Product Performance
1:1 hot redundancy architecture design, master and standby modules synchronize data in real time, realize disturbance-free switching in case of failure, switching time less than 1ms, ensuring continuity of production process.
32-bit RISC processor combined with high-speed control cycle can efficiently run thousands of PID control loops, meeting the real-time requirements of complex process control.
Large-capacity program and data memory support storing complex control logic and historical data, and local data caching can be realized without external storage devices.
Built-in multi-protocol communication interfaces can seamlessly connect with third-party PLC and SCADA systems, breaking the data interaction barrier of heterogeneous systems.
Integrated complete self-diagnosis function can real-time monitor module hardware, communication links and control program status, and fault information is quickly uploaded to the operation station.
Industrial-grade wide-temperature design and anti-electromagnetic interference capability enable long-term stable operation in industrial sites with strong interference and high dust, and the Mean Time Between Failures (MTBF) exceeds 100,000 hours.
Deeply compatible with Centum VP series I/O modules and communication modules, supporting online expansion and hot swapping, greatly reducing system maintenance downtime.
Supports function block programming and ladder diagram programming, meeting the programming habits of different engineers and shortening project development and debugging cycles.
