QuickOPC for OPC-UA
(OPC Unified Architecture)

Are you having difficulties incorporating the OPC Unified Architecture (also known as OPC-UA, or IEC 62541) data into your solution? Need to create an OPC client supporting OPC-UA quickly and in quality? If so, QuickOPC comes to the rescue.

QuickOPC is a set of components that simplify the task of integrating OPC client functionality 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 is a radically new approach to access OPC-UA 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 OPC UA client development components can be used from various languages and environments. The available examples show how the components can be used from C#, Visual Basic.NET, PowerShell, managed and native C++, VB 6.0, VBA (Excel), VBScript, Delphi (Object Pascal), Python, Perl, PHP and more. 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.
