In this case, the corresponding output values (xDone, xError, iError) are present at the outputs for exactly one cycle.	ETrigA
	xAbort	BOOL		TRUE: Action is stopped immediately and all outputs are reset to their initial values.	ETrigA
Output	xDone	BOOL		TRUE: Action successfully completed	ETrigA
	xBusy	BOOL		TRUE: Function block active	ETrigA
	xError	BOOL		TRUE: Error occurred, function block aborts action FALSE: No error	ETrigA
	xAborted	BOOL		TRUE : Action aborted by user	ETrigA
