10 \inmodule QtOpcUa
11 \brief This class stores the necessary information to request historic data from a server.
12 \since 6.3
13
14 This is the Qt OPC UA representation for the OPC UA ReadRawModifiedDetails for reading historical data
15 defined in \l {https://reference.opcfoundation.org/Core/Part11/v104/docs/6.4.3} {OPC UA 1.04 part 11, 6.4.3}.
16
17 When requesting historic data from a server, several values need to be provided to the server
18 to know which data to collect. The QOpcUaHistoryReadRawRequest class provides the required values.
19 \a startTimestamp and \a endTimestamp define the timerange where historic data should be collected from.
20 \a nodesToRead defines from which nodes historic data should be collected.
21 \a numValuesPerNode defines the maximum number of data values that should be returned per node.
22 \a returnBounds defines if the bounding values should be included in the result.
