Implements UnifiedAutomation.UaBase.IEncodeable.

getset |
For each NodeToRead this parameter specifies a continuation point returned from a previous HistoryRead call, allowing the Client to continue that read from the last value received.
The HistoryRead is used to select an ordered sequence of historical values or events. A continuation point marks a point in that ordered sequence, such that the Server returns the subset of the sequence that follows that point.
A null value indicates that this parameter is not used.
This continuation point is described in more detail in Part 11 of the OPC UA Specification.

getset |
A QualifiedName that specifies the data encoding to be returned for the Value to be read.
See ReadValueId for a definition on how to specify the data encoding.
The parameter is ignored when reading history of Events.
|
getset |
This parameter is used to identify a single element of an array, or a single range of indexes for arrays.
If a range of elements is specified, the values are returned as a composite. The first element is identified by index 0 (zero).
This parameter is null if the value is not an array. However, if the value is an array, and this parameter is null, then all elements are to be included in the range.
|
getset |
The nodeId to be read depends on HistoryReadDetails.
If HistoryReadDetails is
If the Node does not support the requested access for historical values or historical events, the appropriate error response for the given node shall be generated.
