<![CDATA[Accessing OPC UA historical data]]>Hello,
I need to get the historical data of some OPC UA node, for example to retrieve all the data changes after a disconnection.
I'm not sure that this feature is impemented in the open62541 plugin that I use in QT.
Can anybody help me to understand if is it possible and how?

Im not sure the Qt plugin has any access functions for it nor that the version used have
this feature.
Its seems pretty new.
