In the field of industrial control systems, autonomy and controllability have become the cornerstone of national security and industrial safety. Faced with an increasingly complex international environment, China urgently needs to overcome the “bottleneck” problem in its industrial control systems. The launch of the Hualisi LKC series PLC marks a solid step forward for China in the field of autonomous and controllable industrial control systems, providing a safe and reliable “Chinese core” for key national sectors.
100% Autonomous and Controllable, Strengthening the Safety Defense
The Hualisi LKC series PLC is based on years of PLC product R&D technology from Hualisi, fully incorporating the latest achievements in international industrial electronics and control technology, and developed in accordance with international advanced industrial standards, safety design standards, and reliability design standards. Its core breakthrough lies in achieving 100% autonomy and controllability: the network communication protocol stack, embedded software, and programming software are all independently developed, while the hardware uses the Loongson 2K1000 dual-core 1GHz high-performance industrial processor, achieving full-link autonomy and controllability from chip to system.
This groundbreaking achievement has passed multiple authoritative certifications, including Achilles Level 2 certification and network critical equipment security certification (GB40050), supporting trusted computing proactive protection, and establishing a solid defense for the safety of industrial control systems. In the current international situation, the launch of the LKC series PLC not only addresses the “bottleneck” problem but also provides reliable security for China’s industrial control systems.
