ProSoft MVI56E-MCMXT Modbus Master/Slave Enhanced Communication Module

Product Introduction

The ProSoft MVI56E-MCMXT is an enhanced Modbus Master/Slave communication module specifically developed for Allen-Bradley ControlLogix processors, with extended environmental capabilities for harsh industrial conditions. As part of the Logix-XT™ platform, this module is engineered to operate reliably in extreme temperatures and demanding environments where standard modules may not perform consistently.

This module functions as a bridge between the ControlLogix backplane and Modbus-compatible devices, supporting both Master and Slave communication modes. It allows the controller to actively poll field devices while also responding to incoming requests, making it suitable for complex and distributed automation architectures.

Equipped with dual Modbus communication ports and a dedicated configuration port, the MVI56E-MCMXT provides flexible connectivity and simplified setup. Its conformal coating enhances resistance to moisture, dust, and corrosive atmospheres, ensuring long-term reliability in industries such as oil & gas, power generation, and heavy manufacturing.
