System shutdown feature

To avoid open files and FAT disk coherency issues that could affect system integrity in case of unexpected power-off, it is highly recommended to use this feature every time users turn off the system.Having indication that the user wants to turn off, the system automatically performs all the requested stopping, closing and shutdown operations in the best way.At the end of the shutdown process, the system either will be automatically turned off (only with hardware supporting this option), or a message will be displayed by the HMI to request the manual power-off to the user.Refer to GFB_SYS(616) for more information about the introduction of this feature in the application program.
