VB for WinCC question

VB for WinCC question

VB for WinCC question

(OP)
Hi there,

I'm relative new to VB, I got a small problem. I'm using WinCC with VBS, it's something like VBA in excel.

I've got one variable called Dummy, this var can contain three conditions namely 1,2 and 4. If it contains 1 then a tekst (Press 3)should be displayed in var Test and so on.
In fact it's a selection of 3 radio buttons, it depends on which button is clicked which tekst should be displayed.

I wrote the following code

Sub OnLButtonDown(ByVal Item, ByVal Flags, By Val x, By Val y)

Dim dummy, Test

Set Dummy = HMIRuntime.Tags(“Dummy”)
Set Test = HMIRuntime.Tags(“Test”)

If Dummy = 1 Then Test = (“Pers3”)
    Else
        If Dummy = 2 Then Test = (“Pers4”)
        Else Test = (“Pers5”)
    End IF
End IF
End Sub

What am I doing wrong ?

RE: VB for WinCC question

Have you defined the variables in the appropriate section in WinCC?

' WINCC:TAGNAME_SECTION_START
Const TagNameInAction = "Dummy"
Const TagNameInAction = "Test"
' WINCC:TAGNAME_SECTION_END

RE: VB for WinCC question

I imagine you have solved this problem by now.  In the event you haven't, here is something, I believe, that will give you a step in the right direction:

Sub OnObjectChanged(ByVal Item)
Dim objTag
Dim selbutton
Dim buttonval

Set objTag = ScreenItems ("IOField4")


Set buttonval = ScreenItems ("OptionGroup1")
selbutton = buttonval.process
If selbutton = 1 Then
    objTag.OutputValue  = "Press 1"
    Elseif    selbutton = 2 Then
    objTag.OutputValue = "Press 2"
    Elseif    selbutton = 4 Then
    objTag.OutputValue = "Press 3"
    Else
    objTag.OutputValue = "Just here"
    End If

End Sub

I am running WinCC v6.0 and have worked with it since v4.  The VB scripting is a bit new to me but I'm playing with it.

Hi SiemensPLCguy,

Indeed I already solved the problem but thanks anyway. Perhaps I can help you in the future.
