-Rich storage configuration equipped with large capacity high-speed cache (L1/L2 Cache) reduces data access latency, provides expandable memory slots (supporting SDRAM) and non-volatile storage (such as Flash ROM), can store operating systems, control programs, and historical data, meeting storage needs in different scenarios.

-Multi dimensional communication interface integrates multiple industrial communication interfaces, including Ethernet (RJ45, supporting TCP/IP, UDP and other protocols), serial communication port (RS232/RS485, compatible with Modbus and other protocols), VME bus interface and N-bus dedicated interface, which can flexibly connect to industrial Ethernet, field bus and various I/O devices to achieve system interconnection and intercommunication.

-Industrial grade anti-interference and stability adopt enhanced electromagnetic compatibility (EMC) design, which complies with the IEC 61000-4 series anti-interference standards and can effectively resist electromagnetic radiation and pulse interference in industrial sites; Wide temperature working range (-40 ℃~70 ℃ typical value) is suitable for extreme high and low temperature environments, ensuring continuous and stable operation under harsh working conditions.

-Complete fault diagnosis and fault-tolerant built-in hardware watchdog timer, which can automatically restart the system when the program is abnormal; Support backup and recovery of key parameters, equipped with status indicator lights (power, operation, fault, bus status, etc.) for quick location of hardware or communication faults.

-Modularity and scalability follow the modular design concept of VME bus, supporting parallel operation of multiple processors (through VME bus arbitration), and can expand I/O modules, communication modules, etc. according to system requirements, flexibly building control platforms of different scales.
