ProSoft MVI56-MBP Modbus Plus Protocol Interface Module

ProSoft MVI56-MBP ControlLogix Modbus Plus Communication Module

Product Description

The MVI56-MBP (MVI56-MBP) is a specialized Modbus Plus communication gateway developed by ProSoft Technology for the Allen-Bradley ControlLogix platform. This single-slot module resides directly in the 1756 chassis, enabling high-speed, bi-directional data transfer between ControlLogix processors and Modbus Plus networks. It is the primary solution for integrating modern Rockwell Automation systems with legacy Modicon PLCs and other Modbus Plus compatible hardware.

The MVI56-MBP (MVI56-MBP) supports both Master and Slave functionalities across two independent ports. It utilizes a large 4000-word shared data memory, allowing for complex mapping of bits, integers, and floating-point values. With support for Global Data, the module ensures high-speed deterministic control with response times often under 5 ms, making it suitable for time-critical process control and SCADA applications.
