MX Component 使用控件通訊 就可以直接PLC內部地址的名字，不要在整個標簽。
標簽能了很久 還是不行。


****
控件有很多






感覺三菱每個可以通訊的硬件 都有一個對應的  控制可以使用

    

驗證通過AxActUtlTypeLib.AxActUtlType訪問Q04UDV的CPU，硬件接口為以太網
***
新建一個VB.net  ，窗口程序，在工具欄里面添加 控件
如下圖：

添加OPEN 和CLOSE函數

#Region "打開鏈接"
    Private Sub btn_Open_Click(sender As Object, e As EventArgs) Handles btn_Open.Click
        Dim iReturnCode As Integer              'Return code
        Dim iLogicalStationNumber As Integer    'LogicalStationNumber for ActUtlType

        ClearDisplay()

        Try
            If GetIntValue(txt_LogicalStationNumber, iLogicalStationNumber) = False Then
                'If failed, this process is end.
                Exit Sub
            End If
            AxActUtlType1.ActLogicalStationNumber = iLogicalStationNumber

            iReturnCode = AxActUtlType1.Open()

            If iReturnCode = 0 Then
                'When the Open method is succeeded, disable the TextBox of 'LogocalStationNumber'.
                txt_LogicalStationNumber.Enabled = False
            End If
        Catch exception As Exception
            MessageBox.Show(exception.Message, Name, MessageBoxButtons.OK, MessageBoxIcon.Error)
            Exit Sub

        End Try
        txt_ReturnCode.Text = String.Format("0x{0:x8} [HEX]", iReturnCode)
    End Sub
#End Region

**************
#Region "關閉鏈接"
    Private Sub btn_Close_Click(sender As Object, e As EventArgs) Handles btn_Close.Click
        Dim iReturnCode As Integer     'Return code
        ClearDisplay()


        Try
            iReturnCode = AxActUtlType1.Close()
            If iReturnCode = 0 Then
                txt_LogicalStationNumber.Enabled = True
            End If

        Catch exception As Exception
            MessageBox.Show(exception.Message, Name, MessageBoxButtons.OK, MessageBoxIcon.Error)


        End Try
        txt_ReturnCode.Text = String.Format("0x{0:x8} [HEX]", iReturnCode)
    End Sub
#End Region

測試可以通過
