MVI56E-MCMR - Master/Slave Communications Interface Module

Description

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.

Features and Benefits

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

Configuration 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.

Specifications • Backward-compatible with previous MVI56-MCMR version • Single Slot - 1756 ControlLogix® backplane compatible • 10/100 MB Ethernet port for configuration with Auto Cable Crossover Detection • User-definable module data memory mapping of up to 5000 16-bit registers • CIPconnect®-enabled network configuration and diagnostics monitoring using ControlLogix 1756-ENxT modules and EtherNet/IP® pass-thru communications • Sample Ladder Logic or Add-On Instruction (AOI) used for data transfers between module and processor • 4-character scrolling LED display of status and diagnostic data in plain English • ProSoft Discovery Service (PDS) software finds the module on the network and assigns a temporary IP address to facilitate module access and configuration • Personality Module (non-volatile CF card) to store all configuration settings, allowing quick in-the-field product replacement by transferring the CF card
