How to read AnnotationData of UA HA
Posted: 12 Apr 2022, 07:41
Hi.
Please let me know how to implement UA client code in order to realize 'Read Annotation Data' written in 'OPC UA 1.04 Part11 Table 19 – HistoryReadDetails parameterTypeIds' by using UA SDK C++ Client.
If UA SDK C++ does not support such functionality, please let me know how to read Annotation Data from OPC UA HA Server by using UA SDK C++ Client. I guess that calling UaSession::historyReadRawModified with specifying the historyReadRawModifiedContext::isReadModified as true enables to read Annotation Data. Am I correct?
Thank you in advance.
Best regards,
