Q12DCCPU-V 4096 points Mitsubishi Universal model Redundant Power Supply Module
Product Description
The Mitsubishi Q12DCCPU-V is a high-performance C-language controller module belonging to the MELSEC-Q series PLC family. It is designed for advanced automation systems requiring complex data processing and real-time control capabilities. This module uses the VxWorks Version 6.4 real-time operating system (RTOS) and supports programming in C/C++, making it ideal for applications demanding high-speed computation, large-scale data handling, and seamless integration with existing software libraries. It supports up to 4096 I/O points and includes built-in Ethernet and USB ports for enhanced connectivity and communication flexibility.
Key Features
- •
High-Speed Processing: Capable of executing complex calculations and large-volume data processing rapidly, with instruction processing times as fast as 34 nanoseconds for certain operations.
- •
Dual Programming Modes: Offers both a Standard Mode and an Expanded Mode (Mode 12), with the expanded mode providing access to additional memory and network module functionalities, which is useful for debugging and enhanced operations.
- •
C/C++ Programming Support: Allows developers to leverage existing C/C++ codebases, reducing development time and enabling direct hardware access through dedicated function libraries.
- •
Advanced Connectivity: Features multiple programming interfaces, including a 12M USB port and a 115K RS-232 interface (where applicable), facilitating easy connection to programming tools and external systems.
- •
Structured Programming: Supports five programming languages—Ladder Diagram, Statement List, ST (Structured Text), SFC, and FB—alongside structured programming for efficient code organization across up to 252 programs
- •
Large Memory Capacity: Equipped with substantial built-in RAM and supports external memory cards like CF cards for program and data storage expansion.
- •
Robust Diagnostics: Includes constant scan monitoring (configurable from 0.5ms to 2000ms) and fault detection features to ensure system reliability and simplify troubleshooting
Material & Primary Applications
- •
Material: The module is housed in a robust industrial-grade casing designed to withstand harsh environments. It operates reliably within a temperature range of 0 to 55°C and complies with international standards for shock and vibration resistance (JIS B3501, IEC 61131-2).
- •
Primary Applications:
- •
Industrial Automation: Suitable for complex machinery control, high-speed processing lines, and sophisticated robotic systems.
- •
Data-Intensive Systems: Ideal for vision inspection systems and database management applications requiring large memory capacity.
- •
Customized Control Solutions: Its support for a real-time OS and partner OS customization makes it fit for specialized control tasks in sectors like pharmaceuticals, food processing, and automotive manufacturing.
- •
Secure and Standalone Operations: Enhanced security features promote "PC-less" automation, reducing vulnerability and simplifying system architecture.
