简介

本项目旨在简化OPC的使用，提供了一个简单的API，使得用户可以通过简单的代码实现OPC的读写操作。

使用方法

1. 安装依赖

dotnet add package hongmao.HmExtension.Opc

2. 创建OPC客户端

var client = HmOpcClientFactory.CreateOpcDaClient();

3. 获取OPC服务器列表

var servers = client.GetServers(); // 获取本地OPC服务器列表
// var servers = client.GetServers("127.0.0.1")

4. 连接OPC服务器

client.Host = "127.0.0.1";
client.ServerName = "Kepware.KEPServerEX.V6";
client.Connect();

5. 浏览节点数据

var nodes = client.Browses(); // 浏览节点列表
var treeNodes = client.BrowseTrees(); // 浏览节点树
var node = client.GetOpcNode("Channel1.Device1.Tag1"); // 获取节点信息

6. 读取数据

var node = client.GetOpcNode("Channel1.Device1.Tag1"); // 获取节点信息
var value = client.ReadValue(node); // 读取节点数据

7. 写入数据

var node = client.GetOpcNode("Channel1.Device1.Tag1"); // 获取节点信息
client.WriteValue(100); // 写入节点数据

8. 监听数据变化

var node = client.GetOpcNode("Channel1.Device1.Tag1"); // 获取节点信息
client.OnDataChange += (groupName,oldValue,newValue)=>{
	Console.WriteLine($"数据变化：{groupName} {oldValue} -> {newValue}");
}

9. 断开连接

client.Disconnect();
