OPC Classic for .NET

Advosol offers OPC .NET components for the DCOM based classic OPC DA, OPC HDA and OPC AE specifications. Our high performance .NET wrappers work in 32-bit and 64 bit mode.
The Client Development components and Server Toolkits support all .NET versions and can be used with all Visual Studio .NET versions.



OPC .NET (Xi) bridges the gap between Classic OPC and .NET
with a smooth migration from DCOM to WCF communication.
Advosol offers a comprehensive set of Xi products.
Converter servers, Toolkits for Xi servers,
Xi Client SDKs for .NET3, .NET4, .NetCF and Silverlight



To protect your OPC investments, Advosol offers an OPC UA Server Toolkit that uses the same customization plug-in as the Advosol OPC DA, XML DA and Xi server toolkits. Multiple OPC specifications can be supported without additional development effort.
With the OPCDA.NET-UA client component applications can access OPC DA and OPC UA servers through the same API.

OPC Client APIs

OPC client applications are usually implemented based on a commercial component that handles the OPC communication. The interface the client application developer uses is specific to the used component. The Classic OPC specifications define a C++ DCOM interface but no .NET interface. The web services based OPC specifications define the communication records, not the API.
Choose a component with a convenient API that preferably supports multiple OPC specifications for the flexibility increasingly needed.

Free Tools

Advosol offers many free tools. Test clients and simulation servers for OPC DA, HDA, AE and XML DA help in the testing and trouble shooting of OPC client and server applications.
The OpcSecurityAnalyzer shows and explains local and remote DCOM settings and helps resolve access issues.
The AdvosolProductVersions utility offers a quick and easy way to check the current product versions and the recent modifications.
