Overview of Allen Bradley MVI69-MCM

The Allen Bradley MVI69-MCM is a Modbus Master/Slave network interface module designed for Rockwell Automation® CompactLogix™ and MicroLogix™ 1500 controllers. Manufactured by ProSoft Technology, this communication module enables industrial automation systems to integrate Modbus RTU devices with Allen Bradley programmable logic controllers, supporting both master and slave roles. The MVI69-MCM fits directly into the 1769 backplane, allowing straightforward installation and seamless data exchange between PLCs and Modbus field devices. With its support for industry-standard protocols, the MVI69-MCM is a reliable solution for extending connectivity in automated environments that require legacy or third-party equipment to communicate with modern control platforms.

Key Features of Allen Bradley MVI69-MCM

  • Modbus RTU Master/Slave communication – supports both roles for flexible integration
  • Direct 1769 backplane integration with CompactLogix and MicroLogix 1500 controllers
  • Supports RS232, RS422, and RS485 physical interfaces for wide device compatibility
