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