Could you be more specific about what problem you are having?

Tedenljung

The PC project is almost a copy of Read/Write example from the manual. But I have changed it to show the problem in a textbox. I just want to Read/Write to a Num or Array when the program is finished.

The problem is that I fill in Task, Module and valuename and dubbleclick on the robot in found robots. The only answer I get is "invalid client id", whats wrong?

ABB.Robotics.GenericControllerException: Invalid client id.

at Adapters.Data.Get()

at ABB.Robotics.Controllers.RapidDomain.RapidData.get_Value()

at ModifySample.BasicControllerForm.ListView1_DoubleClick(Objec t sender, EventArgs e) in c:Visual Studio 2005ProjectsABBSamplesModifySampleModifySampleBasicCon trollerForm.vb:line 50

 

 

Real IRC5 controller version 5.09.01
RAB version 5.09

I hope this is better info of the problem.

Now I have fixed some other stuff but the main problem is still there!
I Can't get any value from the controller, I have now tested with both Virtual and Real Controller... Same problem, as post above.

Can somebody help?

Hello Daniel,
you need to logon the controller and then request mastership. Example added to your project:

 

Private Sub btGet_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btGet.Click

Dim item As ListViewItem = Me.ListView1.SelectedItems(0)

Dim CtrlInfo As ControllerInfo

Dim myUserInfo As UserInfo = New UserInfo("Default User")

If Not item.Tag Is Nothing Then

CtrlInfo = DirectCast(item.Tag, ControllerInfo)
If Not CtrlInfo.Availability = Availability.Available Then
Return
End If
Me.Ctrl = ControllerFactory.CreateFrom(CtrlInfo)
End If
If Me.Ctrl Is Nothing Then Return
' Codesample
Dim rd As ABB.Robotics.Controllers.RapidDomain.RapidData = Nothing
Ctrl.Logon(myUserInfo.DefaultUser)
Dim master As Mastership = Mastership.Request(Me.Ctrl.Rapid)

Try

rd = Ctrl.Rapid.GetRapidData(tbTask.Text, tbModule.Text, tbValue.Text)
If rd = Nothing Then
Return
End If
RichTextBox1.Clear()
RichTextBox1.Text = rd.Value.ToString
Catch ex As Exception
RichTextBox1.Clear()
RichTextBox1.Text = ex.ToString
Finally
If Not rd Is Nothing Then
rd.Dispose()
rd = Nothing
End If
End Try
Ctrl.Logoff()

End Sub

 

/Ari.

Do you have to logon to the controller both for Reading and writing values to controller? In the samples in RAB 5.09 manual no login is done for reading... I think that ABB should check the samples so they really work. Couse it will be a really good help to beginners.

You dont need to take mastership, but you need to be logged on to the controller.
