## Overview

**On TCP Packet Receive** is an **Event Listener Node** that listens to an established **TCP** connection and outputs the `Message` data given, therefore enabling the user to trigger a **Logic Branch** when the `Message` is received.

**TCP Communication** in **Incari** is available as a plugin and is enabled as default. However, in the case that it is disabled in the **Plugins Editor**, it will not appear in the **Project Settings** and **On TCP Packet Receive** will not show up in the [**Toolbox**](https://github.com/cgi-studio-gmbh/incari-doc/blob/2023.1/toolbox/communication/overview.md). Please refer to the [**Plugins Editor**](https://docs.incari.com/incari-studio/2023.1/modules/plugins/communication/tcpconnectionsmanager) to find out more information.

[**Scope**](https://docs.incari.com/incari-studio/2023.1/overview#scopes): **Project**, **Scene**.

| *Pulse Output* (►) | **Pulse**  | A standard **Output Pulse**, to move onto the next **Node** along the **Logic Branch**, once this **Node** has finished its execution. |
| `Message`          | **String** | The returned `Message`.                                                                                                                |
