Modbus TCP/IP Multi Client

Enhanced Communications

Module for Remote Chassis

MVI56E-MNETCR

The MVI56E Modbus TCP/IP Multi Client Enhanced Communication Module for Remote

Chassis allows Rockwell Automation ControlLogix Programmable Automation Controllers

(PACs) to easily interface 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, and has a web server to access on-board documentation, Add-On Instructions, and

sample program files.

The MVI56E-MNETCR utilizes a reduced Input/Output (I/O) data block for transferring data

to and from a ControlLogix processor. This reduced data block makes it ideal for use in

remote rack applications over ControlNetTM. For EtherNet/IPTM applications where

bandwidth is not an issue, it is strongly recommended to use the MVI56E-MNETC.

Features

Benefits

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.



Programmatically 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, saving you money



Allows support of IT and Automation network segmentation

MVI56 backward compatible



Assists in extending current MVI56 applications by using newer technology that supports

existing MVI56 ladder logic and module configuration

Configuration

ProSoft Configuration Builder (PCB) provides a graphical configuration tool for quick and easy management of module configuration

files, as well as viewing module diagnostic information.

Route connections over multiple EtherNet/IP or ControlNet paths with CIPconnect technology, allowing you to manage the module

from remote locations.

The MVI56E-MNETCR Setup Guide, with the sample configuration, provides step-by-step instructions on how to move data through

the module from the Modbus TCP/IP network to the processor.
