7.2.12.2.7 PRU-ICSS IEP WatchDog

In industrial ethernet applications, the watchdog timer (WD) is used to monitor process data communication and to turn off the outputs of the digital input/output (DIGIO) functional block after a set time. The WD will thereby protect the system from errors or faults by timeout or expiration. The expiration is used to initiate corrective action in order to keep the system in a safe state and restore normal operation based on configuration. Therefore, if the system is stable, the watchdog timer should be regularly reset or cleared to avoid timeout or expiration.

The IEP watchdog timer supports the following features:

  • One 16-bit pre-divider for generating a WD clock (default 100μs) based on PRU_ICSS_IEP_CLK input
  • Two 16-bit Watchdog Timers:
    • PDI_WD for Sync Managers WD, used in conjunction with digital input/output (DIGIO)
    • PD_WD for data link layer user WD, used in conjunction with data link layer or application layer interface actions
Note:

For more details on the PRU-ICSS Industrial Ethernet Watchdog timer, refer also to the Watchdog timer register descriptions covered in the PRU_ICSS_IEP chapter of the Register Addendum.
