Introduction to ProSoft MVI46-MNET
MVI46-MNET Product Overview
The ProSoft MVI46-MNET is a dedicated Ethernet communication module developed by ProSoft Technology, a leading provider of industrial connectivity solutions. Specifically engineered to bridge the compatibility gap between Allen-Bradley SLC 500 and MicroLogix 1500 programmable logic controllers (PLCs) and Modbus TCP/IP-based industrial networks, it serves as a critical communication hub in small-to-medium manufacturing cells, water treatment facilities, and food processing lines. A key value proposition is its ability to extend the lifespan of legacy serial-centric PLCs by enabling them to interact with modern Modbus TCP devices—such as remote sensors, SCADA systems, and third-party VFDs—without requiring costly PLC replacements. Operating as both Modbus client and server, it supports asynchronous data transfer between the PLC backplane and Ethernet network, with a 5000-word register space facilitating efficient data exchange.
