OPC HDA .NET Server Toolkit

Version Info

HDANSrv is an OPC Historian server toolkit that allows the HDA server logic to be fully implemented in C# or VB.NET. The code is structured into classes for simple adaptation to the user needs and for high performance access to different kinds of databases. The code is separated in a generic server and a customization plug-in .Net assembly. The generic server implements the local/remote COM server interface and the .NET wrapper that converts all client call arguments to .Net data types. The provided sample servers are tested with the OPC Foundation Compliance Test Tool for full OPC HDA 1.2 compliance. Complete source code is provided and the code is well structured and extensively documented. The custom server development can be as simple as adapting the database access methods. Standard Edition Server Toolkit Features OPC HDA V1.2 compliant Generic server as a local/remote COM server with a high performance .NET wrapper. Works in 32-bit and 64-bit mode with the same customization plug-in assembly. Application specific handling is in a .NET Assembly that can be programmed with VB.Net, C# or any .NET compiler. Full source code provided. The generic server is coded in C++ and the sample server are provided in C# and VB .Net. The documentation is supplied as a Windows help CHM file and as a Help2 component that integrates into the Visual Studio help system and offers context sensitive help. Test client that allows the interactive execution of all OPC HDA defined functions. Simple deployment. The Standard Edition supports of all mandatory HDA features and also the optional asynchronous read functions. The Professional Edition with support of all optional HDA features will be available soon.     Professional Edition Server Toolkit Features Same features as the Standard Edition Additionally supports the optional OPC HDA Update, Playback and Annotations features.

System Requirements
	Windows XP, Windows 2000 or Windows Server 2003 .NET Framework 1.1 or Framework 2.0
	Microsoft Visual Studio .NET 2003 or 2005 Visual Basic or C#

Server Development

The generic server converts all client call parameters to .Net types and calls the appropriate method in the customization plug-in. All application specific server handling can be implemented in C# or VB.Net, using only .Net data types.
The provided sample servers are used as the starting point for custom server development projects. Depending on the application requirements the server development can be as simple as adapting the database read methods.

Visual Studio Integrated Help
The server documentation is provided as a Windows help CHM file and as a Help2 component that plugs into Visual Studio help and supports Context sensitive help that displays the needed information without long searches, just click F1 on the name.

Test Client
All OPC HDA defined functions can be called interactively.
This test client is a .Net application, built with the OPCHDA.NET component, which is available as a separate product.

.NET applications can access OPC AE server through a set of conveniant classes and methods. The EventView control handles a wide range of OPC Alarms&Events viewing requirements. OPC Alarms&Events .NET clients can be created without writing code and without knowledge of the OCP AE specification.
