OPC UA Configuration Example

The information in this page is updated in accordance with 00.07.03.3 firmware version. .

Introduction

OPC UA (OPC Unified Architecture) is an industrial communication protocol for secure and reliable transfer of real-time data and events between devices and applications in industrial automation and the Internet of Things (IoT).

This article will contain an example on how you can configure a Teltonika-Networks device as an OPC UA Client, that will gather and forward data from an UPC UA Server.

Note: OPC UA is additional software that can be installed from the Services → Package Manager page.

Configuration overview and prerequisites

For this example we will need:

• RUT or TRB series device (RUTX11 will be used in this example)
• OPC UA server

Note: If you're having trouble finding any page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Basic" button under "Mode," which is located at the top-right corner of the WebUI.
