Data Subscriber Question

[ENA]

See if this code works for you:

Code: [Select]

        Try
            Dim Result As Integer
            If Integer.TryParse(e.Values(0), Result) Then
                GlobalVariables.cs_tel = ((Result And 1) > 0)
            Else()
                MsgBox("Error in value " & v)
            End If
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try


Thank you Archie.

I modified my code similar to the way you suggested and it works, application continues to work normally. Also, your code suggestion is a bit more elegant than my old code.

However, there is now a new problem, I believe unrelated to data subscriber.

The setup is: two Micrologix 1400 and a PC connected via ethernet. Every PLC has a its own driver in PC application. My test was, what happens when I physically disconnect the cable connecting one PLC. First thing was, I got the error, which we now resolved. But now, when I reconnect the cable to the PLC, it seems that ethernet driver doesn't reconnect with that PLC and communication between PC and PLC cannot be continued.

Based on my testing of version 3.80 the extra Data Changed event that caused the double entries is now fixed.
Congratulations on a Job Well Done.

Thanks for giving us Advanced HMI.
