Issue Details

  • I have a VI in LabVIEW where I make extensive use of stacked sequence structures.  I would like to migrate this VI to LabVIEW NXG 2.0, but I do not see a stacked sequence structure diagram in the palette.  How do I make use of stacked sequence structures in LabVIEW NXG 2.0?
  • When I migrated a VI from LabVIEW to LabVIEW NXG 2.0 using the Code Conversion Utility, I received a StackedSequenceReplacedByFlatSequence conversion message.


LabVIEW NXG 2.0 does not have stacked sequence structures.  If you migrate a VI that uses stacked sequence structures, it will be replaced with flat sequence structures, as described in the LabVIEW NXG 2.0 manual regarding the StackedSequenceReplacedByFlatSequence message.

Additional Information

You may find yourself able to make your code take up less space on the block diagram and still meet the same data flow dependency requirements by placing flat sequence structures into subVIs.
