vb.net - VB控制PLC的应用

Question

我试图使用来自Allen Bradley的vHMIABE驱动程序从Vb应用程序控制Allen Bradley ControlLogix PLC，但我不断收到此错误:

当我单击使用以下代码的“连接”按钮时，将出现此错误:

    Private Sub PLC_Connect_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PLC_Connect.Click

    'Connection to PLC
    Display.Items.Clear()

    With Read_Bit
        .Control_PLCType = vHMIABE.enuPLCType.ControlLogix 'PLC of ControlLogix
        .Control_PLCIPAddress = "192.168.1.112"
        .Control_SocketNumber = 44818
        .Control_ResponseTimeOut = 5000 'The communication will timeout after 5 secondes
        .Memory_Function = vHMIABE.enuPLCMemoryFunction.Connect ' Connection

        .Control_UseAdvancedErrorReporting = True 'Description of error messages

        .Control_Update() ' Make the connection

    End With

    With Write_Bit

        .Control_PLCType = vHMIABE.enuPLCType.ControlLogix 'PLC of ControlLogix
        .Control_PLCIPAddress = "192.168.1.112"
        .Control_SocketNumber = 44818
        .Control_ResponseTimeOut = 5000 'The communication will timeout after 5 secondes
        .Memory_Function = vHMIABE.enuPLCMemoryFunction.Connect ' Connection

        .Control_UseAdvancedErrorReporting = True 'Description of error messages

        .Control_Update() ' Make the connection

    End With

End Sub

我试图尽可能多地添加注释，以使我的代码更易于理解

有人有什么想法吗？

非常感谢每个前进。

我不知道该驱动程序，但是我可以为您提供一个基于.NET的更现代的选项，它更易于使用。实际上，一行代码将写入或读取变量
