Hi betows,

This document shows how LabVIEW stores data in Memory. refer to the link below and see if it helps.

Probably too late now but if anyone else comes along later and sees this, it depends on which API you're using. If you use IO servers its configurable here: http://zone.ni.com/reference/en-XX/help/371618G-01/lvmve/dsc_adv_attributes_setting/ (first word low?)

If you're using one of the modbus APIs it returns raw registers and you need to set the byte order based on your device. LabVIEW is big endian by default but that doesn't matter much.
