Function

Ultimate processing performance: The basic instruction speed is 0.98ns, which is over 50% faster than that of mid-range cpus in the same series. The efficiency of complex instructions such as floating-point operations and string processing is outstanding. It can simultaneously handle large-scale logic control, data operations, and multi-device communication tasks without performance bottlenecks.

Ultra-large capacity storage: With a program capacity of 500K steps, it can meet the complex process logic of medium and large production lines (such as multi-process linkage and formula management). Equipped with 4MB standard RAM and 16MB expansion support, it can cache massive production data (such as historical trends and fault records) without the need for additional data modules.

Multi-protocol communication integration: Dual Gigabit Ethernet ports support link redundancy and load balancing, enhancing communication stability. Natively supports OPC UA and MQTT protocols, and can be directly connected to industrial Internet platforms (such as Mitsubishi iQ Cloud, third-party SCADA/MES systems) to achieve data migration to the cloud and remote monitoring. The RS-485 port is compatible with Modbus RTU, facilitating the connection of third-party devices such as frequency converters and sensors.

High reliability design: Built-in hardware watchdog, voltage monitoring, and self-diagnosis function for communication faults, which can automatically identify module abnormalities and trigger protection actions (such as maintaining output status and alarm output). Support program encryption (32-bit character password) and device access permission control to prevent unauthorized operations; Dual Ethernet ports support redundant communication to prevent system downtime caused by a single point of failure.

Intelligent data processing: Supports automatic data recording on SD cards (CSV format), and can store production parameters triggered by time and events. It has an inbuilt file processing function that can directly read/write CSV and TXT files, enabling data traceability without programming. Supports high-speed counters and pulse output (with a module), suitable for high-speed signal acquisition and control scenarios.

Multi-cpu collaborative expansion The 64K-byte multi-CPU high-speed communication area can be combined with Q series motion control cpus (such as Q25PRHCPU) and process control cpus to form a multi-CPU system. The communication cycle is as low as 0.5ms, achieving deep collaboration among sequential control, motion control, and process control. Meet the integrated control requirements of complex equipment (such as multi-axis linkage machine tools and automated production lines).

Application scenarios

Medium and large-scale automated production lines: automotive assembly lines, lithium battery electrode sheet production equipment, semiconductor packaging and testing lines, etc. They need to handle multi-process linkage, massive I/O control and multi-device collaboration. With a program capacity of 500K steps and high-speed processing capabilities, they can cover complex process logic.

In the field of process control: chemical reactor clusters, power boiler control systems, and water treatment plant automation systems. By combining analog modules, high-precision closed-loop control of parameters such as temperature, pressure, and flow is achieved. It supports OPC UA/MQTT protocol connection with upper-level monitoring systems to realize the visualization and remote adjustment of process parameters.

Intelligent factory data interaction: As the factory-level control core, it connects multiple PLCS, Hmis, robots, AGVs and other devices in the workshop. Through dual Ethernet ports, it realizes the summary of production data and the issuance of instructions, supporting the production scheduling and quality traceability functions of the MES system.

High-end single-machine equipment: large injection molding machines, high-speed printing machines, and multi-axis CNC machine tools, which need to handle logic control, motion control (with QD75 series motion modules), and equipment status monitoring simultaneously. High-speed processing and multiple communication interfaces can meet the high-precision and high-cycle operation requirements of the equipment.

Redundant control system: In scenarios with extremely high reliability requirements (such as auxiliary systems of nuclear power plants and key equipment in petrochemicals), through dual-CPU hot standby and dual-Ethernet redundant configuration, it ensures the stable operation of the system 24/7 and avoids production interruption caused by faults
