Information About MVI69-MCM

The MVI69-MCM is a versatile Modbus Master/Slave communication module designed by ProSoft Technology for seamless integration with Allen-Bradley CompactLogix™ and MicroLogix™ 1500 controllers. It enables Rockwell PLCs to communicate with Modbus-compatible devices using Modbus RTU/ASCII protocols over serial connections. With dual configurable ports, broad protocol support, and robust diagnostics, the MVI69-MCM is ideal for connecting PLCs with third-party Modbus sensors, drives, meters, and remote systems in industrial automation networks.

Key Features:

• Compatibility: Allen-Bradley CompactLogix and MicroLogix 1500 platforms

• Protocol Support: Modbus RTU and ASCII (Master and Slave modes)

• Communication Ports: 2 x isolated serial ports (RS-232, RS-485, RS-422)

• Baud Rate Range: 110 to 115,200 bps

• Supported Devices: Up to 100 Modbus slaves (master mode), 30 Modbus masters (slave mode)

• Configuration Interface: Ladder logic-based with user-defined function blocks

• Diagnostics: LED indicators and onboard diagnostics for real-time monitoring

• Power Source: Backplane-powered via CompactLogix rack

• Form Factor: Compact 1769-style slot module for easy integration

• Application Scope: Industrial automation, legacy device integration, SCADA systems

This communication module is ideal for control engineers and system integrators who need a reliable, high-performance solution for bridging CompactLogix controllers with Modbus networks, especially in complex industrial environments such as oil & gas, water treatment, and manufacturing.
