What leads you to believe that the client connection is not terminated?

Have you tried the same with recent Kepware server version?

Regards

Hi

I have a small VB6 app using a public function to read (see below) and write values to PLC via kepware.

Problem is when I exit the app, it will not terminate any client connection that it has created.

On subsequent restarts the client connection keeps getting bigger.

How do I kill all client connections when exiting the app.

Regards

Bill

    On Error GoTo ErrorRoutine
     ' Create EasyOPC-DA component
    Dim Client As New EasyDAClient
 
    ' Read item value and display it
    ReadValue = Client.ReadItemValue("", "KEPWare.KEPServerEx.V4", TextString)
    'Set Client = Nothing
 
    '
Exit Function
ErrorRoutine:
    'Call LogError("ReadValue", Err.Description)
    'Set Client = Nothing
End Function
