ProSoft MVI69-MNET Modbus TCP/IP Communication Module
MVI69-MNET is an inRAx single-slot Modbus TCP communication adapter developed by ProSoft Technology, compatible with Rockwell CompactLogix 1769 series and MicroLogix 1500 LRP PLC racks. It acts as a protocol gateway, enabling bidirectional data exchange between Logix controllers and Modbus TCP third-party devices including flow meters, inverters, thermal instruments and remote SCADA systems.
This module equips dual independent 10/100Mbps Ethernet RJ45 ports, supporting both Modbus TCP Client and Server modes with up to 100 client commands and 5000 16-bit register data cache. It comes with AOI add-on instructions and web diagnostic page, supporting hot-swap installation without rack power cut, widely used as spare replacement for factory automation Modbus interconnection maintenance and system expansion projects.
