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. Signal logging is also known as real-time data streaming to the target computer. 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 scopes in the model
Virtual file scopes created using Simulink Real-Time Explorer
Virtual file scopes created using MATLAB® language
