Can you please describe what "loses connection to the tags" mean? Is that broken connection between the OPC Server and the target device, or (if not), what kind of lost connection are we talking about?

When it loses connection to the tags it just displays the last received data until it regains connection to the tags, what I want it to do is to display "Bad" under quality if it can't connect to the tags

I do not understand what you mean by "is not working". Describe what it does, in your case, and what you expect it to do.

If attributeDataResult.Exception Is Nothing Then
row.Item("Quality") = attributeDataResult.AttributeData.StatusCode
Else
row.Item("Quality") = "Bad"
End If

This code doesn't appear to be working is there something that I'm missing?

That was all I had, I was not aware of the Exception method. Would you be able to point me to some documentation for it?

I need more code around this. Do you test attributeData.Exception ?

row.Item("Quality") = attributeDataResult.AttributeData.StatusCode


This is how I process them and it just stops on the last received data if connection is lost

As I wrote, that's not how it is supposed to work. If you are seeing different results and want us to look at it, you need to provide the details.

I'm just wondering as to why the DA side of the API will return a bad quality code when it is unable to connect to the tags while the UA side just displays the last received data
