Function

High-end redundancy fault-tolerant control: Supports hot standby redundancy architecture. When configured in pairs, it can achieve real-time synchronization of programs and data. Faulty cpus can be automatically switched without disturbance to avoid system downtime and meet the "zero interruption" control requirements in critical scenarios.

Ultimate computing and processing performance: A 32-bit high-performance core combined with a high-speed computing unit can quickly execute complex logic control, multi-variable closed-loop control, high-level mathematical operations, and massive data processing, meeting the real-time control requirements of large-scale automation systems.

Multi-protocol high-reliability communication: Equipped with dual-core communication interfaces of Ethernet and PROFIBUS DP, it supports redundant communication link design, enabling the construction of distributed control networks. It can stably connect remote I/O, intelligent instruments, frequency converters, SCADA systems, etc., ensuring no packet loss and low latency in data transmission.

Comprehensive expansion and compatibility: Compatible with all Series 90-70 modules, supports multi-backplane expansion and cross-regional distributed deployment, can be flexibly expanded according to project scale, and is adaptable to various scenarios ranging from large single equipment to cross-factory collaborative control.

Comprehensive fault diagnosis and protection: It is equipped with self-diagnosis functions for faults in all dimensions such as CPU status, communication links, I/O modules, and power supplies, and provides intuitive feedback of fault information through LED indicator lights and software logs. Supports program backup/recovery, password access control, and memory key switch protection to ensure system security and data integrity.

Information integration capability: Supports communication with MES/ERP systems, capable of uploading production data, equipment status, fault records and other information, achieving production process traceability, remote monitoring and operation and maintenance management, and meeting the information requirements of Industry 4.0.
