MVL56E-MNETC ControlLogix to Modbus TCP Network Bridge

Product Overview

The ProSoft MVL56E-MNETC (Enhanced Modbus TCP/IP Communication Module) creates a reliable data link between Rockwell Automation ControlLogix systems and Modbus TCP/IP field devices. This module functions as a stand-alone gateway residing in the ControlLogix rack, providing 10/100 Mbps Ethernet connectivity. It effectively eliminates the need for complex ladder logic or third-party drivers by mapping Modbus registers directly into the PLC’s controller tags. We supply this unit as 100% brand new, factory-sealed equipment.

Technical Specifications

Engineering Advantages

Optimized Network Performance

The MVL56E-MNETC utilizes high-performance message processing to handle large volumes of data without stressing the PLC's main CPU. By offloading communication tasks to the specialized ProSoft hardware, the module ensures deterministic performance for critical control loops and high-speed monitoring.

Simplified Configuration Workflow

Engineers utilize the ProSoft Configuration Builder (PCB) to define Modbus commands and address mapping. This tool generates the necessary Add-On Profiles (AOP) and Add-On Instructions (AOI) for Studio 5000, which reduces programming hours and minimizes human error during deployment.

Enhanced Versatility with Dual Modes

The module supports simultaneous Client and Server modes. This allows the ControlLogix PLC to act as a master controlling remote I/O while simultaneously serving data to a SCADA system or HMI acting as a Modbus Client.

Industrial-Grade Durability

Built for harsh factory floors, the MVL56E-MNETC withstands extreme storage temperatures and electrical noise. The hardware maintains stable data throughput in environments where consumer-grade gateways typically fail.

FAQs

Does the MVL56E-MNETC support both Client and Server modes simultaneously?

Yes. The module supports simultaneous multi-client and multi-server operations. It can manage up to 30 concurrent Client connections and handle multiple Server requests from external devices at the same time.

What is the benefit of the 'Enhanced' (E) version over older ProSoft modules?

The 'E' (Enhanced) series provides faster processing power, an updated web server for diagnostics, and improved integration with Studio 5000 via Add-On Profiles. It handles larger data sets more efficiently than legacy MNET modules.

Is any special ladder logic required for installation?

No. While the module requires basic configuration to map data, ProSoft provides Add-On Instructions (AOI) that handle the backplane data transfer automatically. This significantly simplifies the integration process in Logix-based systems.

Can I use this module with CompactLogix systems?

While the MVL56E-MNETC is a physical rack-mounted module for ControlLogix, ProSoft offers functionally equivalent versions for CompactLogix. Ensure your chassis type matches the physical form factor of the module before purchase.
