Modbus TCP/IP

Communication Module for

CompactLogix®

MVI69-MNET

The inRAx Modbus TCP/IP Communication Module is designed to allow

CompactLogix® /MicroLogix® processors to interface with other Modbus

TCP/IP protocol-compatible devices, including not only Modicon®

processors, but also a wide variety of other Client and server devices.

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.

The module acts as an input/output module between the Modbus TCP/IP

network and the CompactLogix backplane. The data transfer from the

processor is asynchronous from the actions on the Modbus TCP/IP

network. A 5000 16-bit register data space in the module exchanges data

between the processor and the Modbus TCP/IP network.
