Description: :OPC 规范是由OPC 基金会制定的一个工业标准,它规范了过程控制和生产自动化软件与
用OPC 服务器实现的硬件驱动程序之间的开放接口. OPC 规范得到越来越多的工控领域硬件、
软件制造商的承认和支持,而中国也于2000 年12 月正式加入OPC 基金会,这意味着OPC 也将
成为中国工控界的公认标准. 本文介绍了OPC 的体系结构、数据存取规范的对象和接口、数据存
取规范中的事件驱动,并讨论了OPC 数据访问客户端的开发.-: OPC specification was developed by the OPC Foundation, an industry standard, which standardized the process control and production automation software with the use of OPC server hardware driver interface between the open. OPC specification to be more and more industrial areas of hardware , the software manufacturer Platform: |

Description: 本源码是基于C++开发的OPC客户端程序开发实例。
OPC(OLE for Process Control)是根据Microsoft的OLE(现在Active)、COM(部件对象模型)和DCOM(分布式部件对象模型)技术所要求的功能制定的一个开放和互用式的用户界面标准，它保证了自动化/控制应用程序和区域系统/设备之间的互用。它以OLE/COM机制作为应用程序级的通讯标准，采用CLIENT/SERVER模式。
OPC规范中提供了两套接口方案，即定制接口和自动化接口。定制接口效率高，通过该接口能够发挥OPC服务器的最佳性能，采用C++语言的客户一般采用定制接口方案;自动化接口使解释性语言和宏语言访问OPC服务器成为可能(The source code is based on C++ development OPC client program development examples.
OPC (OLE for Process Control) is based on the Microsoft OLE (now Active), COM (component object model) and DCOM (Distributed Component Object Model) technology requires a functional formulation of an open and interoperable style user interface standard, it guarantees the interoperability of automation / control applications and system / region between devices. It uses the OLE/COM mechanism as the application level communication standard and adopts the CLIENT/SERVER mode.
The OPC specification provides two sets of interface schemes, namely, custom interfaces and automated interfaces. Custom interface and high efficiency, the best performance can play through the interface of the OPC server, using C++ language customers generally use custom interface scheme; automation interface enables explanatory language and macro language possible to access the OPC server) Platform: |

Description: 通过这样的方式便将OPC 规范定义的接口全部引入到现在的工程
中，以后不需要对这些接口和这些接口的方法进行修改。
如第二章所示，完成一个简单的组件并不复杂。然而对于OPC 服务
器的开发，仅仅接口这一块的工作就比较大。(In this way, the interfaces defined by the OPC specification are all introduced into the current project
There is no need to modify these interfaces and methods for these interfaces later.
As you can see in the second chapter, it's not complicated to complete a simple component. However, for OPC services
Device development, only the interface, this piece of work is relatively large.) Platform: |
