OPCAE.NET Product Description Reference Manual Version Log
OPC HDA (Historian) .NET Client SDK for C# and VB.NET
You can develop OPC Historical Data Access (HDA) clients in C# or VB.NET without having to think about the OPC DCOM interface. The OPCHDA.NET client SDK provides classes and methods for the .NET Framework and .NetCore platform. The development of applications for the OPC HDA Server access is simple and efficient.
- A .NET method is provided for each OPC HDA specified function. The data is converted to/from .NET data types. The .Net wrapper functions are highly optimized and work in 32-bit and 64-bit operation.
- Additional methods are included as an upper layer to make application development easier and quicker.
- A test client and several sample clients are supplied in C# and VB source code.
- OPCHDA.NET can be used for stand-alone OPC HDA clients or combined with OPCDA.NET and/or OPCAE.NET for OPC DA / HDA / AE client applications.
The HDA Test Client application can be used as a diagnostic tool to see what OPC HDA servers are available and if they can be accessed. The test client can also be used as a development helper tool. The server can be browsed to get the items supported by the server and the item names can be copied into the code of a client being developed. All OPC HDA 1.2 functions can be called interactively to check if the values are returned as expected. This may help determine if an unexpected behavior has to searched in the client being developed or somewhere else.
To make the application test environment complete there is a Test Server included in the OPCHDA.NET package. This server is based on the evaluation version of the Advosol HDANS Server Toolkit and is tested for OPC HDA V1.2 compliance. It can be adapted to meet the application needs. There is for each item a text file with the data. These files can easily be modified and files can be added to have additional items available. As a product evaluation this server has a 30 minute run-time restriction. For software tests this is rarely a restriction since test runs are usually shorter.
