# CANopen Start

## Overview

![The CANopen Start Node.](/files/9rhWDSxTDnWUXlJ88ti8)

THe **CANopen Start Node** starts communication with a **CANopen** connection that has already been set up in [**Project Settings**](/incari-studio/2024.1/modules/project-settings/canopen.md).

It is important to note that while the **CANopen Start Node** starts a **CANopen** connection, it may not completely finish establishing said connection when the **Node** is executed. This could lead to the **Logic** attached to its **Output Pulse** to not work even though there is technically nothing wrong. In order to avoid this, it is highly suggested to use the [**On CANopen Start Node**](/incari-studio/2024.1/toolbox/communication/canopen/events/oncanopenstart.md) instead. This way, the **Logic** will only execute once the **CANopen** connection has definitely been established.

Again, the user must first use the **CANopen Start Node** to open the connection. Separately, the **On CANopen Start Node** can be used to execute the desired **Communication Logic**.
