Allow Absolute?
Returns whether you can set the Shared Variable node to an absolute connection with the variable.
Allow Direct?
Returns whether you can set the Shared Variable node to use direct access.
Allow Read?
Returns whether you can read data from variable bound to the Shared Variable node.
Allow Relative?
Returns whether you can set the Shared Variable node to a target-relative connection with the variable.
Allow Scanned?
Returns whether you can set the Shared Variable node to use scanned access.
Allow Write?
Returns whether you can write data to the variable bound to the Shared Variable node.
IOVLocalAccessMode
Gets or sets the access mode of the Shared Variable node.
Relative Mode
Gets or sets whether the connection between a shared variable and a Shared Variable node is absolute, target-relative, or the default mode.
Shared Variable Project Item
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.
Show Timeout?
Gets or sets whether LabVIEW shows the ms timeout input and timed out? output on a Shared Variable node.
Show Timestamp?
Gets or sets whether LabVIEW shows the timestamp terminal on a Shared Variable node.
Timeout Allowed?
Returns whether a Shared Variable node supports a timeout period.
Timestamp Allowed?
Returns whether LabVIEW can display a timestamp for a Shared Variable node.
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.
