利用OPC通过工业以太网实现自动计量

Automatic Metering with OPC Protocol by Industrial Ethernet

采用开放式OPC协议实现从工业以太网采集工业PLC数据,目的在于在不需要增加硬件的情况下利用编程,以软件方式直接从以太网上采集数据。通过OPC协议用VC++面向对象的高级语言编程。所编程序在OPC各个方面应用广泛。它能够完成工业网的数据大量采集,程序结构统一,对于不同类型结构的工业数据其接口统一。为工业自动化各二级系统提供稳定和准确的数据。

The purpose of using opened OPC protocol to sample industrial PLC data from industrial Ethernet, is to sample data directly from Ethernet by software mode without needing to add any hardware but programming. By OPC protocol, the program is developed with VC＋＋6.0, which is widely used in different fields of OPC and can finish a great amount of data sampling of industrial Ethemet, and has a uniform structure and uniform interface for different kinds of industrial data, providing the stable and exact data for the second level system.
