I seem to have a similar problem on page 2 , only it doesn't seen to be polling the PLC at all. tried adding a 2nd PLC driver and that did not work,
Public Class Page2
'*******************************************************************************
'* Stop polling when the form is not visible in order to reduce communications
'*******************************************************************************
Private Sub Form_VisibleChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.VisibleChanged
If components IsNot Nothing Then
Dim drv As AdvancedHMIDrivers.IComComponent
'*****************************
'* Search for comm components
'*****************************
For i As Integer = 0 To components.Components.Count - 1
If components.Components(i).GetType.GetInterface("AdvancedHMIDrivers.IComComponent") IsNot Nothing Then
drv = components.Components.Item(i)
'* Stop/Start polling based on form visibility
drv.DisableSubscriptions = Not Me.Visible
End If
Next
End If
End Sub
Private Sub ReturnToMainButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MainForm.Show()
Me.Hide()
End Sub
Private Sub NumericSevenSegment1_Click(sender As System.Object, e As System.EventArgs) Handles NumericSevenSegment1.Click
End Sub
Private Sub Page2_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub NumericSevenSegment2_Click(sender As System.Object, e As System.EventArgs) Handles NumericSevenSegment2.Click
End Sub
End Class
