The secret to the success of China's PLC control cabinet industry in the past decade lies in the four-dimensional collaborative breakthrough of 'technological independence, intelligent integration, standard upgrading, and deep cultivation of scenarios'. Under the wave of domestic substitution, companies such as Huichuan, Zhongkong, and Hollysys have achieved full stack self-developed core controllers, redundant architectures, and industrial protocols (Profinet/EtherCAT). By 2025, the localization rate of large and medium-sized PLCs has reached 18.8%, and they are replacing foreign products in key fields such as new energy, chemical industry, and steel in bulk. The control cabinet has been fully upgraded to an 'edge intelligent node', integrating a lightweight AI inference engine to achieve motor vibration analysis, electrode life prediction, and fault prediction, reducing operation and maintenance costs by more than 30%. The modular hot swappable design supports flexible expansion of IO, communication, and power units, and the IP65 protection level has become a standard for harsh industrial scenarios such as dust, high humidity, and strong electromagnetic interference, ensuring stable operation 24/7. The unified technical specifications of 'Made in China 2025' and the new national standard GB/T 15969.2-2024 in 2024 will promote the industry to shift from 'imitation following' to 'standard leading'. At present, the control cabinet has evolved from a single execution unit to a closed-loop center of 'perception decision control', supporting the transition of intelligent manufacturing to flexibility and unmanned.
