Problem: What is the difference between a soft reboot and a hard reboot on a real-time FieldPoint controller? Solution: A soft reboot, by definition, is anything that uses only software to reboot the controller. Therefore, a soft reboot can be performed through the Reboot button in MAX or using the RT Reboot Controller.vi in LabVIEW (The LabVIEW Real-Time module must be installed on the Host PC to have access to the RT Reboot Controller.vi.). In a soft reboot, power is never removed from the controller. A hard reboot is defined as a reboot the removes power to the controller (i.e. pressing the Reboot button or unplugging the controller). The only technical difference is that a hard reboot will erase everything stored in RAM while a soft reboot will not. One cannot expect that things stored in RAM will be preserved after a soft reboot because RAM may be overwritten when the BIOS runs, and RAM will most likely not be allocated in the same way it was prior to the reboot.
