3 Basic Procedures
3-32
7 Do one of the following:
- Click
Apply to apply the changes to your model and leave the dialog box
open.
- Click
OK to apply the changes to your model and close the Scope
parameters
dialog box.
When you modify anything in the
Scope parameters dialog box, you must
click the
Apply or OK button for the changes to take effect, and you must
rebuild your real-time application before connecting and starting it. If you
do not rebuild, an error dialog box will open. If you do not click
Apply, your
executable will run, but it will use the old settings.
The reason why you need to rebuild is because the model checksum includes
settings from the Scope block used for signal logging. If the model checksum
does not match the checksum in the generated code, the real-time
application cannot run. Always rebuild your real-time application after
changing Scope parameters.
Entering Signal and Triggering Properties
Data is saved to the MATLAB workspace through a Simulink Scope block.
Signal and triggering properties need to be set only when you are running a
real-time application. If you are running a simulation, you can skip this
procedure.
