# Start Interval

## Overview

![The Start Interval Node.](/files/M9k51mDeLVwuv7ueP10H)

The **Start Interval Node** sets an **Interval**, which occurs every *X* `Seconds` (or `Timeout (sec)`). When the **Start Interval Node** fires, the **Logic** connected to the **Output Pulse Socket** will be repeated every *X* seconds. At the same time, **OnStart** is triggered immediately. An **Instance ID** will be created, thus serving as an input for the **Reset Interval Node**. If **Reset Interval** -- connected by the **Instance ID** -- is triggered, **OnReset** fires.

Important to note is that an **Interval** will continue firing until a **Reset Interval Node** is triggered. Without resetting it, it will run forever.

[**Scope**](/incari-studio/toolbox/overview.md#scopes): **Project**, **Scene**, **Function**.

## Attributes

| Attribute       | Type      | Description                                                         |
| --------------- | --------- | ------------------------------------------------------------------- |
| `Timeout (sec)` | **Float** | The time it takes to reach the next occurrence of the **Interval**. |

## Inputs

| Input             | Type      | Description                                                           |
| ----------------- | --------- | --------------------------------------------------------------------- |
| *Pulse Input* (►) | **Pulse** | A standard **Input Pulse**, to trigger the execution of the **Node**. |
| `Seconds`         | **Float** | The time it takes to reach the next occurrence of the **Interval**.   |

## Outputs

| Output             | Type           | Description                                                                                                                            |
| ------------------ | -------------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| *Pulse Output* (►) | **Pulse**      | A standard **Output Pulse**, to move onto the next **Node** along the **Logic Branch**, once this **Node** has finished its execution. |
| `Instance ID`      | **InstanceID** | The assigned **Instance** of the **Interval**.                                                                                         |
| `OnStart` (►)      | **Pulse**      | Flows to additional actions following **Start Interval** when it starts.                                                               |
| `OnReset` (►)      | **Pulse**      | Flows to additional actions following **Reset Interval** when it is reset.                                                             |
