Data Quality Issues - OPCLabs client and Softing's OPC server - by: bojan

Hi OpcLabs,
We have an issue with data quality. It appears that the data sent from OPCLabs client to Softing’s I-Nat server isn’t recorded in the server.
  • We send the data using DA: client.WriteMultipleItemValues(IList<DAItemValueArguments> writeArgs.ToArray())
  • We check the results of sending using: operationResult.Succeeded of every result item
  • All elements in result set have this flag as true.
  • In rare occasions (e.g. 1 out of 700 items) some of the item has the different value in OPC server from what we sent.

How can we address this issue?
We created an app using OPCLabs component, so we can verify where the discrepancy is and are also monitoring the changes. The discrepancy is there already after the initial push.
