4NHC-SA06 MITSUBISHI Communication Processor

Product  Description：

Mitsubishi Electric Communication Processors, often referred to as Network or Link Modules within the MELSEC series, are high-performance intelligent modules designed to offload complex data communication tasks from the main PLC CPU. While a standard interface module handles the physical connection, a Communication Processor contains its own dedicated logic to manage high-volume data traffic, protocol conversion, and synchronization across large-scale industrial networks. These units are essential for implementing "e-F@ctory" solutions where seamless data flow between the shop floor and IT systems is required.

Product Parameters

The technical capabilities of these processors are optimized for high-speed, high-capacity data handling:

• Network Compatibility: Specialized for advanced industrial networks such as CC-Link IE TSN, Ethernet/IP, and high-speed computer links.

• Maximum Link Points: Capable of managing thousands of link points per network (e.g., up to 32k bits and 16k words in a single CC-Link IE network).

• Processor Clock Speed: Equipped with an independent high-speed processor to manage data packets without adding scan time to the main PLC CPU.

• Transient Transmission Capacity: High-volume data blocks can be sent in a single transient request, often up to several kilobytes.

• Buffer Memory: Features large-capacity internal buffer memory (often several megabytes) for data caching and asynchronous communication.

• Power Consumption: Typically draws between 0.4A and 0.8A from the base unit’s DC supply depending on the network type.

Product Advantages

Integrating a dedicated Communication Processor into a system provides several strategic benefits:

• System Performance Optimization: By processing communication protocols independently, the main CPU can focus entirely on control logic, ensuring consistent and fast machine cycle times.

• Deterministic Communication: Modules utilizing TSN (Time-Sensitive Networking) technology guarantee that critical control signals arrive at their destination within a fixed timeframe, regardless of other network traffic.

• Simplified Network Configuration: These modules often feature "auto-refresh" settings that automatically synchronize network data with the PLC's internal device memory, reducing the need for complex programming.

• Advanced Troubleshooting Tools: Provides comprehensive diagnostic functions through software, including network loop tests, cable length measurements, and detailed error logs.

• Global Standard Support: Built-in support for multiple international communication standards allows a single Mitsubishi PLC system to easily integrate with equipment from different global vendors.

Product Applications

These processors are the backbone of large-scale automated environments:

• Plant-Wide Networking: Connecting multiple PLC racks across different production lines to create a unified manufacturing execution system (MES).

• High-Speed Synchronized Motion: Managing the extremely tight timing requirements for multi-axis motion control systems in labeling or printing machines.

• IT and Cloud Integration: Facilitating direct communication between the factory floor and enterprise-level servers for real-time production monitoring and analytics.

• Remote I/O Management: Controlling hundreds of remote digital and analog sensors located far from the main control cabinet via fiber optic or shielded cables.

• Redundant System Control: Used in mission-critical applications where a secondary communication processor takes over instantly if the primary network path fails.

Important Precautions

To maintain the high-speed integrity of the communication network, users must observe these guidelines:

• Network Topology Rules: Strictly adhere to the specified network topology (star, line, or ring). Incorrect cabling or exceeding the maximum number of stations can lead to network collisions or total failure.

• IP and Station Addressing: Every module on the network must have a unique station number or IP address. Duplicate addresses are the most common cause of communication timeouts and system instability.

• Shielding and Grounding: Use only specialized high-speed communication cables. The shielding must be correctly terminated to the module's ground terminal to prevent electromagnetic noise from corrupting data packets.

• Transmission Distance: Do not exceed the maximum cable length specified for the transmission speed. For longer distances, use fiber optic repeaters or specialized high-performance switches.

• Parameter Backup: Ensure that network parameters are saved in the non-volatile memory of the module and backed up on an external SD card or PC to ensure quick recovery after a hardware replacement.
