Hi,
I am using subscription to OPC UA and reading values from onDataChange call back method.
I want to understand difference between the status codes under MonitoredDataItem and DataValue.
1. Are monitoredDataItem.errorCode and dataValue.getStatusCode both same?
2. And where can we get the error code when we call client.readValue, because here we do get only DataValue response?
Thanks!

Hello,
1. The StatusCode provided by MonitoredDataItem.getErrorCode() contains error codes related to creation of the MonitoredItem and the StatusCode provided by DataValue.getStatusCode() describes the “quality” of the value.
2. The response of a Read operation doesn’t include separate error codes, but you can check the StatusCodes of the returned DataValues for errors related to Reading the values.
