Signal logging

Description

Globally enable or disable signal logging to the workspace for this model.

Category: Data Import/Export

Settings

Default: On, logsout

On

Enables signal logging to the MATLAB® workspace during simulation.

Specify the name of the signal logging object used to record logged signal data in the MATLAB workspace. For more information, see Specify a Name for Signal Logging Data.

Off

Disables signal logging to the MATLAB workspace during simulation.

Tips

  • You must select the Signal logging check box before entering the signal logging variable.

  • Simulink® saves the signal data in a MATLAB workspace variable with the specified name.

  • The saved data is a Simulink.SimulationData.Dataset object.

  • When signal logging is disabled, signals marked for logging still send data to the Simulation Data Inspector.

  • Simulink does not support signal logging for the following types of signals:

    • Output of a Function-Call Generator block

    • Signal connected to the input of a Merge block

    • Outputs of Trigger and Enable blocks

  • If you select Signal logging, you can use the Configure Signals to Log button to open the Signal Logging Selector. You can use the Signal Logging Selector to:

    • Review all signals in a model hierarchy that are configured for logging

    • Override signal logging settings for specific signals

    • Control signal logging throughout a model reference hierarchy in a streamlined way

    You can use the Signal Logging Selector with Simulink and Stateflow® signals.

    For details about the Signal Logging Selector, see View Logging Configuration with Signal Logging Selector and Override Signal Logging Settings.

  • Do not use a variable name that is the same as a Simulink.SimulationOutput object function name or property name.

Dependencies

This parameter enables the Configure Signals to Log button.
