File not found or could not be opened for reading

hanpeiwen

I follow the given sample code.When I am trying to load one module to the real controller , it returns the error : RobotStudio .NET exception:  File not found or could not be opened for reading. However , the  module does exist . Here is  my code , any idea? I am a green hand ,thanks a lot !

private static void button_ExecuteCommandSecond(object sender, ExecuteCommandEventArgs e)

        {

            // Step 1: Connect to the controller

            #region LMStep1

            Guid systemId = new Guid("7fa807ce-c383-42b6-8a32-549fcb4cb50d");

            Controller controller = new Controller(systemId);

            controller.Logon(UserInfo.DefaultUser);

            #endregion

            // Clears the eventlogs in the controller

            controller.EventLog.ClearAll();

            // Gets the task with the specified name.

            ABB.Robotics.Controllers.RapidDomain.Task tRob1 = controller.Rapid.GetTask("T_ROB1");

            // Step 2: Select module from PC

            #region LMStep2

            if (System.IO.File.Exists(@D:\Temp\MyModule.mod))

            {

                    string ModulefilePath = @D:\Temp\MyModule.mod;

                    bool bLoadModuleSuccess = false;

                    // Step 3: Load Module 

                    #region LMStep3

                    using (Mastership.Request(controller.Rapid))

                    {

                        // Loads a RAPID module to the task in the robot controller.

                        Logger.AddMessage("The mastership has been gotten.");

                        bLoadModuleSuccess = tRob1.LoadModuleFromFile(ModulefilePath, RapidLoadMode.Replace);      // According to the report ,here happens the error.

                    }

                    #endregion

            }
            #endregion

        }

Hey hanpeiwen,
I know it's been a while, but did you ever solve your question above?
I'm sitting here with what I believe is that same problem. My code closely resembles ABB example for uploading a mod fiel to a controller and it even works on a virtual one.
But as soon as I try it on a physical controller I'm getting the error file not found.
Was hoping you or someone else might have some suggestions to what I'm doing wrong.

Hello,

I think you have to copy your file to the controller before you can load it from there.

As I know it is not possible to load a file directly from the PC into the real controller.

You can use the following method to copy your file:

aController.FileSystem.PutFile(localFilePath, remoteFilePath);

Hello,

Physical controller use Unix folder separator '/'.

Filename could be like this: "HOME:/myfilename.txt".

Look at Open instruction in RAPID manual.

You can use RobOS() to know if you're running in virtual or real robot.
