PROSOFT MVI56-MNETC
Product introduction
The ProSoft MVI56-MNETC is a high-performance Ethernet/IP-to-Modbus TCP communication module designed for Allen-Bradley ControlLogix PLCs, developed by ProSoft Technology (a Rockwell Automation Encompass Partner). It solves a critical enterprise challenge: enabling seamless, high-speed data exchange between ControlLogix’s Ethernet/IP-based control systems and Modbus TCP-enabled third-party devices—without sacrificing real-time performance or network reliability. Unlike basic Modbus modules that limit throughput or lack redundancy, the ProSoft MVI56-MNETC features gigabit Ethernet (2000 Modbus requests/second) and dual-port DLR/MRP redundancy, making it ideal for large-scale, time-critical applications like automotive assembly, power grid monitoring, and semiconductor manufacturing.
As an “enterprise-grade protocol bridge,” the ProSoft MVI56-MNETC unlocks multi-vendor interoperability while preserving ControlLogix’s native efficiency. For example, a semiconductor plant uses the ProSoft MVI56-MNETC to connect its ControlLogix 1756-L7x PLC (controlling wafer etching tools) to 36 Siemens S7-1500 PLCs (monitoring Modbus TCP-based inspection sensors): the module maps sensor data to Ethernet/IP produced tags, allowing the ControlLogix PLC to adjust etching parameters in <15 ms—critical for maintaining 0.1 μm wafer precision. This integration eliminates $150k in custom driver development and cuts defect rates by 28%.
Whether deployed in distributed manufacturing networks (with hundreds of Modbus TCP devices) or critical infrastructure (needing 99.999% uptime), the ProSoft MVI56-MNETC combines industrial ruggedness with enterprise-grade connectivity. Its dual certifications (ODVA, Modbus Organization) and backplane integration ensure reliable performance, making it indispensable for teams unifying ControlLogix systems with global Modbus TCP ecosystems.
Core advantages and technical highlights
Gigabit Ethernet for High Throughput: The ProSoft MVI56-MNETC’s gigabit Ethernet ports handle up to 2000 Modbus TCP requests/second—double the throughput of entry-level modules—enabling large-scale device polling without bottlenecks. A beverage bottling plant uses the ProSoft MVI56-MNETC to poll 60 Modbus TCP fill-level sensors (every 5 ms) and 24 Rockwell PowerFlex 755 VFDs (via Ethernet/IP): the high throughput ensures the ControlLogix PLC receives real-time data, adjusting fill valves within 10 ms of detecting deviations. This speed reduces product waste by 18% and increases line efficiency by 30% compared to 100 Mbps modules.
Dual-Port Redundancy (DLR/MRP) for Uninterrupted Operation: Unlike single-port modules, the ProSoft MVI56-MNETC supports Ethernet/IP DLR (Device Level Ring) and MRP (Media Redundancy Protocol) via dual gigabit ports—ensuring zero downtime if one network link fails. A power distribution plant uses the module (with DLR) to connect its ControlLogix PLC to 22 Modbus TCP switchgear controllers: during a fiber optic cable fault, the DLR redundancy switches to the backup port in <3 ms, avoiding a 3-hour outage that would have disrupted power to 80,000 households. This redundancy meets the plant’s SIL 2 safety requirements and ISO 55000 asset management standards.
ODVA & Modbus Dual Certification for Interoperability: The ProSoft MVI56-MNETC is certified by both ODVA (Ethernet/IP) and the Modbus Organization—guaranteeing seamless compatibility with all Ethernet/IP and Modbus TCP devices. An automotive assembly plant uses the module to link its ControlLogix PLC to 40 Allen-Bradley PanelView HMIs (Ethernet/IP) and 25 Schneider M340 PLCs (Modbus TCP): the dual certification ensures the HMIs display real-time conveyor status (from Modbus TCP) within 1 ms, avoiding production delays caused by protocol conflicts. This interoperability is critical for multi-vendor networks spanning global supply chains.
ControlLogix Backplane Integration for Low Latency: By plugging directly into the ControlLogix backplane, the ProSoft MVI56-MNETC minimizes data transfer latency to <15 ms—far lower than external gateways (100+ ms). A solar farm uses the module to connect its ControlLogix PLC to 50 Modbus TCP inverters: the low latency ensures inverter output data (kW) reaches the PLC in time to adjust panel orientation for peak sun exposure, increasing energy yield by 9%. Backplane integration also eliminates extra wiring, reducing installation time by 45% compared to external Modbus gateways.
Typical application scenarios
In semiconductor manufacturing, a wafer fabrication plant uses the ProSoft MVI56-MNETC to connect its ControlLogix 1756-L7x PLC (controlling 8 etching tools) to 48 Modbus TCP inspection cameras (via gigabit Ethernet) and 12 Ethernet/IP-enabled vacuum pumps. The module maps camera data (wafer defect coordinates) to ControlLogix tags, allowing the PLC to reject defective wafers before they enter the next process stage. During a scheduled network maintenance, the module’s MRP redundancy switches to the backup port without interrupting data flow—avoiding a 2-hour outage that would have ruined 300 wafers (valued at $120k). The gigabit throughput also supports simultaneous polling of all 48 cameras every 5 ms, maintaining the plant’s 99.99% process yield.
In water treatment, a municipal plant uses the ProSoft MVI56-MNETC to link its ControlLogix PLC to 30 Modbus TCP flow meters (remote pumping stations) and 18 Ethernet/IP chemical dosing pumps. The module acts as a Modbus TCP client to poll flow rates (adjusting doses based on water demand) and as an Ethernet/IP server to share pump status with the plant’s SCADA system. During a cyber security audit, the module’s HTTPS encryption and password protection prevent unauthorized access to Modbus registers—ensuring compliance with EPA Clean Water Act monitoring requirements. The dual-port redundancy also ensures continuous data flow during severe weather events, avoiding $50k in non-compliance fines.

Installation, commissioning and maintenance instructions
Installation preparation: Before installing ProSoft MVI56-MNETC, confirm the Allen-Bradley ControlLogix chassis (1756) has an empty slot and is powered off. Wear ESD wristbands to protect the module and backplane. Align the ProSoft MVI56-MNETC with the chassis guides and firmly seat it into the slot (apply even pressure to avoid bent pins). Power on the ControlLogix PLC and verify the module’s power LED illuminates green (indicates backplane communication). Connect network devices: Use Belden 1694A Cat6a cable to link Port 1 (Ethernet/IP) to ControlLogix-compatible devices (e.g., VFDs, HMIs) and Port 2 (Modbus TCP) to third-party devices. Configure IP addresses via the module’s web interface (default IP: 192.168.1.250) to match the network subnet; enable DLR/MRP in PCB software if redundancy is required.
Maintenance suggestions: Inspect ProSoft MVI56-MNETC monthly: Check LEDs (green = power/backplane, blue = Ethernet link, amber = data transfer, red = fault); Clean Ethernet ports with compressed air (avoid liquids) to remove dust or debris. For troubleshooting, use the web interface to monitor Modbus TCP request logs, Ethernet/IP tag status, and redundancy switch events—if communication fails, verify IP settings, cable continuity (use a Cat6a tester), and device protocol compatibility. Update firmware quarterly via Ethernet (download from ProSoft’s website) to ensure support for new Modbus TCP function codes and Ethernet/IP features. Store spare modules in a dry, 0 °C to +50 °C environment—avoid exposure to extreme temperatures, corrosive gases (e.g., sulfur in wastewater plants), or electromagnetic interference (EMI) from high-voltage equipment.
