QuickOPC-UA (for OPC Unified Architecture)

Are you having difficulties incorporating the OPC Unified Architecture data into your solution? Need to do it quickly and in quality? If so, QuickOPC-UA comes to the rescue.

QuickOPC-UA is a set of components that simplify the task of integrating OPC into applications. Reading a value from OPC Unified Architecture server, or writing a data value can be achieved in just one or two lines of code.

QuickOPC-UA is a radically new approach to access OPC data. Traditionally, OPC programming required complicated code, even with use of OPC Foundation SDKs. OPC server endpoints must be discovered, connections to OPC Servers must be instantiated, OPC Subscriptions must be created and manipulated, and OPC Monitored Items must be added and managed properly. Too many lines of error-prone code must be written to achieve a simple goal – reading or writing a value, or subscribing to value changes.

The components can be used from various languages and environments. The available examples show how the components can be used from C#, Visual Basic.NET, and managed C++. Windows Forms, ASP.NET pages, Windows services, console applications, and WPF applications are all supported. The development tool we have targeted primarily is Visual Studio 2008 and 2010.

Simple QuickOPC Examples in C#

The code below (in C#) reads and displays a monitored item value, using QuickOPC-UA:

// Obtain value of a node and display it in a message box 
MessageBox.Show(EasyUAClient.DefaultInstance.ReadValue(
    "http://localhost:51211/UA/SampleServer",
    "nsu=http://test.org/UA/Data/;i=10853").ToString());

The code below subscribes to changes of a monitored item value, and displays the value with each change:

// The callback is a lambda expression that displays the value EasyUAClient.DefaultInstance.SubscribeMonitoredItem( "http://localhost:51211/UA/SampleServer", "nsu=http://test.org/UA/Data/;i=10853"), 1000, (_, args) => Console.WriteLine(args.AttributeData.Value));

No other product can do this in such a clear and concise code, in a single statement!

Simple QuickOPC Examples in Visual Basic (VB.NET)

The code below (in Visual Basic) reads and displays a monitored item value, using QuickOPC-UA:


' Obtain value of a node and display it in a message box


            MessageBox.Show(EasyUAClient.DefaultInstance.ReadValue(
    "http://localhost:51211/UA/SampleServer", "nsu=http://test.org/UA/Data/;i=10853"))

The code below subscribes to changes of a monitored item value, and displays the value with each change:

' The callback is a lambda expression that displays the value EasyUAClient.DefaultInstance.SubscribeMonitoredItem( "http://localhost:51211/UA/SampleServer", "nsu=http://test.org/UA/Data/;i=10853", 1000, Sub(sender, args) Console.WriteLine(args.AttributeData.Value))

No other product can do this in such a clear and concise code, in a single statement!
