GT16-70PSGB MITSUBISHI

GT16-70PSGB MITSUBISHI central processing unit

Product  Description：

Mitsubishi Electric CPUs are the core processing engines for the MELSEC series Programmable Logic Controllers (PLCs). As the "brain" of the automation system, the CPU module executes the control program, manages system memory, and coordinates high-speed communication between I/O modules, motion controllers, and network interfaces. Mitsubishi offers a wide range of CPUs—from the compact iQ-F series to the high-performance iQ-R series—designed to meet the demands of Industry 4.0 and advanced manufacturing.

Product Parameters

While specific technical values depend on the series (iQ-R, Q, L, or iQ-F), general performance parameters include:

• Instruction Execution Speed: Ultra-high-speed processing, with basic instructions (LD) executed in as little as 0.9 nanoseconds to 1.9 nanoseconds.

• Program Capacity: Highly scalable memory options ranging from 10k steps for small machines to 1200k steps (or more) for large-scale plant control.

• Multi-CPU Coordination: Capability to host up to 4 CPUs on a single base unit, allowing for distributed processing of sequence logic, motion, and safety functions.

• Built-in Interfaces: Standard integrated ports typically include Ethernet (100BASE-TX/10BASE-T), USB (mini-B) for programming, and SD/SDHC memory card slots for data logging.

• Floating Point Accuracy: Advanced math processing for complex equations, with double-precision floating-point instructions to minimize calculation errors.

• Scan Time Management: Fixed scan interrupt programs can be set as low as 100 microseconds to ensure high-accuracy response for high-speed I/O.

Product Advantages

Mitsubishi CPUs are global leaders in industrial control due to their balance of speed, stability, and intelligence:

• High-Speed System Bus: Newer generations (like the iQ-R) feature a system bus up to 40 times faster than previous models, drastically reducing communication bottlenecks.

• Integrated Safety and Security: Built-in hardware security keys prevent unauthorized program uploads, while integrated safety CPUs allow standard and safety control on the same rack.

• Intelligent Diagnostics: Features like the "Event History" function automatically record system errors and program changes, simplifying root-cause analysis during downtime.

• Predictive Maintenance: Embedded AI and data logging capabilities allow the CPU to analyze machine health and predict potential failures before they occur.

• Flexible Programming: Full support for international standards (IEC 61131-3), allowing developers to use Ladder, Structured Text, Function Blocks, and SFC simultaneously.

Product Applications

The versatility of these CPUs makes them suitable for nearly every automated sector:

• Automotive Manufacturing: Synchronizing high-speed robotic welding cells and complex assembly lines with microsecond precision.

• Semiconductor Processing: Controlling high-accuracy wafer handling and vacuum environments where timing and vibration control are critical.

• Process Control: Managing large-scale PID loops and analog data for chemical plants, water treatment, and food processing.

• Motion and Positioning: Driving multi-axis servo systems for high-speed packaging, printing, and CNC machining operations.

• Energy Management: Acts as an edge controller for monitoring power consumption and optimizing utility usage in "Smart Factories."

Important Precautions

To maintain the performance and safety of the CPU module, the following guidelines are mandatory:

• Electrostatic Discharge (ESD): Always discharge static electricity from your body by touching a grounded metal object before handling the CPU or its memory cards.

• Wiring Separation: Maintain a minimum distance of 100mm between control/communication cables and high-voltage power lines to prevent electromagnetic interference (EMI).

• Power Sequencing: Ensure the external power supply is turned off in all phases before mounting or removing the CPU module from the base unit.

• Battery Handling: For modules using a backup battery, do not charge, disassemble, or heat the battery. Replace it only with the specified Mitsubishi model to prevent data loss.

• Environment and Mounting: Install the CPU in a clean, dry control panel that meets the specified vibration and temperature ratings (typically 0°C to 55°C or 60°C).

• Memory Protection: Do not remove the SD card or turn off the power while the "SD Card Access" LED is flashing, as this can result in corrupted system data or program loss.
