FTP : Full file management

FTP provides complete file management: upload, download, delete, rename, and directory operations.

using UnderAutomation.Fanuc;

public class FtpFileManagement
{
  static void Main()
  {
    FanucRobot robot = new FanucRobot();
    ConnectionParameters parameters = new ConnectionParameters("192.168.0.1");
    parameters.Ftp.Enable = true;
    parameters.Ftp.FtpUser = "";
    parameters.Ftp.FtpPassword = "";
    robot.Connect(parameters);

    
    // Upload a TP program to the controller
    robot.Ftp.DirectFileHandling.UploadFileToController(@"C:\Programs\MyPrg.tp", "md:/MyPrg.tp");

    // Download a file from the robot
    robot.Ftp.DirectFileHandling.DownloadFileFromController(@"C:\Backup\Backup.va", "md:/Backup.va");

    // Delete a file
    robot.Ftp.DirectFileHandling.DeleteFile("md:/OldProgram.tp");

    // List files in a directory
    var items = robot.Ftp.DirectFileHandling.GetListing("md:/");
    foreach (var item in items)
      Console.WriteLine($"{item.Name} ({item.Type})");

    // Create and delete directories
    robot.Ftp.DirectFileHandling.CreateDirectory("md:/NewFolder");

    // Rename a file
    robot.Ftp.DirectFileHandling.Rename("md:/old.tp", "md:/new.tp");

    // Check file existence
    bool exists = robot.Ftp.DirectFileHandling.FileExists("md:/MyPrg.tp");
    
  }
}

FanucRobot robot = new FanucRobot();
robot.Connect("192.168.0.1");
// Backup: list all files and download
FtpListItem[] files = robot.Ftp.DirectFileHandling.GetListing("md:/");
foreach (var file in files)
{
    robot.Ftp.DirectFileHandling.DownloadFileFromController($"backup/{file.Name}", $"md:/{file.Name}");
}

// Upload a .tp file
robot.Ftp.DirectFileHandling.UploadFileToController("C:/programs/MY_PROGRAM.tp", "md:/MY_PROGRAM.tp");

// Download specific variable files
robot.Ftp.DirectFileHandling.DownloadFileFromController(out byte[] numreg, "md:/numreg.va");
robot.Ftp.DirectFileHandling.DownloadFileFromController(out byte[] posreg, "md:/posreg.va");

// Or use convenience methods
NumregFile regs = robot.Ftp.KnownVariableFiles.GetNumregFile();
}
}

CGTP : File download via HTTP

CGTP provides file listing and download through the robot's web server:

FanucRobot robot = new FanucRobot();
robot.Connect("192.168.0.1");
// List TP programs
CgtpAsciiFileItem[] programs = robot.Cgtp.Http.ListTpPrograms();

// Download a file as string
string content = robot.Cgtp.Http.DownloadAsString("numreg.va");

// Download a file as bytes
byte[] data = robot.Cgtp.Http.DownloadAsBytes("posreg.va");

// List files via CGTP protocol
string[] files = robot.Cgtp.ListFiles("MD:");
}
}
