MR-J4-500B4-RJ163 MITSUBISHI Processor module

Product  Description：

Mitsubishi Electric Processor Modules, commonly known as CPUs within the MELSEC Programmable Logic Controller (PLC) series, act as the primary intelligence of an automation system. These modules execute the user-stored control program, manage system memory, and coordinate data exchange across the entire PLC rack and network. From the compact FX series to the high-performance iQ-R series, these processors are designed to handle everything from simple machine timing to complex, multi-axis motion synchronization.

Product Parameters

The performance of a Mitsubishi Processor Module is defined by its computational throughput and memory capacity:

• Execution Speed: Basic instruction processing speeds are incredibly fast, typically ranging from 0.9 nanoseconds to 34 nanoseconds depending on the model.

• Program Capacity: Storage for user logic ranges from 10k steps for entry-level units to 1200k steps or more for high-end industrial processors.

• Device Points: Capable of managing thousands of internal relays, timers, and data registers (e.g., up to 65,536 points in advanced models).

• Multi-CPU Capability: High-end backplanes support the installation of up to four CPUs simultaneously, allowing for the segregation of sequence control, motion control, and CNC tasks.

• Communication Interfaces: Modern units feature built-in Ethernet (100Mbps/1Gbps), USB for programming, and SD card slots for data logging and program backup.

• Internal Memory: Utilizes high-reliability Flash and SRAM to ensure program integrity even during power fluctuations.

Product Advantages

Mitsubishi Processor Modules are globally recognized for their "Never-Stop" philosophy and engineering precision:

• High-Speed Bus Integration: The iQ-R series features a high-speed system bus that dramatically reduces communication lag between the processor and specialized modules.

• Built-in Security: Includes hardware-based security keys and IP address filters to prevent unauthorized access, tampering, or intellectual property theft of the control logic.

• Advanced Debugging: Supports real-time simulation and "Online Change" capabilities, allowing engineers to modify the program without stopping the production line.

• Data Integrity: Features ECC (Error Correction Code) memory to detect and correct single-bit errors, ensuring the system does not crash due to memory corruption.

• Platform Scalability: The modular nature allows users to upgrade the processor to a more powerful version without needing to rewire the entire I/O system.

Product Applications

The processor module is the heart of various sophisticated industrial operations:

• Automotive Production: Coordinating robotic welding, painting, and assembly lines where sub-millisecond precision is required.

• Semiconductor Fabrication: Managing high-speed wafer handling and precision environmental control in cleanrooms.

• Energy Management: Controlling complex power distribution grids and renewable energy conversion systems.

• Food and Beverage: Governing high-speed bottling and packaging lines that require complex synchronization of sensors and actuators.

• Motion Control: Driving multiple servo axes for CNC machining, 3D printing, or high-speed labeling machines.

Important Precautions

To ensure the longevity and stable operation of the processor, the following precautions should be followed:

• Battery Replacement: If using volatile memory (SRAM), monitor the "BAT" LED indicator. Replace the lithium battery within the specified timeframe to avoid losing the user program during power outages.

• Electrostatic Discharge (ESD): Always touch a grounded metal object before handling the processor. Static electricity can permanently damage the internal CMOS logic.

• Power Supply Matching: Only use the processor with a compatible Mitsubishi Power Supply module. Using a third-party or incorrectly rated power source can lead to erratic behavior or hardware failure.

• Firmware Updates: Ensure that the CPU firmware is compatible with the version of the engineering software (GX Works) being used. Mismatched versions may result in compilation errors.

• Thermal Environment: Ensure the PLC cabinet has adequate ventilation. The processor generates heat during high-speed calculations; if the ambient temperature exceeds 55°C, the lifespan of the electrolytic capacitors will be significantly reduced.
