FeedbackNode Properties Table

Property ID	Short Name (English)	Description	R/W	RTE
778ED406	Delay	Gets or sets the value of the Feedback Node delay. If the delay is less than 1, LabVIEW returns an error.	R/W	X
778ED400	Dir	Gets and sets the direction the Feedback Node faces.	R/W
778ED40B	DisconnectEnable		R/W	X
778ED407	EnableTerm?	Gets or sets whether the enable terminal of the Feedback Node is shown.	R/W	X
778ED409	Header	Gets or sets the cosmetic appearance of the Feedback Node. Using this property to set the appearance is similar to right-clicking a Feedback Node and enabling or disabling the Z-Transform View item in the shortcut menu.	R/W	X
778ED40A	IgnoreReset	Gets or sets whether this Feedback Node initializes if the FPGA VI resets. If TRUE, this node does not initialize if the FPGA VI resets. This node initializes the next time you download the FPGA VI to the FPGA target. This property applies only when the Feedback Node is deployed on an FPGA target. This property can have a value of TRUE only when the initialization style of the Feedback Node is to initialize on compile or load. If you write a value of TRUE, ensure the application does not depend on the value this Feedback Node returns on the first call after resetting the FPGA VI.	R/W	X
778ED40C	InitMuxLocation	Controls where the initialization multiplexer is relative to the core feedback register when the containing VI is targeted to FPGA. The multiplexer can only be before the register if a constant is wired in to the initialization terminal. This option only applies if the feedback node is globally initialized.	R/W	X
778ED408	InitType	Places the initializer terminal on the innermost loop. When you first call this method, or when LabVIEW compiles or loads the VI that contains the loop, LabVIEW places the terminal on the node and sets the initialization mode appropriately.	R/W	X
778ED405	InitOnLoop	Returns TRUE if the initializer terminal of the Feedback Node is on a loop and not globally initialized on the first call of the VI in an execution or when the VI it belongs to compiles or loads.	R
778ED403	InitTerm	Returns a reference to the initializer terminal of the Feedback Node.	R
778ED404	InitializersLoop	Gets or sets a reference to the loop to which the initializer is currently attached, or an invalid reference if the initializer is not on a loop and will be globally initialized.	R/W
778ED402	InputTerm	Returns a reference to the input terminal of the Feedback Node. The input terminal of a Feedback Node provides the output value for the node the next time the VI runs.	R
778ED401	OutputTerm	Returns a reference to the output terminal of the Feedback Node.	R

FeedbackNode Methods Table

Method ID	Short Name (English)	Description	RTE
778ED001	HighlightInit	Scrolls to and highlights the initializer of the Feedback Node. To perform the same action with the rest of the Feedback Node, use the Object Highlight method.
778ED000	RepWithShiftReg	Changes a Feedback Node inside a loop into a shift register. LabVIEW returns an error if the Feedback Node is not within a loop. If the Feedback Node initializer terminal is on a loop, LabVIEW adds the shift register to that loop. If the initializer terminal is not on a loop, LabVIEW adds the shift register to the innermost loop that contains the Feedback Node. Note After this method executes, the reference to the Feedback Node is no longer valid.
