4.4.5.4 WatchDog timer

It is important in industrial applications that the control systems are rarely crashed, or are capable of self-reset if they are halted somehow. Watchdog function of automatic resetting system is therefore provided in SPC. There is a timer inside the watchdog function. User’s AP could invoke the associated APIs in Watchdog function to start the timer, then Watchdog function would repeat the countdown of the specified period of time to reboot the system if the user’s AP does not clear the timer in time periodically. The Watchdog function in the SPC provides eight different time intervals: 2 seconds, 5 seconds, 10 seconds, 30 seconds, 60 seconds, 2 minutes, 5 minutes and 10 minutes. The “Enable" button is used to simulate the Watchdog function. Detail programming guide is illustrated at section 4.7.5. The “Sleep” button could make the system enter suspend mode as “Suspend” of “Start” could. Press the "SoftReset" button will cause system warm boot that clears DRAM, reloads all drivers and refresh the newest registry settings. Press the “REBOOT” button will cause the system cold boot.
