Simulink Real-Time Explorer

Interact with target computer and real-time application running on target computer

Description

Simulink^® Real-Time™ Explorer provides a single point of contact for viewing connection status and interacting with a real-time application. You can monitor and trace signals, tune parameters, and stream data to the Simulation Data Inspector.

Note

Do not use Simulink external mode while Simulink Real-Time Target Explorer is running. Use only one interface or the other.

Use Simulink Real-Time Explorer for these tasks:

• Connect the development computer and target computer.

• Load, start, and stop a real-time application on target computer.

• View real-time application parameters and signal hierarchy.

• Select real-time application signals for streaming to the Simulation Data Inspector.

• Set real-time application stop time.

• View task execution time (TET).

For examples, click the links in the More Information column.

slrtExplorer

Examples

Configure Target, Update, and Reboot

This example shows how to change the IP address of the target computer, update the target computer software, and reboot the target computer.

Open the Simulink Real-Time Explorer.

Select the target computer in the Targets Tree panel.

To change the IP address of the target computer, click the Change IP Address button.

To update the target computer software, click the Update Software button.

To reboot the target computer, click the Reboot button.

Connect, Load Application, and Start

This example shows how to connect to the target computer, load the real-time application, set the stop time, and start the real-time application.

Open the Simulink Real-Time Explorer.

Select the target computer in the Targets Tree panel.

To connect to the target computer if not already connected, click Disconnected toggling it to Connected.

To select and load a real-time application, click Load Application and select the MLDATX file.

1. To select and load a real-time application by using the context menu, right-click on the application and select Load.

   

To select the application stop time, type a value (in seconds) in the Stop time field.

To start the application, click the Start button.

In Explorer, clicking the Start button is equivalent to executing this command for target object tg:

start(tg, 'ReloadOnStop', true)

1. To change the ReloadOnStop and AutoImportFileLog operation of the Start button, select Start > ReloadOnStopor Start > AutoImportFileLog.

To stop the real-time application, click the Stop button.

Select Signals and Stream Data to Simulation Data Inspector

This example shows how to connect to the target computer, load the real-time application, select signals for a signal list, start the real-time application, and view the streaming data in the Simulation Data Inspector.

Open the Simulink Real-Time Explorer.

To connect to the target computer if not already connected, click Disconnected toggling it to Connected.

To select and load a real-time application, click Load Application and select the MLDATX file.

To select signals for streaming, click the application name, select signals from the Signals tab, and click the Add selected signals button.

To run the application and generate data for streaming, click the Run button.

To stream the signal data, select the signals in the Group signals to stream for SDI list and click the Stream Signal Group to SDI button.

To view the streaming signals, click the Open in SDI button.

After viewing the data, to stop the real-time application, click the Stop button.

Programmatic Use

slrtExplorer

slrtExplorer opens the Simulink Real-Time Explorer. Operations in the Simulink Real-Time Explorer UI correspond to Simulink Real-Time commands. For example, the explorer Start button corresponds to the start function.
