SharedVariableNode Properties Table

Property ID	Short Name (English)	Description	R/W	RTE
55D4B00D	AllowAbsolute?	Returns whether you can set the Shared Variable node to an absolute connection with the variable.	R
55D4B00E	AllowDirect?	Returns whether you can set the Shared Variable node to use direct access.	R
55D4B00A	AllowRead?	Returns whether you can read data from variable bound to the Shared Variable node.	R
55D4B00C	AllowRelative?	Returns whether you can set the Shared Variable node to a target-relative connection with the variable.	R
55D4B00F	AllowScanned?	Returns whether you can set the Shared Variable node to use scanned access.	R
55D4B00B	AllowWrite?	Returns whether you can write data to the variable bound to the Shared Variable node.	R
55D4B003	CustomRule		R/W
55D4B012	GetVRTILOErrors		R	X
55D4B010	IOVLocalAccessMode	Gets or sets the access mode of the Shared Variable node.	R/W
55D4B004	RelativeMode	Gets or sets whether the connection between a shared variable and a Shared Variable node is absolute, target-relative, or the default mode.	R/W
55D4B000	ProjectItem	Gets or sets a reference to the shared variable in the LabVIEW Project that is associated with a Shared Variable node. If the VI with the Shared Variable node is not part of a project, or if the shared variable is located in a different project than the VI, LabVIEW returns an error.	R/W
55D4B005	ShowTimeout?	Gets or sets whether LabVIEW shows the ms timeout input and timed out? output on a Shared Variable node.	R/W
55D4B002	ShowTimestamp?	Gets or sets whether LabVIEW shows the timestamp terminal on a Shared Variable node.	R/W
55D4B006	TimeoutAllowed?	Returns whether a Shared Variable node supports a timeout period. You only can enable a timeout period for Shared Variable nodes configured to read data. You cannot enable a timeout period for nodes that access I/O variables locally.	R
55D4B011	TimestampAllowed?	Returns whether LabVIEW can display a timestamp for a Shared Variable node. Timestamps are supported only by Shared Variable nodes that are configured to read data.	R
55D4B001	Write?	Gets or sets whether a Shared Variable node is configured to read or write data. TRUE corresponds to writing data, and FALSE corresponds to reading data.	R/W

SharedVariableNode Methods Table

Method ID	Short Name (English)	Description	RTE
55D4AC02	Change to Constant	Changes the shared variable node to a constant and returns a reference to the constant. LabVIEW automatically closes the reference to the shared variable node.
55D4AC00	Change to Control	Changes the shared variable node to a control and returns a reference to the control. LabVIEW automatically closes the reference to the shared variable node.
55D4AC01	Change to Indicator	Changes the shared variable node to an indicator and returns a reference to the indicator. LabVIEW automatically closes the reference to the shared variable node.
55D4AC03	CopyLinkageFromVarXNode
55D4AC04	MarkVIRelative
