Syntax

C#

public interface ISumRead2<S> : ISumCommand

Type Parameters

The ISumRead2S type exposes the following members.

Properties

	Name	Description
	Capabilities	Gets the capabilities. (Inherited from ISumCommand)
	Connection	The connection used for communication. (Inherited from ISumCommand)
	Count	Gets the number of the overall SubCommands. (Inherited from ISumCommand)
	Duration	Last Execution duration of the SumCommand (Inherited from ISumCommand)
	ErrorStrategy	Gets the error strategy of the ISumCommand (Inherited from ISumCommand)
	Executed	Gets a value indicating whether this ISumCommand was already executed. (Inherited from ISumCommand)
	ExecutedAsSum	Gets a value indicating whether the command has executed as SumCommand and not in Discrete mode (Inherited from ISumCommand)
	ExecutedDiscrete	Gets a value indicating whether the command has executed as Fallback/Discrete (Inherited from ISumCommand)
	Failed	Gets a value indicating whether this ISumCommand failed. (Inherited from ISumCommand)
	FailedCount	Gets the count of failed subcommands. (Inherited from ISumCommand)
	FallbackMode	Gets the fallback mode. (Inherited from ISumCommand)
	IsFallback	Gets a value indicating whether the SumCommand is in Fallback state. (Inherited from ISumCommand)
	Result	Gets the AdsErrorCode of the main SumCommandBase ADS Request (Inherited from ISumCommand)
	SubResults	Gets the sub results of the single Sub Requests. (Inherited from ISumCommand)
	Succeeded	Gets a value indicating whether this ISumCommand is succeeded. (Inherited from ISumCommand)
	SucceededCount	Gets the count of succeeded subcommands. (Inherited from ISumCommand)

Methods

	Name	Description
	Read2	Reads the Values.
	Read2Async	Reads Symbol values as an asynchronous operation.

Extension Methods

	Name	Description
	AllFailed	Gets a value indicating, that all SubCommands failed. (Defined by ISumCommandExtension)
	AllSucceeded	Gets a value indicating, that all SubCommands succeeded. (Defined by ISumCommandExtension)
	FirstSubError	Gets the first SubError that is not NoError (Defined by ISumCommandExtension)
	OneFailed	Gets a value indicating, whether the overall Sumcommand failed (checking all subcommand results). (Defined by ISumCommandExtension)
	OneSucceeded	Gets a value indicating, whether the overall SumCommand succeeded (including all subcommands) (Defined by ISumCommandExtension)
	OverallError	Gets the Overall (combined error) from SumCommand AND SubCommands. (Defined by ISumCommandExtension)
	PollValues2S	Polls a series of symbols via a ISumRead2S command. The SumCommand will read all contained values with every trigger in one roundtrip. (Defined by ValueSymbolExtensions)
	PollValues2S	Polls a series of symbols via a ISumRead2S command. The SumCommand will read all contained values with every trigger. (Defined by ValueSymbolExtensions)

Remarks

Implementations of this interface return enriched SubResults on SumCommand Reads, that include the original sourceId in its result to backtrace.
