Multitask data transfer

Diagnostic action to take for unspecified data transfers between tasks

Model Configuration Pane: Diagnostics / Sample Time

Description

The Multitask data transfer parameter specifies the diagnostic action to take if an invalid rate transition occurred between two blocks operating in multitasking mode.

Settings

error (default) | warning
warning

Simulink® software displays a warning.

error

Simulink software terminates the simulation and displays an error message.

Tips

  • 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.
