   ' *******************************
   ' * set the value
   MyTag.Value = 1234
   {.. elsewhere in code...}
   
   ' *******************************
   ' * write value to PLC
   MyPLC.WriteTag(MyTag)
    
   ' *******************************
   ' * check the status
   If ResultCode.QUAL_GOOD = MyTag.QualityCode Then
      Console.WriteLine(MyTag.Timestamp.ToString())
   Else

   Console.WriteLine(MyTag.QualityString)
Catch ex As System.Exception
