ProSoft ILX34‑MBS485‑ Modbus RTU RS‑485 Serial Communication Module

2. Product Overview

The ILX34‑MBS485 is Point‑I/O form‑factor Modbus serial module for Rockwell CompactLogix L1 controllers and 1734 distributed Point‑I/O system. It acts as protocol gateway between PLC backplane and Modbus‑RTU field devices over RS‑485 interface, supporting both Master and Slave operation modes. Built‑in diagnostic counters capture communication fault status directly inside controller tags. It reduces retrofitting work when integrating legacy Modbus instruments, drives and sensors into modern Logix‑based automation systems. ILX34‑MBS485 is used as drop‑in spare for cabinet maintenance and system expansion projects.
