PDA and Touch Panel VI Hierarchies (PDA Module, Touch Panel Module)
Design PDA and Touch Panel VIs with wide, shallow VI hierarchies. Nested VI calls use large amounts of memory and might cause the PDA or Touch Panel VI to fail. Wide, shallow hierarchies have only a few VIs running at any time and use less memory.
Because of the different application structure on PDA and Touch Panel targets, PDA and Touch Panel VIs always start from one top-level VI and exit when that top-level VI completes. This behavior is different from a typical LabVIEW for Windows application in which you can start and run multiple top-level VIs simultaneously.
