本讲介绍OPC软件PC Access SMART的使用方法,以及S7-200 SMART通过OPC与组态软件通信的实现方法~([1])。1OPC软件PC Access SMART的使用方法OPC是嵌入式过程控制标准,是用于服务器(Server)/客户机(Client)链接的、统一的、开放的接口标准和技术规范。使用OPC以后,数据用户不用为不同厂家的数据源开发驱动程序或服务程序,最终用户也不用安装各种设备的驱动程序,系统集成的成本将显著降低。
This talk introduces how to use the OPC software PC Access SMART and how to communicate with the S7-200 SMART via OPC and configuration software ~ ([1]). 1OPC Software How to Use PC Access SMART OPC is an embedded process control standard and is a uniform and open interface standard and specification for server / client links. After using OPC, data users do not need to develop drivers or service programs for data sources from different manufacturers. End users do not need to install drivers for various devices, and the cost of system integration will be significantly reduced.
