Find a solution: first use SET_RTC to set the internal clock time of the PLC to the correct value, then use READ_RTC to read that time. Compare the value read with the value that was set; if they are equal, activate the output terminal to trigger the bell sound. Set a timing period for this activation (for example, 10 seconds, which is the duration for which the bell will sound), and once that time has passed, reset the output terminal again
What about networking PLCs from different brands?
It’s best to include a clock server, so that in case of problems, the time remains consistent
