OPC接口技术 谈英姿tanyz 东南大学自控系工业自动化教研室 内容提要 概述OPC基本原理OPCDA接口标准OPCAE接口标准OPCHDA接口标准OPCXML接口标准 OPC基本原理 通用OPC结构及组成对象及接口概述必需的接口定义可选的接口定义服务器地址空间及配置时间同步与顺序发送机制EnumOPC对象属性条目 通用OPC结构及组成 OPC数据访问规范OPC报警和事件规范OPC数据交换规范OPC历史数据访问规范OPC批处理规范OPC安全性规范OPCXML规范 对象及接口概述 OPC对象OPC对象有三个 服务器 OPCServer 组 OPCGroup 和项 OPCItem OPC接口 服务器 OPCServer即OPC启动服务器 通过它获得其他对象和服务的起始类 并用于返回OPCGroup类对象 OPCServer级别有多种属性 其中包含一个OPC服务器对象的状态和版本等信息 这种级别中的对象由客户应用创建 IOPCServer接口包含管理OPCGroup级别中的对象的方法 如将组加入服务器或从服务器中删除组的方法 AddGroup RemoveGroup IOPCBrowseServerAddressSpace接口包含查找服务器地址空间的方法 IOPCCommon接口方法用于通知服务器语言的设置和客户机的名称 标准OPC服务器对象 必需的接口定义 OPC服务器必需的接口有IunknownIOPCServerIOPCCommerIConnectionPointContainer 组 OPCGroup OPCGroup存储由若干OPCItem组成的Group信息 并用于返回OPCItem类对象 OPCGroup级别管理被称为OPCItem的各个过程变量 IOPCItemMgt接口提供将项加入组或从组中删除项的方法 AddItem RemoveItem IOPCGroupStateMgt接口的方法用于处理组专用的参数或复制组 标准OPC组对象 项 OPCItem OPCItem存储具体Item的定义 数据值 状态值等信息 OPCItem级别的一个对象代表与一个过程变量的连接 该对象的唯一接口是OPCItemDisp 关于OPCItem的信息可以在属性表中找到 例如数值 Value 属性或存取路径 AccessPath 属性 OPC项对象 OPC的过程数据构造 OPC项代表了与服务器中的数据的连接 客户程序对OPC项的操作都是通过包容此项的OPC组来进行的 而不是直接把OPC项作为一个对象来操作 每个OPC项都有值 Value 品质 Quality 和时间戳 TimeStamp 三个属性 EnumOPC对象属性条目 OPC客户与OPC服务器 自定义接口与自动化接口 OPCAutomationwrapper Automation client VisualBasic Excel custominterface server Custom client C custominterface server 自定义接口与自动化接口 自定义接口效率高 通过该接口 客户能够发挥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 采用VB等语言的客户一般采用自动化接口 OPCDA接口标准 数据访问方式DA功能实现过程DA的对象与接口 数据访问方式 DA的同步读取DA的异步读取DA的数据更新DA的数据订阅DA的同步写入DA的异步写入 DA的同步读取 DA的异步读取 DA的数据订阅
