Simulink Real-Time Explorer

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

Since R2020b

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).

When the ECU page and XCP page selections do not match, the mismatch disables the explorer Parameter table. You can enable parameter table operation by coordinating ECU page and XCP page selection in the real-time application. Use the explorer Enable Parameter Table button. This button is context sensitive and appears when explorer detects a page selection mismatch.	copyPage getECUPage getNumPages getXCPPage setECUAndXCPPage setECUPage setXCPPage
Refresh cached parameter table values by clicking the Refresh Values button.	Use the Refresh Values button for instances in which the parameter table data becomes disabled (for example when page switching occurs),
Use the Hold Updates button and Update All Parameters button to change multiple parameter values simultaneously. These buttons in Explorer operate in the same way as these buttons on the Real-Time tab in the Simulink Editor.	Tune Parameters by Using Hold Updates and Update All Parameters
Use the Save Param Set or Load Param Set buttons on the Parameters tab to save or load a parameter set file for the current real-time application. You can save or load the parameter set file from the development computer or target computer. See the figure.	Save and Reload Parameters by Using Simulink Real-Time Explorer

Open the Simulink Real-Time Explorer

From the Simulink Editor, in the Real-Time tab, select Prepare > SLRT Explorer. Or, from the MATLAB^® Command Window, type:

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.

1. Open the Simulink Real-Time Explorer.

2. Select the target computer in the Targets Tree panel.

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

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

5. 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.

1. Open the Simulink Real-Time Explorer.

2. Select the target computer in the Targets Tree panel.

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

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

   Note

   You can select and load a real-time application by using the context menu. Right-click on the application and select Load.

   

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

6. 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, 'AutoImportFileLog', true)

   Note

   To change the ReloadOnStop and AutoImportFileLog operation of the Start button, you can:

   • Select Start > ReloadOnStop

   • Select Start > AutoImportFileLog.

   Note

   To change the AutoImportFileLog operation of the Stop button, you can:

   • Select Stop > AutoImportFileLog.

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

Select Signals and Stream Data to the 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.

1. Open the Simulink Real-Time Explorer.

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

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

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

Version History

Introduced in R2020b

R2023a: Parameter Set Support

The Simulink Real-Time Explorer supports save or load of a parameter set to or from the development computer or target computer. This support is similar to the operation of the loadParamSet and saveParamSet functions.

R2023a: UI enhancements for file log import options

In Simulink Real-Time Explorer, you can enable the AutoImportFileLog check box from the Run button or Stop button. This check box corresponds to the AutoImportFileLog option of the start function and stop function.

R2022b: Added Recording Buttons and Import File Log Button

Added Start Recording button and Stop Recording button to the Real-Time tab in the Simulink Editor and in the Simulink Real-Time Explorer. The Start Recording button and Stop Recording button have the same functionality as the startRecording function and stopRecording function.

R2022a: Parameter Table Caching and Parameter Tuning

The Parameters tab supports caching parameter table data. By caching the data, updates to parameter data in the table is improved. This improvement is noticeable for real-time applications that have a substantial number of parameters.

The Parameters tab supports a Hold Updates button and Update All Parameters button to change multiple parameter values simultaneously.

R2021b: Disk Usage Display

The target computer disk usage appears on the Target Configuration tab and appears on the target computer status monitor.

R2021a: Added Right-Click Menu for Application Options and Add Options to Start Button

The Explorer provides access to real-time application actions and properties through an application context menu and access to real-time application start options through the Start button. When you right-click an application name in the Targets Tree, the Explorer displays a menu of actions for the application. The application Start button provides ReloadOnStop and AutoImportFileLog options.
