Описание методов

GetContiguousDataRegions() публичный статический Метод

Read historian data from server.

1 tick = 100 nanoseconds.

public static GetContiguousDataRegions ( Connection connection, System.DateTime startTime, System.DateTime stopTime, ulong measurementID, Resolution resolution, long expectedFullResolutionTicks = 333333 ) : DateTime>>.IEnumerable
connection	Connection	openHistorian connection.
startTime	System.DateTime	Start time of query.
stopTime	System.DateTime	Stop time of query.
measurementID	ulong	Measurement ID to test for data continuity.
resolution	Resolution	Resolution for testing data.
expectedFullResolutionTicks	long	Expected number of ticks per interval at full resolution, e.g., 33,333 = 1/30 of a second representing a sampling interval of 30 times per second.
Результат	DateTime>>.IEnumerable
