PROSOFT MVI56E-MCM/MCMXT Communication Module

PROSOFT MVI56E-MCM/MCMXT Communication Module

DESCRIPTION

The MVI56E Communication Module allows for Modbus Master and/or Slave  connectivity from Rockwell Automation® ControlLogix® processors to Modbus  RTU/ASCII devices. Each MVI56E port can be configured as a Master or Slave.

The MVI56E-MCM and MVI56E-MCMXT act as input/output modules on the  ControlLogix backplane, making Modbus data appear as I/O data to the processor.  Two independently configurable serial ports can operate on the same or different  Modbus networks. The MVI56E-MCM is designed for standard process  applications and the MVI56E-MCMXT is designed for the Logix-XT™ control  platform, allowing it to operate in extreme environments. It can tolerate higher  operating temperatures, and has conformal coating to protect it from harsh or  caustic conditions.

Benefits

 All MVI56E products are backward-compatible with earlier MVI56 modules allowing direct  replacement without the need to change existing controller programs

 Allows you to gather more data from your devices, which improves operational  performance

 Enjoy Enhanced features and flexibility without incurring expensive reprogramming costs

 Module configuration stored within the RSLogix™ 5000 project (ACD file)

 No additional programming or configuration software is required

 Add-On Instruction for RSLogix 5000 version 16 or higher cuts development time and  costs

 Facilitates remote user access across the ControlLogix backplane through Rockwell  Automation’s 1756-ENBT module

 Configure, diagnose, and analyze process data and communications status

 Bridge through multiple ENBT/CNBT links to connect to MVI56E-MCMs installed in remote  chassis for configuration and diagnostics

 Simplifies adding the module in an RSLogix 5000 project

Configuration

The module configuration is defined in the Add on Instruction. The AOI is fully  commented, and includes user-defined data types, ladder rungs and controller tags. The AOI can be used without modification for most application.

The MVI56E-MCM User Manual and sample configuration provide a quick and easy  example with step-by-step instructions on how to move data through the module from  the Modbus network to the processor.
