Sum PLC Tag Values in AHMI

[Rangers]

I would like to find the sum of tags in eight different PLCs and display the result using AHMI.  Each PLC has a daily output value that I would like to sum with the value of the remaining machines and display as "Line Output".  I am using 8 individual drivers to communicate to each PLC and display miscellaneous data for production using basic labels.  I have minimal experience with Visual Studio and have not been able to figure it out on my own.  Any help would be much appreciated. 

I know how to do this on the PLC side, but would rather accomplish it using AHMI, if possible.

One way to do this is the handle the ValueChanged Event for each BasicLabel. In that event add all the values and put it in another Label.

Similar to this:

Code: [Select]

    Private Sub BasicLabel3_ValueChanged(sender As Object, e As EventArgs) Handles BasicLabel1.ValueChanged, BasicLabel2.ValueChanged, BasicLabel3.ValueChanged
        Try
            Dim Sum As Integer = CInt(BasicLabel1.Value) + CInt(BasicLabel2.Value) + CInt(BasicLabel3.Value)
            Label1.Text = Sum
        Catch ex As Exception

        End Try
    End Sub

Archie,

This worked exactly how I wanted.  I ended up using this logic with a Timer to execute the code periodically since a machine cycle time takes several minutes.  Thanks again for the help.
