Set up the OPC UA connector for Easy Integration - TeamViewer Support
<main> <article class="userContent"> <p><br></p><p>📌<strong>Note: </strong>This article applies to all TeamViewer IoT users and requires <strong>TeamViewer IoT Agent 2.11</strong> or higher.</p><p><br></p><h3></h3><h2 data-id="overview">Overview</h2><p>OPC Technology stands for “Open Platform Communications” and is an approved communication standard for the process industry. The OPC Unified Architecture (UA) is an interoperability standard and provides a secure and reliable data exchange mechanism. OPC UA is a platform-independent system and ensures information flow between devices from multiple vendors. For real-time data access, the OPC Data Access specification is being used.</p><p><br></p><h3 data-id="-1"></h3><h2 data-id="architecture">Architecture</h2><p>TeamViewer IoT provides an OPC UA Connector that connects to the OPC UA Server and collects values from OPC UA Variables. The connector communicates with TeamViewer IoT Cloud with the help of the <a href="https://community.teamviewer.com/English/kb/articles/109800-iot-agent-on-linux" rel="nofollow noreferrer ugc">IoT Agent</a>.</p><p>The setup contains three basic steps.
