Adding drivers programatically

[aquilmustafa]

Hi ,

I'd like to add the drivers programmatically while loading the Software could someone please guide me as to how that could be done.

This is in C# but how I do it. And i am connecting to an OPC Server

        AdvancedHMIDrivers.OpcDaCom opc = new AdvancedHMIDrivers.OpcDaCom();
        string OPCServerConn = "OPCServer";

        public void SetDemandPoints(string SetPoint, int SetValue)
        {
            try
            {
                opc = new AdvancedHMIDrivers.OpcDaCom();
                opc.OPCServer = OPCServerConn;
                opc.Write(SetPoint, Convert.ToString(SetValue));
            }
            catch
            {
                Console.WriteLine("Error on SetDemandPoints");
            }
                   
        }

hey,
thanks Mikefly95
could you please guide me as to how to do this in vb.net

[Mikefly95]

Something like this i would guess. Not an expert by any means.

    Dim CLX As New Drivers."DriverHere"

    Public Sub MainForm_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        CLX = New Drivers."DriverHere"
        CLX.ReadModifyWriteTag()

    End Sub

Someone may correct me.

Here is a little trick to learn how to create objects in code and ensure you have all of the supporting code with it:

- Start a new project as you normally do
- Add a driver to the form
- In Solution Explorer, at the top you will see an icon for Show All Files. Click that to enable it
- Now you should have an option to drill down into the MainForm
- Drill down into the MainForm.vb and look for MainForm.Designer.vb
- Right click Mainform.Designer.vb and select View Code
- Look for all the code associated to the driver instance

You will see something like this:

Declaring the object instance and adding to the components collection to ensure proper disposal

Code: [Select]

        Me.EthernetIPforSLCMicroCom1 = New AdvancedHMIDrivers.EthernetIPforSLCMicroCom(Me.components)

Setting the properties

Code: [Select]

        '
        'EthernetIPforSLCMicroCom1
        '
        Me.EthernetIPforSLCMicroCom1.CIPConnectionSize = 508
        Me.EthernetIPforSLCMicroCom1.DisableSubscriptions = False
        Me.EthernetIPforSLCMicroCom1.IniFileName = ""
        Me.EthernetIPforSLCMicroCom1.IniFileSection = Nothing
        Me.EthernetIPforSLCMicroCom1.IPAddress = "192.168.1.233"
        Me.EthernetIPforSLCMicroCom1.IsPLC5 = False
        Me.EthernetIPforSLCMicroCom1.PollRateOverride = 500
        Me.EthernetIPforSLCMicroCom1.Port = 44818
        Me.EthernetIPforSLCMicroCom1.Timeout = 5000

Declaring the variable as Friend Scope (You may use Private scope unless you refer to the driver from other forms)

Code: [Select]

    Friend WithEvents EthernetIPforSLCMicroCom1 As AdvancedHMIDrivers.EthernetIPforSLCMicroCom


Following this pattern will ensure you do everything necessary to properly create, setup, and dispose of the object.
