Overview
The MVI69-MCM is a Modbus communication module designed for Rockwell CompactLogix and MicroLogix™ 1400/1500 platforms. It provides a practical way to integrate Modbus serial devices into Logix-based control systems without adding external gateways or rewriting automation programs. This module is commonly used in applications where equipment from different vendors must exchange data reliably through Modbus RTU or Modbus ASCII protocols.
