<h1>OPC-UA Example</h1>


<p><a target="_blank" href="https://realtimelogic.com/products/opc-ua/">OPC Unified Architecture (OPC-UA)</a> 
is a machine to machine communication protocol for industrial automation.

<p>The OPC-UA examples bundled in the '<samp>opcua-client.zip</samp>' file (<a target="_blank" href="https://github.com/RealTimeLogic/OPC-UA-Browser">
also available from our GitHub repository</a>)  include both a browser-based user interface and a server-side OPC-UA client. 
The user interface is implemented as an HTML and JavaScript-powered Single Page Application (SPA) that runs 
in the browser and communicates with the server-side client using WebSockets. 
The examples also include an OPC-UA server with the endpoint URL '<samp>opc.tcp://<?lsp=demo.ipaddr?>:4841</samp>'. 
These examples can help you get started with OPC-UA and see how it can be used to build robust and efficient applications.</p>

<p>The client's default OPC-UA endpoint address is to the local OPC-UA server. You can use any OPC-UA server address, 
such as the following public OPC-UA server: <samp>opc.tcp://opcuaserver.com:48010</samp>. You can also connect other (external) 
OPC-UA clients to the server example.</p>
