FX3S-20MT/DS MITSUBISHI

FX3S-20MT/DS MITSUBISHI communication module

Product  Description：

A Mitsubishi communication module acts as a dedicated interface that allows a PLC to "talk" to other devices. Whether you need to connect to a simple HMI, complex robotic systems, or cloud-based data hubs, these modules handle the protocol translation and physical connection. They support a vast array of protocols including CC-Link IE (Industrial Ethernet), CC-Link, Ethernet/IP, Profibus, Modbus, and Serial (RS-232/485). These units are typically designed for easy mounting on a base unit or integration directly into the PLC rack, featuring high-speed processing to minimize data latency.

Key Product Parameters

While specific parameters vary depending on the model (e.g., RJ71EN71 vs. QJ71C24N), general specifications for these modules include:

• Network Type: Selection includes CC-Link IE Control, CC-Link IE Field, Ethernet, or Serial.

• Transmission Speed: Ranges from 300 bps for older serial connections up to 1 Gbps for high-end CC-Link IE Field modules.

• Maximum Connection Distance: Varies from 15 meters (RS-232) to 100 meters between stations for Ethernet-based cables, extending to kilometers with fiber optics.

• Maximum Number of Nodes: Some modules support up to 120 stations per network segment.

• Data Capacity: Defined by the number of link points (RX/RY) and link registers (RWw/RWr) it can handle per scan.

• Current Consumption: Typically rated in Amperes (A) drawn from the PLC's internal DC power supply.

Product Advantages

Mitsubishi communication modules are highly regarded in the automation industry for several reasons:

• Seamless Integration: Designed specifically for MELSEC hardware, these modules require minimal configuration within the GX Works3 engineering software environment.

• High-Speed Synchronization: CC-Link IE modules offer deterministic communication, ensuring that motion control and safety data arrive at exactly the right millisecond.

• Reduced Wiring Costs: By using network modules, you can replace hundreds of individual wires with a single Ethernet or bus cable, significantly lowering installation time.

• Reliability: Built for harsh industrial environments, they feature high noise immunity and robust hardware construction.

• Scalability: You can easily expand your system by adding more modules or nodes without overhauling your existing control architecture.

Safety and Operational Precautions

To ensure longevity and prevent system failure, users should adhere to the following:

• Power Supply Integrity: Always turn off the external power supply before installing or removing a module to prevent electrical shock or damage to the circuitry.

• Environmental Limits: Use the modules within the specified temperature and humidity ranges; avoid environments with conductive dust, corrosive gas, or high vibration.

• Cable Quality: Use only Mitsubishi-certified cables or those meeting the specific category requirements (e.g., Cat5e SF/UTP for CC-Link IE) to avoid data packet loss.

• Correct Termination: For serial or fieldbus networks like RS-485 or Profibus, ensure that terminating resistors are correctly installed at the physical ends of the line.

• Firmware Compatibility: Ensure the PLC CPU firmware and the engineering software version are compatible with the specific communication module version.

Typical Product Applications

These modules are the backbone of modern "Smart Factories" and find use in:

• Automotive Assembly: Coordinating multi-axis robots and conveyor systems via CC-Link IE Field.

• Water Treatment Facilities: Sending remote I/O data over long distances using fiber optic Ethernet modules.

• Packaging Machinery: Connecting HMIs and frequency inverters (VFDs) using Modbus or Serial protocols for real-time speed adjustment.

• Data Logging: Utilizing Ethernet modules to push production counts and error logs directly to an SQL database or MES system.

• Semiconductor Manufacturing: Precise environmental monitoring and wafer tracking across highly synchronized cleanroom networks.
