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 ]

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
