ProSoft MVI69-MNET Modbus TCP/IP Communication Module

Product Introduction

The ProSoft MVI69-MNET is a Modbus TCP/IP Communication Module designed for Allen-Bradley CompactLogix processors, providing reliable Ethernet-based connectivity to Modbus TCP networks. It enables seamless integration between PLC systems and a wide range of Modbus-compatible devices such as HMIs, SCADA systems, remote I/O, and industrial instruments.

This module operates as both a Client and Server, allowing the controller to initiate communication requests while also responding to incoming data queries. It serves as a bridge between the CompactLogix backplane and Ethernet networks, simplifying system architecture and eliminating the need for external gateways.

With high-speed 10/100 Mbps Ethernet communication and dual-port capability, the MVI69-MNET ensures efficient data exchange in modern industrial environments. Its compact single-slot design makes it suitable for applications requiring reliable network communication without occupying excessive panel space.
