Eaton MMINT

MMINT is a Modbus Translator module launched by Eaton, specifically designed to enable protocol conversion between fieldbus (INCOM) and Modbus RTU. It operates on a power supply of 24 VDC–125 VDC (or 120 VAC), supports DIN-rail mounting, and is widely used in industrial automation systems to achieve interconnection and interoperability between different devices.

Key Specifications

• Power Supply Voltage: 120 VAC or 24 VDC–125 VDC
• Operating Temperature: 0 °C ~ 60 °C
• Communication Baud Rate: 1200, 9600, 19200 baud (1 start bit, 8 data bits, no parity, 1 or 2 stop bits)
• Supported Slave Devices: Up to 32 INCOM slaves and 246 Modbus RTU slaves
• Mounting Type: DIN-rail mounting, suitable for enclosed spaces
• Indicators: Status indicator LED, INCOM communication indicator LED, Modbus RS-485 communication indicator LED

Product Features

• Dual Protocol Bridging: Enables bidirectional data conversion between INCOM and Modbus RTU, supporting universal transparent transmission commands.
• Multiple Data Formats: Supports IEEE floating-point and fixed-point data to meet different control requirements.
• High Reliability: Adopts industrial-grade components with anti-interference design, complying with UL 508 standards.
• Easy Maintenance: Modular structure with intuitive LED indicators for communication status, facilitating fault location.
• Safety Protection: Provides complete safety warnings and operating procedures to prevent personal injury from live operations.

Structure and Composition

• Power Supply Module: Converts external 120 VAC or 24–125 VDC to internal operating voltage.
• Communication Interfaces: Includes INCOM (DIN-rail) master interface and Modbus RS-485 slave/master interface.
• Processing Unit: Built-in microprocessor for protocol parsing, data mapping, and forwarding.
• Indicator Panel: Three groups of LEDs for status, INCOM, and Modbus.
• Housing: Metal or high-strength alloy housing, offering dust and moisture protection.

Typical Application Fields

• Power Plant DCS Monitoring Systems: Achieves protocol interoperability between different plant control systems.
• Intelligent Tempered Glass Furnace Systems: Bridges fieldbus and Modbus devices for unified collection of parameters such as temperature and pressure.
• PLC Conveyor Control Systems: Provides transparent communication between PLCs and legacy Modbus devices.
• Fire Water Supply Control Systems: Ensures reliable data transmission for critical safety systems.
• Chemical Liquid Flow Control: Enables multi-protocol integration in industrial control environments requiring high reliability.

Installation and Maintenance Guidelines

• Pre-installation Inspection: Verify the integrity of the DIN-rail, confirm the power supply voltage meets specifications, and ensure the operating environment temperature is within 0 °C–60 °C.
• Safe Operation: Perform wiring and fixing only after power is disconnected; live operations are strictly prohibited to avoid electric shock or equipment damage.
• Wiring Method: According to the wiring diagram provided in the manual, connect INCOM master lines and Modbus RS-485 lines to corresponding ports separately; connect the power supply line to 120 VAC or 24–125 VDC.
• Debugging Steps:Daily Maintenance: Regularly inspect DIN-rail fixing screws, clean dust on the housing, and ensure no abnormal blinking of indicators.
  1. Check if the status LED lights up after power-on.
  2. Use INCOM or Modbus debugging tools to verify normal communication frames.
  3. In case of abnormalities, first check the indicators (INCOM/Modbus) to locate the fault source.
