  • Page 115: Appendix D Programming The Watchdog Timer

    Programming the Watchdog Timer The PCM-5825 is equipped with a watchdog timer that resets the CPU or generates an interrupt if processing comes to a standstill for whatever reason. This feature ensures system reliability in industrial standalone or unmanned environments.

  • Page 116: Programming The Watchdog Timer

    You must write your program so that it writes 1 to I/O port 443 at an interval shorter than the timer's preset interval. The timer's intervals have a tolerance of ± 30%, so you should program an instruction that will refresh the timer about every second. PCM-5825 User's Manual...
