Function

Balanced operation and control performance: With a basic instruction execution efficiency of 0.064 μs per step, it can efficiently handle medium-scale logic programs, timing control, and batch data operations. It supports up to 128 PID loops (including self-tuning function), is suitable for mixed scenarios of discrete control and process control, and takes into account both control accuracy and response speed

Practical memory and data management: 64k step program memory + 512 KB data memory, meeting the requirements of conventional complex process parameter storage, variable management and fault log recording; The SD card expansion function can achieve program backup/recovery, data log export and multi-recipe switching, enhancing the convenience of system maintenance

Flexible I/O expansion and distributed networking: Up to 8192 local I/O points, capable of connecting digital quantities, analog quantities, and special function modules (such as high-speed counting, pulse output, thermocouple acquisition modules); Supports remote expansion of mainstream industrial networks, covering the multi-station and multi-area control requirements of small and medium-sized factory areas, and realizes centralized management and decentralized control

Multi-protocol integrated communication: Equipped with dual Ethernet + RS-485 interfaces, compatible with multiple industrial protocols, it can directly connect to HMI, SCADA, frequency converters, intelligent meters and other devices, completing basic networking without the need for additional communication modules. Support the expansion of third-party protocol modules to adapt to complex cross-system communication scenarios

High reliability and data protection: Built-in power-off retention capacitor, critical data (programs, PID parameters, counter values) can be retained for ≥10 days (optional Q6BAT battery backup module extends to several years). Industrial-grade anti-interference design, suitable for the electromagnetic interference environment in workshops, ensuring the stable operation of the system

Convenient maintenance and debugging: The multi-level fault diagnosis function can quickly locate the fault point (such as I/O module offline, communication link interruption). Support online program download and real-time parameter modification, allowing debugging and upgrading to be completed without shutting down the machine. The status indicator light provides intuitive feedback on the working status, reducing the difficulty of maintenance

Wide compatibility: Fully compatible with all I/O modules, communication modules and special function modules of Mitsubishi Q series, and can be linked with Q series motion control modules and process control modules. Supports networking and communication with FX series and L series PLCS, and is compatible with the integration and expansion scenarios of new and old systems

Application scenarios

Logic control and multi-station collaboration for small and medium-sized discrete manufacturing production lines: electronic component assembly lines, automotive parts processing lines, and food packaging lines, controlling equipment such as solenoid valves, contactors, and servo drivers to achieve process linkage and counting and sorting functions

Conventional process control scenarios: temperature/pressure/flow closed-loop control of small-scale chemical reaction vessels, pharmaceutical liquid preparation systems, and water treatment dosing equipment. Process parameters are collected through analog modules, and control signals are output to regulate the speed of valves and pump sets, stabilizing process indicators

General mechanical automation: Small and medium-sized injection molding machines (mold closing/injection/ejection timing + pressure control), printing machines (tension control and speed synchronization), auxiliary control of CNC machine tools (fixture clamping, coolant switch, workpiece conveying)

Warehousing and logistics systems: small and medium-sized stereoscopic warehouses (storage location management, stacker crane linkage control), logistics sorting lines (multi-channel sorting logic, barcode recognition linkage), conveyor line zoned start and stop and speed adjustment

Energy and infrastructure control: Auxiliary systems for small power stations (pump sets, valve control), industrial boilers (temperature/pressure regulation), and building automation systems (central air conditioning, water supply and drainage, lighting interlocking control) communicate with the upper computer SCADA via Modbus TCP

System upgrade and transformation: Replace traditional relay control or outdated PLC systems to build small and medium-sized automation systems; For the upgrade scenarios of the original Q series low-performance cpus (such as Q02 cpus), direct replacement can enhance computing power and expansion capabilities, and be compatible with the original I/O modules and programs
