Execute subsystem on model reset event

Libraries:
Simulink / User-Defined Functions

Description

The Reset Function block is a preconfigured Subsystem block that executes on a model reset event. By default, theReset Function block includes:

• An Event Listener block with the Event type set to Reset and the Event name set toreset
• A Constant block with the Constant value set to 0
• A State Writer block with noState owner block set

Customize the contents of the Reset Function block by, for example, replacing the Constant block with source blocks that generate the state value for the State Writer block and specifying a State owner block for the State Writer block.

Conditionally executed subsystems with output ports are fully supported withinReset Function blocks.

For a list of unsupported blocks and features, see Initialize, Reinitialize, Reset, and Terminate Function Limitations.

A model can potentially have multiple Reset Function blocks with each block having a different Event name. Each of these reset events appear in the generated code as a different function.

You can select an Initialize Function, Reinitialize Function, Reset Function, or Terminate Function block or a corresponding state owner block to highlight blocks related to it. To show a related block in an open diagram or new tab, pause on the ellipsis that appears after selection. Then, select Related Blocks from the action bar. When multiple blocks correspond to the selected block, a list of related blocks opens. You can filter the list of related blocks by entering a search term in the text box. After you select a related block from the list, window focus goes to the open diagram or new tab that shows the related block.
