I'm fairly new to intract with PI.

 

I'm using PI SDK, I can insert a value to a specific Tag, but I have no clue how to add an annotation to the value.

 

Here is the code I'm using:

 

    Sub InserePoint(ByVal TagName As String, ByVal value As Integer, ByVal dateApplique As DateTime)
        Dim mySDK As PISDK.PISDK
        Dim dt As New PITimeFormat
        Dim pt As PIPoint

        Dim MYPIServer As PISDK.Server


        'Create an instance of the SDK
        If mySDK Is Nothing Then mySDK = New PISDK.PISDK


        'Get the default server
        MYPIServer = mySDK.Servers.DefaultServer


        'Get an instance on the PI Point
        pt = MYPIServer.PIPoints(TagName)


         'Date applied
        dt.InputString = dateApplique


        'Insert value
        'This is where I'd like to add an annotation, say "Imported from such and such"
        pt.Data.UpdateValue(3, dt, DataMergeConstants.dmReplaceDuplicates)


    End Sub

 

What should I be doing to add an annotation to this value that I'm entering?
