GT15-J71LP23-25 MITSUBISHI Communication Processor

Product  Description：

Mitsubishi Electric Communication Processors, often referred to as Network or Information Modules within the MELSEC series, are high-performance specialized units designed to offload complex data processing and communication tasks from the main PLC CPU. Unlike basic interfaces, these processors have their own dedicated computing resources to manage high-volume data traffic, file transfers, and sophisticated protocol conversions, ensuring that the control logic execution remains fast and deterministic.

Product Parameters

The technical capabilities of a Mitsubishi Communication Processor are defined by its data throughput and multi-tasking capacity:

• Processor Type: High-speed RISC or dedicated communication SoC (System on Chip) that operates independently of the PLC scan cycle.

• Buffer Memory: Large-capacity internal memory, often 512KB to several megabytes, used for storing large data packets or SQL database queries.

• Network Throughput: Supports high-speed transmission up to 1 Gbps on CC-Link IE TSN or standard 10/100/1000 Mbps Ethernet.

• Simultaneous Connections: Capability to maintain dozens of active TCP/IP or UDP/IP sessions without degrading the performance of the main CPU.

• Protocols Supported: FTP (Client/Server), HTTP (Web Server), SMTP (Email), SNMP (Network Management), and specialized database connectivity like SQL Server or Oracle.

• Storage Expansion: Integrated SD/SDHC card slots for local data logging, recipe storage, and firmware management.

Product Advantages

Mitsubishi Communication Processors provide a strategic advantage in complex, data-driven manufacturing environments:

• CPU Load Reduction: By handling all "heavy lifting" associated with IT-level communications, these processors prevent the main PLC CPU from experiencing scan-time fluctuations or "jitter."

• Seamless IT and OT Convergence: These units act as a direct bridge to the information technology (IT) layer, allowing for direct database insertion without the need for a separate gateway PC.

• Real-Time Web Monitoring: Built-in web server functions allow engineers to access machine status, error logs, and performance metrics via a standard browser on a tablet or smartphone.

• High Reliability: Designed with industrial-grade components that lack the cooling fans or moving parts found in traditional industrial PCs, significantly increasing the Mean Time Between Failures (MTBF).

• Advanced Synchronicity: Supports Time-Sensitive Networking (TSN), allowing for the synchronization of multiple networks while maintaining strict priority for control data over general information data.

Product Applications

These processors are essential for facilities moving toward Industry 4.0 standards:

• Database Integration: Automatically uploading production data, quality inspection results, and traceability information directly to a central SQL database.

• Remote Monitoring and Alarming: Sending automatic email notifications with attached log files to maintenance teams whenever a specific machine fault occurs.

• File Transfer and Management: Using FTP to download new production recipes or upload daily performance reports to a remote server.

• Large-Scale Network Management: Coordinating data exchange between hundreds of remote I/O stations and multiple PLC racks in a wide-area network.

• Visualization Hubs: Providing the data source for enterprise-wide dashboards and SCADA systems that require high-resolution, real-time updates from the factory floor.

Important Precautions

To ensure the security and stability of the communication processor, users must observe several critical factors:

• Network Security: Since these modules connect directly to IT networks, it is vital to utilize the built-in security features, such as IP address filters and password protection, to prevent unauthorized access.

• Memory Management: When performing frequent data logging to an SD card, monitor the card's life cycle and use industrial-grade SLC cards to prevent data corruption from high-frequency write cycles.

• Power Consumption: Communication processors can draw significant current from the base unit backplane. Verify that the power supply module has sufficient capacity to support the processor along with all other installed modules.

• Firmware Synchronization: Ensure that the communication processor's firmware is compatible with the version of the PLC CPU and the engineering software (GX Works3) being used.

• Bandwidth Allocation: Carefully configure the communication cycle settings. Setting a cycle that is too short for the amount of data being transferred can lead to "communication timeout" errors or network congestion.
