Multitask data transfer


Select the diagnostic action to take if an invalid rate transition occurred between two blocks operating in multitasking mode.

Category: Diagnostics


Default: error


Simulink® software displays a warning.


Simulink software terminates the simulation and displays an error message.


  • This parameter allows you to adjust error checking for sample rate transitions between blocks that operate at different sample rates.

  • Use this option for models of real-time multitasking systems to ensure detection of illegal rate transitions between tasks that can result in a task's output being unavailable when needed by another task. You can then use Rate Transition blocks to eliminate such illegal rate transitions from the model.
