Considerations
Considerations for user WDT (user watchdog timer)
User WDT error occurrence
If a user WDT cannot be reset due to a user program runaway, a user WDT error will occur.
In this case, take the following corrective actions.
• Increase the user WDT period set with the CCPU_StartWDT function.
• Lower the number of tasks with high CPU utilization or make them deactivated.
• Review the user program.
Reset the C Controller module once the corrective actions have been taken.
In the user program, a user WDT can be used to monitor the hardware and status of user program, and
processing timeout for accessing and controlling each module.
User WDT setting range
The user WDT period can be set within the range of 100 ms to 10,000 ms.
Output when a user WDT error occurs
When a user WDT error occurs, the output turns OFF.
