OPC客户端源码，读取DCS OPCSERVER实时数据-OPC client source code, read real-time data of DCS OPCSERVER

这是通过C#编程的OPC客户端程序，OPC连接下位机的大部分功能都能实现-this program bases on C# language,this OPC Client can realize the most of function of PLC or DCS system

C#下基于OPC的数据通讯程序，可连接目前绝大多数通讯DCS。-C# under the OPC-based data communication program, can be connected to the vast majority of communications DCS.

OPC是为了连接数据源(OPC服务器)和数据的使用者(OPC应用程序)之间的软件接口标准。数据源可以是PLC，DCS，条形码读取器等控制设备。-OPC is to connect users to data sources (OPC server) and data software interface standard (OPC applications) between. The data source can be PLC, DCS, bar code reader and other c
