MVI56 Modbus主从通信模块

减少数据块允许ControlLogix处理器接口

很容易与其他Modbus协议兼容的设备。

兼容的设备不仅包括Modicon plc(所有

支持Modbus协议)，也有各种各样的端

设备。

该模块使用一个小的I/O数据区进行数据之间的传输

模块和ControlLogix处理器，使其成为理想的

ControlNet或以太网应用程序与远程机架中的模块。

特点和优点

采用MVI56 Modbus主从通信模块

简化的数据块被设计成允许ControlLogix处理器

接口容易与Modbus协议兼容的设备和主机。

该模块充当Modbus之间的输入/输出模块

网络和ControlLogix处理器。数据从

处理器与Modbus网络上的动作是异步的。

一个5000字的寄存器空间在模块之间交换数据

处理器和Modbus网络。

许多主机SCADA应用程序支持Modbus协议，而

通常支持该协议的设备包括几个plc，如

以及市场上许多其他第三方设备。(

【英文介绍】

Modbus Master/Slave 

Communication Module for Remote 

Chassis 

MVI56-MCMR 

The MVI56 Modbus Master/Slave Communication Module with 

Reduced Data Block allows ControlLogix processors to interface 

easily with other Modbus protocol compatible devices. 

Compatible devices include not only Modicon PLCs (which all 

support the Modbus protocol) but also a wide assortment of end 

devices. 

This module uses a small I/O data area for data transfer between the 

module and the ControlLogix processor, making it ideal for 

ControlNet or Ethernet applications with the module in a remote rack. 

Features and Benefits 

The MVI56 Modbus Master/Slave Communications module with 

reduced data block is designed to allow ControlLogix processors to 

interface easily with Modbus protocol-compatible devices and hosts. 

The module acts as an input/output module between the Modbus 

network and the ControlLogix processor. The data transfer from the 

processor is asynchronous from the actions on the Modbus network. 

A 5000-word register space in the module exchanges data between 

the processor and the Modbus network. 

Many host SCADA applications support the Modbus protocol, while 

devices commonly supporting the protocol include several PLCs, as 

well as many other third party devices in the marketplace. (For a 

partial list of devices that speak Modbus, please visit the ProSoft 

Tested section of the ProSoft Technology web site). 

General Specifications 

• Single Slot - ControlLogix backplane compatible

• Designed especially for remote rack implementations

• The module is recognized as an Input/Output module and has

access to processor memory for data transfer

• Ladder Logic is used for data transfer between module and

processor. Sample Ladder File included

• Configuration data obtained from configuration file downloaded

to module. Sample configuration file included
