MVI56E-MCMR

ControlLogix Enhanced Modbus Master/Slave Communications Interface Module with Reduced Data Block

MVI56E-MCMR

The MVI56E-MCMR Enhanced Modbus Master/Slave Communication Module with Reduced Data Block allows Rockwell Automation® ControlLogix® processors to easily interface with devices using the Modbus RTU/ASCII serial communications protocol. Compatible devices include a wide variety of instruments, process measurement devices, popular brands of programmable logic controllers (PLCs) and programmable automation controllers (PACs).

The MVI56E-MCMR acts as an input/output module on the ControlLogix backplane, making Modbus data appear as I/O data to the processor. Backplane data transfers to and from the processor are asynchronous from communications on the Modbus network. Two independently-configurable serial ports can operate on the same or different Modbus networks. Each port can be configured as a Modbus Master or Slave, sharing the same user-controlled 5000-word database.

The MVI56E-MCMR 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 ControlNet™. For EtherNet/IP™ applications where bandwidth is not an issue, it is strongly recommended to use the MVI56E- MCM.

Funktionen und Vorteile

Features

Benefits

Backward Compatibility

  • All MVI56E products are backward-compatible allowing direct replacement of earlier MVI56 modules without the need to change existing controller programs
  • Enjoy Enhanced features and flexibility without incurring expensive reprogramming costs

Reduced Data Block

  • Reduced Data Block implementation requires less backplane/network bandwidth
  • Smaller data blocks are easier to schedule and transfer on ControlNet networks
  • Ideal solution for remote chassis installations using ControlNet and redundant controllers

CIPconnect-enabled

  • ProSoft Configuration Builder software (PCB), with CIPconnect, facilitates remote user access across the ControlLogix backplane through Rockwell Automation's 1756-ENBT module
  • Configure, diagnose, and analyze process data and communications status
  • CIPconnect can bridge through multiple ENBT/CNBT links to connect to MVI56E-MCMRs installed in remote chassis for configuration and diagnostics

4-digit LED display

  • See critical configuration and status information without having to hook up to the ports

Konfiguration

ProSoft Configuration Builder (PCB) provides a graphical configuration tool for quick and easy management of module configuration files, as well as viewing communication and module diagnostic information.

CIPconnect technology routes connections over multiple EtherNet/IP or ControlNet paths, allowing you to manage the module from remote locations.

The MVI56E-MCMR Setup Guide, with the sample configuration, provides step-by-step instructions on how to move data through the module from the  network to the processor.
