Reset Function

Executes contents on a model reset event

• Library:

• Simulink / User-Defined Functions

Description

The Reset Function block is a pre-configured subsystem block that executes on a model reset event. By default, the Reset Function block includes an Event Listener block with Event set to Reset, a Constant block with Constant value set to 0, and a State Writer block.

Replace the Constant block with source blocks that generate the state value for the State Writer block.

Conditionally executed subsystem blocks with output ports are fully supported within Reset Function blocks.

For a list of unsupported blocks and features, see Initialize, 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, Reset Function, or Terminate Function block or a corresponding state owner block to highlight blocks related to it.

Model Examples

Working with the Initialize Function, Reset Function, and Terminate Function Blocks

Use the Initialize Function, Reset Function, and Terminate Function blocks to read and write states in a Simulink model.
