MR-J2S-500A MITSUBISHI Processor module

Product  Description：

Mitsubishi Electric Processor Modules, commonly known as CPU modules, are the central intelligence of the MELSEC Programmable Logic Controller (PLC) systems. These modules execute the control logic, process complex mathematical calculations, and manage communication across the entire automation network. From the compact FX series to the high-end iQ-R series, these processors are designed to handle everything from simple machine timing to sophisticated multi-axis motion and large-scale process control.

Product Parameters

The performance and capability of a Mitsubishi Processor Module are determined by its core architecture and memory specifications:

• Execution Speed: High-speed processing with basic instruction speeds often reaching 0.9 nanoseconds to 0.12 microseconds per step.

• Program Capacity: Ranges from 10k steps for small-scale applications up to 1200k steps or more for large integrated systems.

• Device Memory: Large internal memory for bit devices (relays) and word devices (registers), often expandable via SD memory cards.

• Multi-CPU Capability: Support for multi-processor configurations where up to four CPUs can be mounted on a single base unit to share tasks.

• Built-in Interfaces: Standard integration of Ethernet (up to 1 Gbps), USB for programming, and sometimes specialized motion or serial ports.

• Redundancy Support: Specific "R" series processors support redundant system architectures to ensure zero downtime in critical infrastructure.

Product Advantages

Mitsubishi Processor Modules are engineered to provide a balance of high-speed performance and industrial-grade stability:

• High-Speed System Bus: The internal backplane communication speed is significantly optimized, reducing the latency between the processor and I/O or motion modules.

• Integrated Security: Includes hardware-based security keys and IP filter functions to prevent unauthorized program changes and protect intellectual property.

• Advanced Debugging Tools: Supports real-time monitoring and simulation features within the GX Works software, allowing for faster commissioning and troubleshooting.

• Autonomous Data Logging: The processor can log system data directly to an SD card without requiring an external PC, which is vital for quality tracking and fault analysis.

• Backward Compatibility: Mitsubishi’s design philosophy ensures that logic from older generations can often be migrated to newer processors with minimal modification.

Product Applications

These processors are the core controllers in a wide range of advanced technology sectors:

• Automotive Manufacturing: Coordinating complex robotic welding, painting, and assembly lines where millisecond precision is required.

• Semiconductor Fabrication: Managing ultra-precise chemical delivery systems and cleanroom robotics that require high-speed synchronization.

• Food and Beverage: Controlling high-speed packaging, filling, and labeling machines that manage thousands of units per hour.

• Infrastructure and Energy: Governing large-scale water treatment plants, power distribution grids, and tunnel ventilation systems.

• Motion and CNC Integration: Acting as the master controller for multi-axis synchronized motion in 3D printing, milling, and textile machinery.

Important Precautions

To ensure the longevity and reliable operation of the processor module, users must observe several critical handling guidelines:

• Electrostatic Discharge (ESD): Always wear a grounded wrist strap when handling the processor. Static electricity can damage the internal CMOS circuits without immediate visible failure.

• Battery Management: For CPUs utilizing volatile RAM, the backup battery must be monitored. If the "BAT" LED lights up, replace the battery immediately while the power is on to avoid losing the program.

• Firmware Consistency: When using a multi-CPU system, ensure that all processors have compatible firmware versions to prevent synchronization errors or system crashes.

• Environmental Constraints: Install the module in a cabinet that provides protection from conductive dust and corrosive gases. Overheating can occur if the ventilation slits on the module are obstructed.

• Power-Off Installation: Never insert or remove the processor module from the base unit while the power is applied. This can cause electrical surges that may damage both the CPU and the backplane.
