PROSOFT MVI56E-MCM

Product Overview

Key Specifications

• Communication Protocols: Modbus RTU/ASCII (Master/Slave), with support for Modbus TCP/IP, EtherNet/IP, DF1, ASCII and DH-485 protocols.
• Port Configuration: Equipped with two independently configurable serial ports (RS-232/RS-422/RS-485), each of which can be set up as a master or slave unit.
• Power Supply: 10–30V DC (24V DC or 5V DC are the most commonly used voltages).
• Operating Temperature: -40°C to +85°C
• Dimensions: Approximately 114mm × 90mm × 30mm

Product Features

• Multi-Protocol Compatibility: Supports a wide range of industrial standard protocols including Modbus RTU/ASCII, TCP/IP and EtherNet/IP, facilitating smooth cross-platform integration.
• Flexible Port Configuration: The two independent serial ports can operate on the same or different Modbus networks, supporting up to 20 master devices and 30 slave devices simultaneously.
• Compact Design: Compliant with DIN rail mounting standards, the module features a space-saving structure ideal for backplane installation scenarios.
• Enhanced Performance: Select models (e.g., MCMXT) offer a conformal coating option, making them suitable for deployment in harsh and extreme industrial environments.

Structure and Components

• Mechanical Structure: Adopts a DIN rail-mountable metal housing, integrated with RJ45 Ethernet ports and standard serial communication interfaces (RS-232/RS-422/RS-485) for reliable connectivity.
• Electronic Components: Internally integrates a Modbus protocol stack, high-performance processor logic and a power management module. It also comes with an LED display module for real-time indication of operating status and error alerts.

Application Areas

• Industrial Automation: Serves as a bridge to connect ControlLogix controllers with other Modbus-enabled devices such as frequency converters and sensors.
• Power Systems: Applied in communication and control systems for power generation, transmission and distribution networks.
• Process Control: Suitable for monitoring and control of industrial processes in chemical, petroleum and pharmaceutical industries.
• SCADA Systems: Functions as a data concentrator to transmit field device data to upper-level host computer systems efficiently.

Installation and Maintenance

• Installation Method: Typically installed in Rockwell Automation ControlLogix backplanes (e.g., 1756 chassis) and secured via DIN rail mounting.
• Power Requirements: The MCMR version requires a power supply of 800 mA @ 5 Vdc provided by the PLC backplane.
• Configuration and Maintenance: Parameter configuration can be completed using ProSoft Configuration Builder (PCB) and Product Discovery Service (PDS). During installation, ensure sufficient backplane power supply; after properly connecting Ethernet and serial interfaces, the PLC can be started to establish communication.

• Back up parameter settings on a regular basis to prevent data loss due to power outages or equipment malfunctions
