Watchdog Timer Function
Data may fail to be updated due to Modbus or other communication problems.
The watchdog timer function replaces values with their preset values or last values and when
values are not updated within the specified duration (timer).
Data replacement occurs immediately when the timer expires, and the values are held until the
next read cycle.
The watchdog timer is also useful for detecting communication interruptions caused by
communication errors.
