Mitsubishi's PLC network builds upon the traditional MELSEC network, enhancing it in terms of performance, functionality, and user experience. The Q series PLC offers a clear three-layer network structure, providing the most suitable network solutions for different applications.
(1) **Information Layer / Ethernet**
The information layer is the top level of the network system, primarily used for transmitting data such as production management, quality control, and equipment operation between PCs and PLCs. This layer uses standard Ethernet, allowing connections with Windows PCs, UNIX workstations, and various FA devices. The Ethernet module in the Q series PLC now supports Internet email transmission, enabling users to send and receive production-related emails globally for remote monitoring and management. Additionally, the built-in FTP server and MELSEC-specific protocols make program uploads/downloads and information exchange straightforward and efficient.
(2) **Control Layer / MELSECNET/10 (H)**
MELSECNET/10 is the middle layer of the network system, designed for fast and reliable data exchange between PLCs and CNCs. It has gained widespread recognition due to its real-time performance, ease of setup, and support for non-programmed data sharing. With a high number of connected devices, it’s one of the most popular control networks in Japan. MELSECNET/H, an upgraded version, enhances real-time communication and increases data capacity, making it more adaptable to modern industrial demands. However, it is currently only available for the Q series PLCs.
(3) **Device Layer / Fieldbus CC-Link**
CC-Link is the lowest layer of the network, connecting PLCs with sensors, drives, and other field devices. By using CC-Link, the number of cables is significantly reduced, improving system maintainability. It supports not just simple on/off signals but also intelligent systems like ID readers, barcode scanners, inverters, and HMI panels. This allows for full data communication and terminal production information management. With centralized machine status monitoring, maintenance efficiency is greatly improved. In the Q series, CC-Link offers enhanced features and easier operation.
When communicating within Mitsubishi's PLC network, users don’t feel any differences or disruptions between network types. Data communication, remote monitoring, modification, and debugging can be done seamlessly across different layers. MELSECNET/H and CC-Link use cyclic communication, automatically sending and receiving data without requiring special programming—only simple parameter settings are needed. They also use a broadcast method for communication, enabling efficient data sharing.
For the Ethernet, MELSECNET/H, and CC-Link networks used in the Q series PLCs, network parameters and functions can be easily set through the GX Developer software, making configuration straightforward. In addition to these, the Q series supports other manufacturer networks like Profibus, Modbus, DeviceNet, ASi, and more. It also enables serial communications via RS-232, RS-422, RS-485, and data transmission over data lines and telephone lines, offering a wide range of connectivity options.
