MX Component 使用控件通讯 就可以直接PLC内部地址的名字，不要在整个标签。
标签能了很久 还是不行。


****
控件有很多






感觉三菱每个可以通讯的硬件 都有一个对应的  控制可以使用

    

验证通过AxActUtlTypeLib.AxActUtlType访问Q04UDV的CPU，硬件接口为以太网
***
新建一个VB.net  ，窗口程序，在工具栏里面添加 控件
如下图：

添加OPEN 和CLOSE函数

#Region "打开链接"
    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 "关闭链接"
    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

测试可以通过

随机读取

            Exit Sub
        End If

        ReDim sharrDeviceValue(iNumberOfDeviceName - 1)

        Try
            iReturnCode = AxActUtlType1.ReadDeviceRandom2(szDeviceName,  iNumberOfDeviceName, sharrDeviceValue(0))
        Catch exException As Exception
