The MVI56-MCMR is a Modbus Master/Slave module for ControlLogix, optimized for remote rack applications (ControlNet) by using a reduced 42-word I/O mapping.

How do I prevent data from resetting to 0 during a power loss?

You can use the Initialize Input Image parameter to cache values from the processor so they are not reset to zero during a module reset or power loss.

How do I set the serial port (RS-232/422/485)?

Jumpers are located at the bottom of the module labeled COM1, COM2, and Setup, allowing you to select the physical standard.

What is the pass-thru difference?

While the MCM supports pass-through for mapping read/write commands, the MCMR requires reading from one address range and writing to another if configured as a slave.

How to configure the module?

The MVI56(E)-MCMR is configured via ProSoft Configuration Builder (PCB) and uses ladder logic Add-On Instructions (AOI) for integration into RSLogix 5000.

Features:

Communication module
ControlLogix
Modbus Communication Module with Reduced Data Block

Specific to the ControlLogix series, the MVI56-MCMR serves as a communication module that supports Modbus protocol functionality. It is versatile in its operation, with the ability to function effectively within a temperature spectrum of 0 to 60 °C. This compact module requires installation in one slot of a remote rack.

The module operates with a significant backplane current draw of 800 mA at 5 VDC, while minimal power consumption is noted at just 3 mA when using a 24 VDC supply. The design necessitates a minimum phase wire size of 1.3 mm², ensuring compatibility across various wiring configurations.

For connectivity, the MVI56-MCMR module incorporates LED indicators that assist in providing visual status updates. Additionally, it supports multiple communication interfaces such as RS-232, RS-485, and RS-422, allowing a baud rate range from 110 baud up to 115200 baud, making it adaptable for different networking needs.

The MVI56-MCMR ProSoft Communication Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The ProSoft Technology MVI56-MCMR (and enhanced MVI56E-MCMR) is a Modbus Master/Slave module for Rockwell Automation ControlLogix, specifically optimized for remote chassis applications using ControlNet. It uses a reduced 42-word Input/Output image (compared to the 250-word MVI56-MCM) to minimize bandwidth impact, with two configurable serial ports supporting RS-232, 422, and 485

Water and Wastewater: Manages processes by exchanging data between control systems and remote monitoring stations.
Food Processing: Used in automated production lines for monitoring and control.
Oil and Gas: Integration in pipelines and offshore platforms for remote data acquisition.
Mining, Pulp, and Paper: Connects disparate legacy equipment to modern ControlLogix systems in harsh environments.

This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.

Data Block Size: The MVI56-MCM uses a large 250-word input and 248-word output mapping. The MVI56-MCMR

Network Optimization: The MCMR is specifically designed for ControlNet applications. Its smaller I/O size is easier to schedule in RSNetworx and has a lower impact on other remote I/O bandwidth.

Configuration Method: The MCM is typically configured via ladder logic controller tags. The MCMR is configured using an offline file created in ProSoft Configuration Builder (PCB).

Pass-Thru Feature: Only the MCM supports Modbus Pass-Thru, which allows a master to issue Read and Write commands to the same address. On the MCMR, you must use separate address ranges for Read and Write operations.
