OpcUa_Boolean UaClientSdk::HistoryReadRawModifiedContext::bReleaseContinuationPoints |
This parameter must be set to true to release a continuation point without requesting more data.
The default value is false.
UaDateTime UaClientSdk::HistoryReadRawModifiedContext::endTime |
The end time of the requested time domain.
The values can be read in inverse order if the end time is before the start time. The default value is null.
OpcUa_Boolean UaClientSdk::HistoryReadRawModifiedContext::isReadModified |
Indicates if modified data should be read instead of the raw data.
The default value is false.
OpcUa_UInt32 UaClientSdk::HistoryReadRawModifiedContext::numValuesPerNode |
Parameter to limit the number of results per node.
A server can further limit the number he returns. If the client or server limit exceeds the number of results available, a continuation point is returned in the history read response. The default value is 0.
OpcUa_Boolean UaClientSdk::HistoryReadRawModifiedContext::returnBounds |
Indicates if bounding values should be returned.
Bounding values are delivered if this flag is set to true and no value is available for the requested start or end time. The default value is false.
UaDateTime UaClientSdk::HistoryReadRawModifiedContext::startTime |
The start time of the requested time domain.
The values can be read in inverse order if the end time is before the start time. The default value is null.
OpcUa_TimestampsToReturn UaClientSdk::HistoryReadRawModifiedContext::timeStamps |
Enumeration for the timestamps to return with the values.
The default value is Source.
Possible options are
The option OpcUa_TimestampsToReturn_Neither = 3 is invalid for history read.
