ProSoft MVI56E-MNETC Modbus TCP ControlLogix Gateway Module

Product Overview

The ProSoft MVI56E-MNETC is an enhanced communication interface designed to connect Allen-Bradley ControlLogix platforms with Modbus TCP/IP networks. It enables bidirectional data exchange between Ethernet-based industrial devices and PLC control systems without requiring protocol conversion hardware beyond the module itself.

Built on the ProSoft E-Series architecture, the module is optimized for high-throughput applications, supporting simultaneous client and server communication with stable performance under heavy network loads.
