The demo shows a ping-pong ball controlled by a fan and a top sensor, with both the ball position and HMI level moving as flow control changes. It then simulates a DCN1 failure by pulling network cables, after which DCN2 takes over seamlessly and the system continues operation. The video continues by gracefully shutting down DCN2, bringing it back online, and then restoring DCN1 so DCN1 becomes the follower while DCN2 remains the leader.
