Variant Data (PDA Module, Touch Panel Module)
Variant data does not conform to a specific data type and can contain attributes. LabVIEW represents variant data with the variant data type.
You cannot initialize variant data with default data in a PDA or Touch Panel VI. Placing a control, indicator, or constant that contains default data on the block diagram of the PDA or Touch Panel VI results in an empty LabVIEW variant.
