Troubleshoot Parameters Not Accessible by Name

I cannot observe or tune some parameters in the real-time application.

What This Issue Means

Reasons that you cannot observe or tune some parameters in the real-time application are:

  • Simulink® Real-Time™ does not support parameters of multiword data types.

  • During execution, you cannot tune parameters that change the model structure, for example by adding a port. To change these parameters, you must stop execution, change the parameter, and rebuild the real-time application.
