Which malfunction typically results when PLC watchdog timers are improperly configured in automated robotic assembly lines?

💡 Explanation

Improper PLC watchdog timer settings cause a failure to reset the PLC’s program execution loop; thus, the system enters an error state. Because the machine stops rather than behaving erroneously, spurious activation or localized overheating are not direct results; therefore 'machine stall' is correct.
