Signal Logging and Streaming Basics.

A File Log block collects signal data on the target computer that is sent to the development computer after each simulation run. Or, if the target computer is not connected to the development computer, you can upload the data to the development computer when you connect to the target computer.
