The ProSoft Technology MVI56-MCM Communication Module

is an in-chassis industrial communication module designed for Rockwell ControlLogix PLC systems. It provides seamless integration between the ControlLogix platform and devices using the Modbus RTU and ASCII serial communication protocols.

This module acts as a Modbus Master or Slave interface, enabling the PLC to communicate with external field devices such as sensors, drives, meters, and third-party controllers. It installs directly into the ControlLogix rack and operates as an I/O module on the backplane, exchanging data with the processor in real time.

The MVI56-MCM features two configurable serial ports, each capable of operating independently as a master or slave, allowing connection to multiple Modbus networks simultaneously.

It supports a large internal memory structure (data registers) to manage communication between the PLC and Modbus devices. Data exchange is handled asynchronously, meaning the PLC logic execution is not interrupted by communication delays.

This module is widely used in applications where integration between different communication protocols is required, especially in legacy systems where Modbus devices must interface with modern PLCs.
