# Select Data

## Overview

![The Select Data Node.](https://3875032344-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FSX7w874Eg6ode1ivk0ZM%2Fuploads%2Fgit-blob-0d4a50af2645ba8b9c9c1766166a079dc83f43ec%2Fnode-select-data.png?alt=media)

Because **Input Data Sockets** in **Incari** can only receive a value from a single connection, this creates a problem when you wish to converge the **Logic** into a single branch. This is why the **Select Data Node** was introduced, which takes two or more pairs of **Pulse** and **Data** inputs and outputs the value corresponding to the input **Pulse** that the **Node** was executed by.

## Attributes

| Attribute   | Type          | Description                                                                   |
| ----------- | ------------- | ----------------------------------------------------------------------------- |
| `Data Type` | **Drop-down** | The type of data that will be plugged into the `Input` **Sockets**.           |
| `Count`     | **Int**       | The number of **Input Pulses** and **Data Values** the **Node** will receive. |

## Inputs

| Input       | Type                                          | Description                                                          |
| ----------- | --------------------------------------------- | -------------------------------------------------------------------- |
| `Pulse [n]` | **Pulse**                                     | The **Pulse** corresponding to the **Data** in the **Socket** below. |
| `Input [n]` | *Defined in the `Data Type`* ***Attribute**.* | The **Data Value** corresponding to the above **Pulse**.             |

## 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. |
| `Output`           | *Defined in the `Data Type`* ***Attribute**.* | The **Data Value** received in the `Input` **Socket** corresponding to whichever `Pulse` triggered the execution of the **Node**.      |

## Example Usage

The **Select Data** **Node** is particularly useful for optimizing our **Logic** workflow in order to avoid repetition of **Nodes**. The following example shows how to use the **Select Data** **Node** to merge two branches of **Logic** into a single one.

The image above shows two branches that have the same effect (modify a **Text** **Object**) and could converge into a single one. For this, the **Select Data** **Node** is introduced:
