OPCData.NET is a 100% managed .NET tool for developing OPC DA and A&E clients,  with native support for both 32 and 64 bit operating systems, for  developing any type of application in Visual Studio .NET. More information on the most common uses of the product can be found below.

Thick-Client .NET applications The most typical use of OPC Data.NET involves a thick-client user application written in one of the Microsoft .NET languages. This application uses the types from OPC Data.NET object model, and accesses data within OPC servers that are located on remote computers on the same LAN (Local Area Network). The communication with the target OPC server is performed by Microsoft COM/DCOM technology.

Web applications (server side)

The other typical use of OPC Data.NET is to place it on the Web server inside a Web application. The Web application provides HTML pages to the client’s browser, runs in a Web server, such as Microsoft IIS (Internet Information Server), and is written using tools and languages such as

• ASP/VBScript, PHP, Python and others – any language that supports COM automation, or
• ASP.NET, C#, Visual Basic.NET, or any other .NET language.

The Web application uses the types from OPC Data.NET object model, and accesses data within OPC servers that are located on remote computers on the same LAN (Local Area Network). The communication with the target OPC server is performed by Microsoft COM/DCOM technology. No OPC-related (or indeed, COM or Microsoft-related) software needs be installed on the client machine; a plain Web browser such as Internet Explorer (IE) or FireFox is sufficient.
