PLC衔接新方式UcAsp.Opc
作者:互联网
UcAsp.Opc
opc for da and ua
注 意:
[OPC.DA 环境下先安装lib文件夹下的:Core Components Redistributable (x64).msi ]
Nuget 安装
Install-Package UcAsp.Opc -Version 1.0.0.5
OPC.DA 读取变量
OpcClient client = new OpcClient(new Uri("opcda://127.0.0.1/Matrikon.OPC.Simulation.1")); string r = client.Read<string>("Random.String");
OPC.UA 读取变量
OpcClient client = new OpcClient(new Uri("opc.tcp://127.0.0.1:26543/Workstation.RobotServer")); float r = client.Read<float>("Robot1.Axis1"); var list = client.Read(new string[] { "Robot1.Axis1", "Robot1.Axis2" });
读取和写入
OpcClient client = new OpcClient(new Uri("opc.tcp://127.0.0.1:26543/Workstation.RobotServer")); client.Write<float>("Robot1.Axis1", 2.0090f); float r = client.Read<float>("Robot1.Axis1"); var result = client.Write(new string[] { "Robot1.Axis1", "Robot1.Axis2" }, new object[] { 2.0090f, 2.0090f });
分组监听数据变化
public void UAGroup() { OpcClient client = new OpcClient(new Uri("opc.tcp://127.0.0.1:26543/Workstation.RobotServer")); OpcGroup group = client.AddGroup("Test"); client.AddItems("Test", new string[] { "Robot1.Axis1", "Robot1.Axis2" }); group.DataChange += Group_DataChange; } private void Group_DataChange(object sender, System.Collections.Generic.List<OpcItemValue> e) { foreach (OpcItemValue o in e) { Console.WriteLine(o.Value); } }
获取节点信息
OpcClient client = new OpcClient(new Uri("opc.tcp://127.0.0.1:26543/Workstation.RobotServer")); INode root = client.RootNode; IEnumerable<INode> list = client.ExploreFolder(root.Tag); IEnumerable<INode> server = client.ExploreFolder(list.ToList()[0].Tag); IEnumerable<INode> s = client.ExploreFolder(server.ToList()[0].Tag);
