本文详细介绍了使用C#通过OPCUA协议监控设备的步骤，包括创建应用配置、证书处理，以及如何浏览、读取节点数据。同时，提到了订阅数据并处理变化的数据以实现显示。此外，推荐了OPC Watch作为OPCUA客户端工具，以及KepServerEx用于获取设备信息的OPCUA服务器。

步骤1：创建OPCUA应用配置（包含证书）

 var config = new Opc.Ua.ApplicationConfiguration()
            {
   
   
                ApplicationName = "MyHomework",
                ApplicationUri = Utils.Format(@"urn:{0}:MyHomework", System.Net.Dns.GetHostName()),
                ApplicationType = ApplicationType.Client,
                SecurityConfiguration = new SecurityConfiguration
                {
   
   
                    ApplicationCertificate = new CertificateIdentifier {
   
    StoreType = @"Directory", StorePath = @"%CommonApplicationData%\OPC Foundation\CertificateStores\MachineDefault", SubjectName = Utils.Format(@"CN={0}, DC={1}", "MyHomework", System.Net.Dns.GetHostName()) },
                    TrustedIssuerCertificates = new CertificateTrustList {
   
    StoreType = @"Directory", StorePath = @"%CommonApplicationData%\OPC Foundation\CertificateStores\UA Certificate Authorities" },
                    TrustedPeerCertificates = new CertificateTrustList {
   
    StoreType = @"Directory", StorePath = @"%CommonApplicationData%\OPC Foundation\CertificateStores\UA Applications" },
                    RejectedCertificateStore = new CertificateTrustList {
   
    StoreType = @"Directory", StorePath = @"%CommonApplicationData%\OPC Foundation\CertificateStores\RejectedCertificates" },
                    AutoAcceptUntrustedCertificates = true,
                    AddAppCertToTrustedStore = true
                }
