# CODESYS V3 TCP
The Neuron CODESYS V3 TCP plugin enables access to PLCs and motion control systems based on the CODESYS V3 platform through the TCP protocol.
## Device Settings
| Field    | Description                                     |
| -------- | ----------------------------------------------- |
| host     | Device IP address                               |
| port     | Device port, default is 11740                   |
| timeout  | Request send/receive timeout, default is 3000ms |
| username | Device username                                 |
| password | Device password                                 |

If the device logs in anonymously, fill in "Anonymous" as the username and leave the password blank.
