支持用C#和VB.NET编程语言开发OPC服务器和OPC客户端程序。
The OPC .NET API is primarily intended to provide interoperability between existing OPC specifications and applications developed in the .NET environment. The API does support COM based and SOAP/XML based servers via the same set of interfaces, however, the API does not introduce new concepts or data models. In other words, the .NET API is intended provide an intermediate step between the existing OPC technologies and the new technologies which are part of the Unified Architecture initiative.
System Requirements
Operating Systems
The OPC .NET API requires that the .NET Framework Redistributable 1.1 or the .NET Framework SDK Version 1.1 is present on the target system. The .NET framework does not support Windows 95.
All source code provided by the OPC Foundation is only supported on Windows 2000 SP3 and Windows XP SP1. That said; the source code has been designed to be portable to other operating systems. For this reason vendors are encouraged to report fixes required to port the samples to other operating systems so they can be incorporated into the baseline and to improve the portability of future sample code.
Source Code
The source code projects require either Visual Studio 6.0 or Visual Studio .NET 2003.
Visual Studio .NET 2003 can be installed along side both Visual Studio .NET 2002 and Visual Studio 6.0. Existing projects for older development environments do not need to be upgraded in order to use sample code distributed by the OPC Foundation.
Installation
SDK
The SDK installs the assemblies and documentation files in the directory:
$(ProgramFiles)\OPC Foundation\NET API 1.30
The SDK also installs the assemblies in the Global Assembly Cache (GAC).
File | Description | OpcNetApi.dll | The base .NET API assembly. | OpcNetApi.xml | The base .NET API assembly VS .NET intellisense documentation file. | OpcNetApi.Com.dll | The .NET API COM Wrapper assembly. | OpcNetApi.Com.xml | The .NET API COM Wrapper assembly VS .NET intellisense documentation file. | OpcNetApi.Xml.dll | The .NET API SOAP/XML Wrapper assembly. | OpcNetApi.Xml.xml | The .NET API SOAP/XML Wrapper assembly VS .NET intellisense documentation file. | OpcRegSvr.exe | A utility used to register .NET assemblies as COM servers. |
Merge Module
The merge module installs the binaries into the Global Assembly Cache (GAC).
Source Code
The source code for the assemblies and the sample client applications are installed by default in the directory:
$(ProgramFiles)\OPC Foundation\NET API 1.30
The source code installation consists of the following key projects in the 'Source' sub directory:
File | Description | NET API | The base .NET API C# project source. | NET API\COM Wrapper | The .NET API COM Wrapper C# project source. | NET API\XML Wrapper | The .NET API SOAP/XML Wrapper C# project source. | NET API\Sample Client\Ae | The .NET API Sample Alarms and Events Client C# project source. | NET API\Sample Client\Da | The .NET API Sample Data Access Client C# project source. | NET API\Sample Client\Dx | The .NET API Sample Data eXchange Client C# project source. | NET API\Sample Client\Hda | The .NET API Sample Historical Data Access Client C# project source. | NET API\Sample Client\ScPL | | NET API\Sample Server\Da | The .NET API Sample Data Access Server C# project source. | NET API\Sample Server\RegSvr | A utility used to register .NET assemblies as COM servers. |
Usage
SDK
You may add the OPC .NET API to your VS .NET projects by opening the 'Add Reference' dialog and navigating to $(CommonProgramFiles). Once this is done the VS .NET intellisense should automatically pick up the documentation files.
The OpcRegSvr utility operates like regsvr32. For example the following command registers the sample COM server:
OpcRegSvr /r .\OpcDaSampleServer.dll
Source Code
The source code builds the assemblies and signs them with a test key-pair. This means that any application that uses the .NET API must be changed so that it references the new assemblies
Problem Reporting
As part of a broader initiative to increase adoption of OPC specifications and to improve service to members, the OPC Foundation intends to maintain binaries and sample code over time following a model similar to Open Source projects. Vendors are encouraged to report problems, bug fixes, enhancements and any other comments about the components supplied by the OPC Foundation. To support this effort, the OPC Foundation has technical staff prepared to review and incorporate feedback into the baseline and release new versions of the components and sample code in a timely manner for the benefit of all members.
Please note that this support is intended for OPC Foundation members who are incorporating OPC support into their products.
