Signal Logging Basics

Signal logging acquires signal data during a real-time run and stores it on the target computer. After you stop the real-time application, you transfer the data from the target computer to the development computer for analysis. You can plot and analyze the data, and later save it to a disk on the development computer.

Simulink® Real-Time™ signal logging samples at the base sample time.

  • Simulink Real-Time Explorer works with multidimensional signals in column-major format.

  • Some signals are not observable.

You can log signals by:

  • Mark signals for immediate logging to the Simulation Data Inspector.

  • Connect signals to File Log blocks for buffered logging to the Simulation Data Inspector.
