Mitsubishi Q06UDVCPU

The Mitsubishi Q06UDVCPU is an ultra-high-speed Universal Model QCPU from the MELSEC-Q series. The “V” in the model name identifies it as the “High-speed Universal” variant, which significantly outperforms the older “UDEH” models in terms of processing speed, data handling, and built-in features.

It is designed for complex, high-precision applications such as multi-axis motion control, high-speed packaging, and large-scale data logging.

1. Processing Power and Speed

The Q06UDVCPU is one of the fastest CPUs in the MELSEC-Q lineup, offering micro-second level precision.

• Basic Instruction Speed (LD): 1.9 ns (nanoseconds). For context, this is nearly 5 times faster than the standard Universal QCPUs.

• Floating Point Addition: 0.014 µs, making it ideal for complex mathematical calculations and PID loops.

• Program Capacity: 60K steps ($240$ KB).

• I/O Capacity: Supports up to 4,096 local points and 8,192 total points (with remote I/O).

2. Built-in Connectivity

This CPU eliminates the need for separate communication modules for most standard tasks:

• Built-in Ethernet: 100/10 Mbps port (RJ45). Supports MC Protocol, FTP server/client, and high-speed communication with HMIs (like the GOT2000 series).

• Built-in USB: Mini-B port for high-speed programming and monitoring via GX Works2 or GX Works3.

• SD Memory Card Slot: Supports SD and SDHC cards (up to 32 GB). This is used for:

  • Storing large data logs.

  • Automatic backup/restore of programs.

  • Booting the PLC from the memory card.

4. Specialized Features

• Data Logging Function: One of the hallmark features of the “V” series. It can log data directly to the SD card at high speeds without requiring a dedicated logging module.

• Multi-CPU High Speed: Features a dedicated bus for synchronized control between multiple CPUs (e.g., a PLC CPU and a Motion CPU), achieving an operation cycle of 0.88 ms.

• Intellectual Property Protection: Supports 32-character passwords and the ability to prevent unauthorized device connections.

• SRAM Cassette Slot: Allows you to expand the internal “Standard RAM” up to 8 MB using a Q4MCA-MBS cassette for large-scale data processing or recipes.

5. Physical Dimensions

• Width: 27.4 mm

• Height: 98 mm

• Depth: 115 mm

Maintenance & Programming Tips

• Hardware Migration: If you are upgrading from a Q06UDEHCPU, the Q06UDVCPU is a physical drop-in replacement on the same base unit, but you must update the “PLC Type” in your GX Works project before downloading.

• Battery Maintenance: If the “BAT” LED on the front of the CPU turns red, you have approximately 1 month to replace the Q6BAT battery before the program in the standard RAM is lost.

• Firmware: Ensure you are using the latest version of GX Works3 to take full advantage of the “V” series high-speed logging and SD card features.
