    55D4B000Shared Variable Project ItemGets 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.Read/WriteNo
    55D4B001Write?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.Read/WriteNo
    55D4B002Show Timestamp?Gets or sets whether LabVIEW shows the timestamp terminal on a Shared Variable node.Read/WriteNo
    55D4B003Custom RuleRead/WriteNo
    55D4B004Relative ModeGets or sets whether the connection between a shared variable and a Shared Variable node is absolute, target-relative, or the default mode.Read/WriteNo
    55D4B005Show Timeout?Gets or sets whether LabVIEW shows the ms timeout input and timed out? output on a Shared Variable node.Read/WriteNo
    55D4B006Timeout Allowed?Returns whether a Shared Variable node supports a timeout period.Read OnlyNo
    55D4B00AAllow Read?Returns whether you can read data from variable bound to the Shared Variable node.Read OnlyNo
    55D4B00BAllow Write?Returns whether you can write data to the variable bound to the Shared Variable node.Read OnlyNo
    55D4B00CAllow Relative?Returns whether you can set the Shared Variable node to a target-relative connection with the variable.Read OnlyNo
    55D4B00DAllow Absolute?Returns whether you can set the Shared Variable node to an absolute connection with the variable.Read OnlyNo
    55D4B00EAllow Direct?Returns whether you can set the Shared Variable node to use direct access.Read OnlyNo
    55D4B00FAllow Scanned?Returns whether you can set the Shared Variable node to use scanned access.Read OnlyNo
