Description

Mitsubishi Q02CPU CPU Module

Product Dimensions：

The Mitsubishi Q02CPU is a high-performance, basic-model CPU module belonging to the MELSEC-Q Series Programmable Logic Controller (PLC) family. Known for its reliability and modularity, it is designed for small to medium-scale automation tasks.

Here is a detailed breakdown of the product in English.

1. Product Overview

The Q02CPU is part of the “Q Mode” lineup, offering a significant leap in processing speed and memory capacity compared to the older A-Series or FX-Series. It serves as the “brain” of the PLC system, coordinating inputs, outputs, and complex logic through various expansion modules (I/O, Analog, Positioning, etc.).

3. Key Advantages

• High-Speed Processing: With a base instruction speed of 0.079 microseconds, it handles logic execution rapidly, reducing scan times for sensitive processes.

• Compact Design: The slim profile saves significant space in electrical cabinets.

• Scalability: It allows users to start small and expand by adding specialized modules (Ethernet, Motion Control, Temperature Control) without replacing the CPU.

• Reliability: Built for industrial environments with high resistance to noise, vibration, and temperature fluctuations.

• Advanced Programming: Supports multiple languages including Ladder Diagram (LD), Structured Text (ST), and Sequential Function Chart (SFC) via GX Works2 or GX Developer.

4. Important Considerations (Precautions)

• Battery Maintenance: The CPU uses a buffer battery (typically Q6BAT) to retain data in the SRAM. You must monitor the “BAT” LED and replace the battery while the power is ON to avoid data loss.

• Communication Port: Unlike newer models (like the Q03UDE), the Q02CPU relies on RS-232. You may need a USB-to-RS232 adapter or a specialized SC-09 cable to connect to modern laptops.

• Memory Limitations: While 28k steps is sufficient for many tasks, complex data logging or extensive HMI screens might require an additional Memory Card (SRAM or Flash).

• Firmware Compatibility: Ensure your programming software (GX Works2) is updated to support the specific hardware revision.

5. Typical Applications

The Q02CPU is widely used in industries requiring precise logic control and moderate data handling:

• Automotive Assembly: Controlling conveyors and robotic interlocking.

• Packaging Machinery: Managing high-speed filling, sealing, and labeling.

• Water Treatment: Monitoring sensors and controlling pumps/valves over a wide area.

• Semiconductor Manufacturing: Precise environmental control and wafer handling logic.

• Building Automation: Managing HVAC systems and lighting for large facilities.
