TwinCAT.Ads.SumCommand Namespace

ADS offers powerful and fast communication to exchange any kind of information. It's possible to read single variables or complete arrays and structures with each one single ADS-API call. ADS Sum-Commands offer to read/write with one single ADS call multiple variables which are not structured within a linear memory, effectively reducing roundtrips.

Classes

	Class	Description
	ISumCommandExtension	Extension class for ISumCommand derived classes.
	ResultSumCommand	Result class for an asynchronous TwinCAT.Ads.SumCommand:
	ResultSumHandles	Result class for an asynchronous SumCreateHandles>.
	ResultSumHandles2	Result class for an asynchronous SumCreateHandles.
	ResultSumReadRaw	Result class for an asynchronous SumRead that contains blocks of raw memory data (unmarshaled data).

	ResultSumValues2<S>	Extended result class for an asynchronous ISumRead2<S>.
	SumAnyTypeRead	Symbolic ADS Sum read access (ANY_TYPE marshalling) on already loaded symbols.
	SumCreateHandles	SumCommand for getting variable handles by a set of InstancePaths and using the Handles cache.
	SumCreateHandlesBase	SumCommandBase for getting variable handles by a set of InstancePaths
	SumDeleteNotifications	SumCommand for deleting Notifications.
	SumHandleReadAnyType	Read (primitive, AnyType) values by Handle SumCommandBase.
	SumHandleWriteAnyType	Write any (primitive) values by Handle SumCommandBase.
	SumHandleWriteRaw	Write any (primitive) values by Handle SumCommandBase.
	SumInstancePathAnyTypeRead	SumRead Command that uses the instancePath as symbol ID / Address and returns objects as Values (ANY Type marshaling)
	SumReleaseHandles	Release Handles SumCommand (internal)
	SumReleaseHandlesBase	Release Handles SumCommand (internal)
	SumSymbolRead	Symbolic ADS Sum read access (automatic marshalling)
	SumSymbolWrite	Class for ADS Sum symbolic Write Access.
	SumWriteBySymbolPath	SumCommand writing Anytypes values by Instance path
