Modbus TCP/IP Multi Client Enhanced Network Interface Module with Reduced Data Block for ControlLogix


Which of our Modbus TCP/IP modules is best for your application?

Watch this Video


The MVI56E Modbus TCP/IP Multi Client Enhanced Communication Module for Remote Chassis allows Rockwell Automation ControlLogix Programmable Automation Controllers (PACs) to interface easily with multiple Modbus TCP/IP server-compatible instruments and devices. The Multi Client module improves performance when controlling multiple servers on a Modbus TCP/IP network, by supporting up to 30 clients.
MVI56E enhancements include configuration and management through the module Ethernet port, CIPconnect technology for bridging through ControlNet and EtherNet/IP networks, and has a web server to access on-board documentation, Add-On Instructions, and sample program files.
This module uses a small I/O data image for transfer of data between the module and the ControlLogix processor, making it ideal for ControlNet or Ethernet applications with the module in a remote rack.

Características y Beneficios

Supports up to 30 Clients

  • Faster response for multi server applications
  • Reduces network traffic
  • Minimizes impact to other server communications when one server device goes off-line

RSLogix 5000 Integrated

  • The module communication is integrated with RSLogix 5000 using a supplied Add-On Instruction (AOI) or ladder file
  • No additional PAC/PLC programming required

Enable/Disable commands easily from ladder logic.

  • Programatically enable various networked devices and their functions to support multiple applications or recipes, without having to reconfigure the module

Remotely configure and diagnose problems

  • Easy to use Windows-based configuration software connects through remote racks using EtherNet/IP and/or ControlNet via a 1756-EnxT and/or 1756-CNB interface module without requiring RSLinx OEM saving you money
  • Allows support of IT and Automation network segmentation

Web-enabled Ethernet port

  • The module has a built-in web server for easy access to documentation, module status, and to update firmware

MVI56 backward compatible

  • Assists in extending current MVI56 applications by using newer technology that supports existing MVI56 ladder logic and module configuration


  • Backward compatible with previous MVI56-MNETCR versions
  • Single-slot 1756 ControlLogix backplane compatible
  • 10/100 Mbps auto crossover detection Ethernet configuration and application port
