ProSoft MVI56-MBP Modbus Master/Slave Communication Module for ControlLogix
Product Overview:ProSoft MVI56-MBP
The ProSoft MVI56-MBP is a high-performance Modbus Master/Slave Communication Module designed to enable seamless integration between Rockwell Automation’s ControlLogix platform and Modbus RTU/ASCII devices, making it a critical component in industrial automation ecosystems. As part of ProSoft’s MVI56 Series of communication gateways, this module bridges the gap between legacy Modbus equipment (e.g., sensors, drives, and PLCs) and modern Ethernet-based control systems, facilitating real-time data exchange and centralized monitoring. The MVI56-MBP supports both master and slave operations, allowing it to initiate communication with up to 31 Modbus slaves or respond to requests from a Modbus master, ensuring flexibility in diverse industrial setups.
Engineered for reliability, the ProSoft MVI56-MBP features a rugged design that complies with industrial standards for shock, vibration, and temperature tolerance. Its plug-and-play compatibility with ControlLogix 1756 I/O racks eliminates the need for custom programming, reducing integration time and minimizing errors. The module’s advanced diagnostics, accessible via Rockwell’s Studio 5000 software, provide real-time insights into communication health, packet statistics, and device status, enabling proactive maintenance and reducing downtime. Whether deployed in manufacturing plants, energy facilities, or water treatment systems, the MVI56-MBP enhances operational efficiency by enabling seamless interoperability between disparate systems.
In automation architectures, the ProSoft MVI56-MBP serves as a vital communication hub, translating ControlLogix tag data into Modbus registers and vice versa. Its dual-channel capability (RS-232/485) supports simultaneous communication on two independent networks, expanding system scalability. By consolidating Modbus devices into the ControlLogix ecosystem, this module streamlines data management, improves process visibility, and supports compliance with industry standards for remote monitoring and control.

Key Features and Advantages:ProSoft MVI56-MBP
Dual-Mode Communication: The MVI56-MBP operates as both a Modbus master and slave, offering flexibility to either poll field devices for data or act as a slave responding to commands from a higher-level system. This dual functionality makes it suitable for the most complex industrial networks.
Seamless ControlLogix Integration: Designed specifically for Rockwell’s ControlLogix platform, the module integrates natively with Studio 5000, allowing users to configure communication parameters, map tags, and monitor diagnostics through a familiar interface. No additional software licenses are required, reducing total cost of ownership.
Rugged Industrial Design: Built to withstand harsh environments, the MVI56-MBP features a metal enclosure, conformal coating, and wide temperature range, ensuring reliable operation in factories, oil refineries, and outdoor installations. Its compliance with Class I Div 2 standards further extends its usability in hazardous areas.
Advanced Diagnostics: Real-time LED indicators and detailed fault logging provide instant feedback on communication status, baud rate, and error conditions. The module’s built-in web server (accessible via Ethernet) allows remote monitoring and configuration, enhancing troubleshooting efficiency.
Scalable Architecture: With support for up to 31 Modbus devices per channel and dual independent serial ports, the MVI56-MBP can handle large-scale deployments without compromising performance. Its modular design also allows easy expansion in ControlLogix racks alongside other I/O modules.
Protocol Flexibility: In addition to Modbus RTU and ASCII, the module supports custom protocols via ProSoft’s MVI56-EIP (EtherNet/IP) companion modules, enabling hybrid network setups and future-proofing against technological upgrades.
