Issue Details

I started using LabVIEW Real-Time Module 2024 and my system is now restarting. What changed?

Solution

Beginning in LabVIEW Real-Time Module 2024, startup applications using the LabVIEW Real-Time module Watchdog Configure.vi with the disable watchdog on VI exit boolean set to false and the reset system boolean set to true should expect their system to reboot upon a watchdog expiration. This is a change from previous behavior, where a system would not reboot in these conditions.

Note: if the timeout value for the Watchdog Configure.vi is set to <25 seconds, a system could enter an infinite reboot scenario requiring a reformat.
