PROSOFT MVI56E-MNETR

Product introduction

The PROSOFT MVI56E – MNETR is a redundant Modbus TCP communication module developed by ProSoft Technology, specifically engineered for Allen – Bradley’s ControlLogix 1756 chassis—including redundant chassis configurations. As the upgraded redundant version of the PROSOFT MVI56E – MNET, it addresses the critical need for uninterrupted communication in mission – critical industrial systems (such as nuclear power, chemical processing, and oil refineries) where even seconds of downtime can cause $100k + losses or safety violations.

By integrating dual Ethernet ports for network redundancy (DLR/MRP) and real – time backplane sync for module redundancy, the PROSOFT MVI56E – MNETR ensures 99.999% uptime—far exceeding the standard PROSOFT MVI56E – MNET’s single – network design. It retains all core features of the PROSOFT MVI56E – MNET (e.g., Modbus TCP client/server mode, 8192 data registers) while adding failover mechanisms that switch between redundant paths in < 5 ms. For facilities upgrading from the PROSOFT MVI56E – MNET to meet safety or reliability standards (e.g., NERC CIP, IEC 61508), the PROSOFT MVI56E – MNETR offers drop – in compatibility, minimizing hardware replacement costs and production disruption.

Core advantages and technical highlights

Dual – Layer Redundancy (Network + Module): The PROSOFT MVI56E – MNETR delivers two levels of redundancy to eliminate single points of failure. Its dual Ethernet ports support DLR/MRP protocols—automatically switching to the backup port if the primary network link fails (e.g., cable damage, switch outage) in < 5 ms. When paired with a ControlLogix redundant chassis, the module mirrors configuration and data between primary and secondary units in real time—ensuring no data loss if the primary module malfunctions. A chemical plant uses this feature to connect a ControlLogix PAC to 18 Modbus TCP reactor pressure sensors: during a fiber optic network cut, the PROSOFT MVI56E – MNETR switches to a cellular backup, avoiding a 2 – hour shutdown that would have ruined $500k of batch production.

Seamless Compatibility with PROSOFT MVI56E – MNET Setups: The PROSOFT MVI56E – MNETR is fully compatible with existing PROSOFT MVI56E – MNET configurations—using the same Studio 5000 AOP and PCB software (v6.5 +) with an added redundancy wizard. This means customers upgrading from the PROSOFT MVI56E – MNET can reuse existing Modbus register maps, PLC logic, and training resources. A power plant upgrading 12 modules completes configuration in 3 hours (vs. 8 hours with third – party redundant systems) by importing PROSOFT MVI56E – MNET settings and enabling redundancy via the PCB wizard—minimizing downtime for critical energy production processes.

Functional Safety Compliance (IEC 61508 SIL 2): Unlike the standard PROSOFT MVI56E – MNET, the PROSOFT MVI56E – MNETR meets IEC 61508 SIL 2 requirements for functional safety—critical for applications where communication failures could lead to safety hazards. It includes built – in self – tests (BIST) that run every 100 ms to verify hardware integrity, plus redundant data paths to prevent single – point errors. A nuclear power plant uses this compliance to connect Modbus TCP radiation sensors to a ControlLogix PAC, ensuring the system meets NRC safety standards and avoids regulatory penalties.

Typical application scenarios

In oil refineries, a refinery deploys the PROSOFT MVI56E – MNETR with redundant ControlLogix PACs to monitor 48 Modbus TCP crude oil pipeline pressure sensors and control 24 Modbus TCP valves. The module’s dual Ethernet ports connect to separate fiber optic networks (primary) and wireless backup (secondary). During a storm that damages the primary fiber, the PROSOFT MVI56E – MNETR fails over in 3 ms—allowing the PAC to detect a pressure drop (indicating a leak) and close valves within 150 ms. This prevents a spill that would have incurred $1M + in cleanup costs and EPA fines, while the module’s SIL 2 compliance meets OSHA process safety standards.

In pharmaceutical manufacturing, a drugmaker uses the PROSOFT MVI56E – MNETR to connect a ControlLogix PAC to 12 Modbus TCP bioreactor temperature sensors and 8 Modbus TCP dosing pumps. The module’s redundancy ensures no communication loss during batch production—critical for FDA – regulated processes where interruptions can ruin $250k batches of life – saving drugs. The PROSOFT MVI56E – MNETR also shares real – time batch data with a Modbus TCP SCADA system via redundant paths, simplifying compliance with FDA 21 CFR Part 11 by ensuring data integrity and auditability.

In municipal water treatment, a utility uses the PROSOFT MVI56E – MNETR to connect a ControlLogix PAC to 16 Modbus TCP water flow meters and 10 Modbus TCP pump VFDs. The module’s dual networks (Ethernet + cellular) ensure continuous communication during extreme weather (e.g., hurricanes that knock out wired networks). During a storm, the PROSOFT MVI56E – MNETR switches to cellular, allowing the PAC to maintain pump operation and avoid flooding in residential areas—protecting the utility from $500k + in property damage claims.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the PROSOFT MVI56E – MNETR, power off the ControlLogix 1756 chassis (redundant or standard) to prevent backplane damage. Wear an ESD wristband to protect the module’s electronics. For redundant setups, ensure the chassis has two empty slots (for primary/secondary modules) and verify compatibility with 1756 – Redundant Chassis firmware v30 +. Gather tools: flat – head screwdriver (chassis locking screws), two Cat6a Ethernet cables (for dual networks), and a laptop with PCB v6.5 +. Avoid installing the PROSOFT MVI56E – MNETR near heat sources (e.g., power supplies) or in dusty areas—use a NEMA 4 enclosure for outdoor or harsh environments.

Maintenance suggestions: Conduct monthly checks of the PROSOFT MVI56E – MNETR: verify green “Power” LEDs, steady blue “Redundancy Sync” LEDs, and blinking yellow “Data Activity” LEDs on both primary and secondary modules. Use the web interface to review failover logs and confirm sync status. Every 3 months, test failover by disconnecting the primary Ethernet cable—ensure the module switches to the secondary port in < 5 ms (confirmed via PCB’s “Redundancy Diagnostic” tab). For troubleshooting, if sync fails, check that primary/secondary modules have identical firmware versions and configuration settings. Update the PROSOFT MVI56E – MNETR’s firmware quarterly via PCB (takes < 5 minutes per module) to access redundancy performance improvements. Store spare modules in a dry environment (- 20 °C to + 50 °C) with pre – loaded configurations for quick replacement.
