Export and Import Signals in Instrument by Using Simulink Real-Time Explorer
When testing a complex model with many signals, you frequently must select signals for tracing or monitoring from multiple parts and levels of the model hierarchy.
Save Signals to Disk
You can make this task easier by using Simulink® Real-Time™ Explorer to select the signals in instrument and save the list of signals to disk.
Open model slrt_ex_osc
.
Connect to the target computer. On the Simulink Editor Real-Time tab, toggle the Disconnected indicator to Connected.
Build and download the real-time application to the target computer. Click Run on Target.
Open Simulink Real-Time Explorer. Click Prepare > SLRT Explorer.
To add signals to the signals in instrument, export the list of signals, and import the list of signals.
In Simulink
Real-Time Explorer, click Load Application. Select the
slrt_ex_osc
application from the Applications on
target computer list and click Load.
Click the Signals tab.
Select the signals to monitor from the list and then click Add to
signals in instrument .
To export the list, click Export instrument to file . Name the files and click
Save.
To remove signals from the signals in the instrument, select the signals in the
list, and then click Remove signals from instrument .
To import the list, click Import instrument from file . Select the file and click
Open.
Get MATLAB Code for Signals
When developing an App Designer application or an m-script that connects to a real-time application, it is helpful to have MATLAB code for the signals in the instrument. This code provides access to signals in an Instrument object (or instrumented signals), which are signals that are configured for streaming signal data from a real-time application. To generate this code from the Signals in Instrument:
In Simulink
Real-Time Explorer, click Load Application. Select the
slrt_ex_osc
application from the Applications on
target computer list and click Load.
Click the Signals tab.
Select the signals to monitor from the list, and then click Add to
signals in instrument .
To create MATLAB code for the signals in the instrument, click
Generate MATLAB code to create Instrument programmatically . An editor window opens in MATLAB and displays
the code for the signals in the Instrument.
