SAFE MODE switch determines whether the embedded LabVIEW
Real-Time engine launches at startup. If the switch is in the OFF
position, the LabVIEW Real-Time engine launches. If the switch is in the
ON position at startup, the cDAQ controller launches only the essential
services required for updating its configuration and installing software.
The LabVIEW Real-Time engine does not launch.
If the software on the controller is corrupted, you must put the controller
into safe mode and reformat the controller drive. You can put the
controller into safe mode by powering it up either with the SAFE MODE
switch in the ON position or with no software installed on the drive.
Refer to the Measurement & Automation Explorer Help for more
information about installing software on the controller and reformatting
the drive on the controller.
Keep the SAFE MODE switch in the OFF position during normal
