Question

在我的程序中，我需要读取xml文件并将该xml文件中的特定节点发送到PLC。但是在将节点数据写入PLC的过程中，其中一些数据仍然丢失。

我尝试了很多事情，最初使用OPC更改为OPC UA。然后改变了编码方式。但是这些都不起作用，数据只会丢失。下面是我读取xml文件，收集节点（二进制代码）并写入PLC的代码

private void readFromXml()
    {
        Task.Run(() =>
        {
            try
            {
                string inputPath = string.Empty;
                string backupPath = string.Empty;
                string pathConfig = iOPC.ReadTag<string>(UTAC_Tags.Path_Config);
                bool lotRetest = iOPC.ReadTag<bool>(UTAC_Tags.Lot_Retest);
                switch (pathConfig)
                {
                    case "Server":
                        inputPath = lotRetest == false ? SettingFileModel.ServerFolderPath_Input : SettingFileModel.ServerFolderPath_Output;
                        backupPath = lotRetest == false ? SettingFileModel.ServerFolderPath_Backup : FolderPath.RetestXml;
                        break;
                    case "Local":
                        inputPath = lotRetest == false ? SettingFileModel.LocalFolderPath_Input : SettingFileModel.LocalFolderPath_Output;
                        backupPath = lotRetest == false ? SettingFileModel.LocalFolderPath_Backup : FolderPath.RetestXml;

这是错误日志的结果之一。我感谢任何帮助。我已经在这个问题上停留了很长时间了。

服务器告诉您您要写入的NodeId不存在或未知。

您确定构造正确吗？
