AJ65SBTB1-32DT1 MITSUBISHI Communication Processor

Product  Description：

The Mitsubishi Communication Processor is a specialized hardware module that expands the connectivity of a PLC system. It allows the PLC to exchange data with other controllers, computers, human-machine interfaces (HMIs), and field devices using various protocols. These modules handle the complex task of protocol translation and data framing, offloading these duties from the main CPU to ensure high-speed system performance.

Product Parameters

The technical specifications vary depending on the specific model, such as the QJ71C24N for serial or QJ71E71-100 for Ethernet. Common parameters include:

• Communication Interfaces: Support for Ethernet (10BASE-T/100BASE-TX), RS-232, RS-422, and RS-485.

• Transmission Speeds: Serial baud rates typically range from 300 bps up to 230.4 kbps, while Ethernet modules support 10/100 Mbps or 1 Gbps.

• Maximum Transmission Distance: Ethernet supports up to 100 meters per segment, while RS-422/485 can reach up to 1200 meters.

• Protocol Support: Compatible with MC Protocol (Melsec Communication), Modbus/TCP, Modbus/RTU, CC-Link IE, and Profibus.

• Data Capacity: Capable of high-capacity batch transfers, often supporting hundreds of words per communication cycle.

• Power Consumption: Typically low voltage DC, such as 5V DC or 24V DC, drawn from the PLC backplane or an external supply.

Product Advantages

Mitsubishi communication processors are highly regarded in industrial automation for several reasons:

• Seamless Integration: Designed to work natively within the MELSEC ecosystem, allowing for "program-less" communication setup in many cases.

• High Reliability: Built for harsh industrial environments with high resistance to noise and temperature fluctuations.

• Flexibility: Users can choose between predefined protocol libraries for standard devices or create non-procedure protocols for custom hardware like barcode scanners.

• Advanced Security: Many models include remote password functions and IP filtering to prevent unauthorized access to the control network.

• Diagnostic Tools: Real-time monitoring and diagnostic functions allow engineers to troubleshoot connection issues directly through GX Works software.

Safety and Operational Precautions

To ensure system stability and longevity, the following precautions should be observed:

• Power Down for Installation: Always shut off the external power supply for all phases before mounting or removing the module to prevent electrical shock or damage.

• Wiring Separation: Do not bundle communication cables with high-voltage main circuit lines or power cables. Maintain a minimum distance of 100mm to avoid signal interference and noise.

• Static Electricity: Before handling the module, touch a grounded metal object to discharge static electricity from your body, as electronic components are sensitive to ESD.

• Tightening Torque: Ensure terminal screws are tightened within the specified torque range. Under-tightening causes short circuits, while over-tightening can damage the module casing or screws.

• Environment: Operate only within the specified temperature and humidity ranges. Ensure the control panel is free of conductive dust and oil mist.

Product Applications

Mitsubishi Communication Processors are utilized across diverse industries for complex data exchange tasks:

• Factory Automation: Connecting multiple PLCs across a production line to synchronize conveyor speeds and assembly robots.

• SCADA Systems: Enabling top-level supervisory computers to monitor real-time production data and send control commands to the factory floor.

• Warehouse Management: Interfacing with barcode readers, RFID scanners, and automated guided vehicles (AGVs) using serial or Ethernet links.

• Remote Monitoring: Using modems or VPN gateways to monitor equipment status in distant locations, such as water treatment plants or pump stations.

• Third-Party Integration: Allowing Mitsubishi PLCs to communicate with non-Mitsubishi devices like variable frequency drives (VFDs) or temperature controllers via Modbus.
