Description

Simulink® Real-Time™ Instrument Viewer tool provides a user interface to view and modify instrumented signals from a real-time application that have been added to a Target object. You can view and modify instruments by using Instruments for SDI, Instruments for MATLAB, and Instruments for FileLog selections.

Use the Simulink Real-Time Instrument Viewer for these tasks:

  • Create a new instrument — After naming the instrument, you can select signals to add to the instrument. These signals appear as Signals added by addSignal() in the Instrumented Signals list.

  • Export instrument(s) to file

  • Import instrument from file

  • Disable instrument or enable instrument

  • Edit instrument name

  • Copy instrument

  • Paste instrument

  • Remove instrument

  • Refresh dialog box

Use the Instrument Viewer app to view, create, or remove instruments.

Open the Simulink Real-Time Instrument Viewer App

After connecting to the Target object tg, in the MATLAB® Command Window, type: 

view(tg.Instruments)

Examples

This example shows how to instrument a signal from a real-time application and configure the instrument for file logging on the target computer by using the Simulink Real-Time Instrument Viewer.

Open an example Simulink model, for example, slrt_ex_osc_rt. In the Command Window, type:

openExample('slrt_ex_osc.slx')

Create a target object and connect to the target computer. Open the model and configure the model for the target computer. Build the model. 

tg = slrealtime;
connect(tg);
model = 'slrt_ex_osc';
modelSTF = getSTFName(tg);
set_param(model,"SystemTargetFile",modelSTF);
slbuild(model);
load(tg,model);

At this point, you can define instruments programmatically to add signals to the instruments by using addForFileLog, addForMATLAB, or addForSDI. Instead, the next steps use the Instrument Viewer user interface to add instruments.

Open the Instrument Viewer. In the Command Window, type:

view(tg.Instruments);

In the Instruments Configured For … window, select Instruments for FileLog, then click Create. Name the instrument signal1FileLog. In the Signal Selector dialog box, expand the Named Signals node and select the SigGen signal. Add the signal to the instrument and click OK.

Use the Instrument Viewer app to view, create, or remove instruments.

The Instruments Configured For … window displays the signal that you added to the instrument.

Parameters

No parameters are available for this application.

Programmatic Use

view(tg.Instruments) opens the Simulink Real-Time Instrument Viewer app and displays available instruments in the Target object tg.
