4.2.3Watchdog timer

It is important in industrial applications that the control systems are rarely down, or are capable of self-reset if they are halted somehow. The watchdog timer is therefore used in the TPC-1260 to provide automatic reset. There is a timer inside the watchdog timer. The TPC- 1260 should clear the timer within a pre-set time interval periodically. If the timer is not cleared, the timer would assume the system to be halted and generate a reset.

The watchdog timer in the TPC-1260 provides a fixed time interval: 1.6

seconds. As mentioned in the section 4.2.2: when the system boots, there is an icon “S” on the status bar. Tap this icon by a stylus for the setting window.

Select whichever time interval required, and tap one of the buttons: “OK”, “Cancel” or “Save”.

Notice:	Please be careful before selecting “Save”. This
	command will overwrite all registry data—not only the
	watchdog timer settings.
