Signal logging

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

Category: Data Import/Export

Default: On, logsout

On

Enables logging data for specified signals to the MATLAB^® workspace and the Simulation Data Inspector.

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

Off

Disables logging signal data to the MATLAB workspace and the Simulation Data Inspector.

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.
Data for variable-size signals is saved as a timetable object with a cell array of values for each time step.
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 Using the 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.
For information about logging Simscape™ data, see About Simulation Data Logging (Simscape).

This parameter enables the Configure Signals to Log button.
