ProSoft MVI69E-MBTCP CompactLogix Modbus TCP Gateway Module

Product Overview

The ProSoft MVI69E-MBTCP is a CompactLogix-compatible communication module that enables seamless Modbus TCP/IP integration for Allen-Bradley 1769 platform controllers. It is engineered to bridge CompactLogix processors with external Modbus TCP devices such as field instruments, drives, analyzers, and distributed control systems.

This module belongs to the Enhanced (E-Series) architecture, providing improved processing throughput, expanded memory handling, and enhanced diagnostics compared to standard ProSoft communication modules.
