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 target computer to 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. If you have a model with multiple sample rates, add Simulink Real-Time scopes to the model to sample signals at the required sample rates.

  • The Simulink Real-Time software does not support logging data with decimation.

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

  • Some signals are not observable.

You can log signals using the following methods:

  • Outports in the model

  • File scope blocks in the model

  • File scopes created using Simulink Real-Time Explorer

  • File scopes created using MATLAB® language
