Property Documentation

byte [] UnifiedAutomation.UaBase.HistoryReadResult.ContinuationPoint
getset

This parameter is used only if the number of values to be returned is too large to be returned in a single response or if the timeout provided as hint by the Client is close to expiring and not all nodes have been processed.

If this parameter is not used, its value is null.

Servers shall support at least one continuation point per Session. Servers specify a maximum number of history continuation points per Session in the Server capabilities object defined in Part 5 of the OPC UA specification. A continuation point shall remain active until the Client passes the continuation point to HistoryRead or the Session is closed. If the maximum number of continuation points have been reached, the oldest continuation point shall be reset.

ExtensionObject UnifiedAutomation.UaBase.HistoryReadResult.HistoryData
getset

The history data returned for the node.

The HistoryData parameter type is an extensible parameter type formally defined in Part 11 of the OPC UA Specification. It specifies the types of history data that can be returned.

StatusCode UnifiedAutomation.UaBase.HistoryReadResult.StatusCode
getset

StatusCode for the nodesToRead item.
