Overview
The MVI69-MNET module is a single-slot solution that provides a powerful connection between Rockwell Automation® CompactLogix processors and Modbus TCP/IP network applications. The Modbus TCP/IP network applications include those networks hosted by Modicon Quantum processors, networks controlled by operator interface software applications, and the growing number of manufactured devices that support this protocol.
