China has replaced the programmable logic controllers (PLCs) supplied by Siemens and Schneider Electric at the 13.86 GW Xiluodo Dam, replacing them with Chinese-made PLCs.

The change, announced by Loongson Technology , was said to be part of a national policy to strengthen critical infrastructure against cyber threats and reduce reliance on foreign suppliers. Loongson has announced that all foreign-made PLCs at Xiluodo had been replaced with the NJ400 series PLC, developed by Atekon Technology and powered by Loongson’s own 3C6000 processors.

Loongson said that the change: “Provides a solid technological base for long-term safe and stable operation using independent and controllable technology.”
