Participating in the finals of the national competition for the first time, I had heard that the finals would feature some topics related to industrial control and the Internet of Vehicles. I also had a rough understanding of PWN topics involving the MQTT protocol and had used the Python Paho library for client interaction. However, … Read more
“PLC Data Encryption: AES Technology Reduces Transmission Risks by 99%, So You Can Rest Easy!” (Suspense Opening) For those in industrial control, have you ever encountered strange incidents where devices suddenly malfunction or data is inexplicably tampered with? It’s like your PLC and inverter suddenly breaking up, causing a collective strike of equipment and bringing … Read more
IntroductionIn PLC learning, many people fall into the trap of “piling up instructions”—memorizing the usage of timers and counters but unable to create a stable quiz buzzer. In fact, the quiz buzzer seems simple but hides the core logic of industrial control:signal priority judgment, interlocking to prevent conflicts, and state reset management. Today, we will … Read more
