Which outcome occurs when PLC sensor signal jitter exceeds watchdog timer threshold, controlling a robotic arm?

💡 Explanation

Activating an emergency stop is triggered by watchdog timer expiry due to signal jitter on the sensor; because the PLC initiates an emergency stop sequence rather than enabling continued operation; therefore preventing potential collisions or damage, rather than enabling movement.
