Using the cRIO-9030 File System
The file system of the cRIO-9030 follows conventions established for UNIX-style operating
systems. Other LabVIEW Real-Time targets follow Microsoft Windows-style conventions. In
order to facilitate the porting of applications from those targets, this target supports the
Windows-style
/C home directory. This path is bound to the UNIX-style directory
/home/lvuser.
Various LabVIEW Real-Time system files which would be accessible from C: (or /C) on other
LabVIEW Real-Time targets are found in different locations on this target.
UNIX-style file systems support the concept of a symbolic link, which allows access to a file
using an alternative file path. For example, it is possible to link
/C/ni-rt/system, where
dynamic libraries are deployed on other LabVIEW Real-Time targets, to
/usr/local/lib,
where they are stored on the cRIO-9030, if the application requires this.
For more information, go to
ni.com/info and enter the Info Code RT_Paths.
Using the Internal Real-Time Clock
The system clock of the cRIO-9030 is synchronized with the internal high-precision real-time
clock at startup. This synchronization provides timestamp data to the controller. You can also
use the internal real-time clock to correct drift of the system clock. Refer to the Internal
Real-Time Clock section for the accuracy specifications of the real-time clock.
