ProSoft MVI56-MCM Modbus Communication Module

Description

Integrating Modbus serial connectivity into Rockwell Automation ControlLogix systems is simplified using the MVI56-MCM Modbus Master/Slave Communication Module. This high-performance backplane-compatible module allows ControlLogix processors to interface seamlessly with Modbus RTU and Modbus ASCII protocols. Operating as either a Master or a Slave, the module facilitates direct high-speed data transfer across the ControlLogix backplane, eliminating the need for external protocol gateways and optimizing industrial automation networks.

The MVI56-MCM features dual independent serial ports, providing highly flexible configuration options for complex multi-device networks. By utilizing user-defined data tables and dedicated system memory, it enables robust supervisory control and data acquisition across diverse industrial environments.

Features

• Direct slot-in compatibility with Rockwell Automation ControlLogix chassis.
• Dual independent communication ports configurable as Modbus Master or Modbus Slave.
• Supports both Modbus RTU and Modbus ASCII transmission modes.
• Configurable parameters for baud rates, parity, data bits, and stop bits per port.
• Data transfer via I/O connection to the ControlLogix processor for rapid synchronization.
• Diagnostic and status tracking data accessible directly within processor memory.

Applications

• SCADA and HMI integration with industrial field devices.
• Power monitoring, metering, and energy distribution management.
• Coordination and monitoring of variable frequency drives (VFDs) and motor controllers.
• Remote telemetry unit (RTU) interface and flow computer data aggregation.
• Chemical processing, oil and gas, and water/wastewater plant automation.

Installation Guidelines

Before installing the module, ensure the ControlLogix chassis power supply is completely switched off. Insert the MVI56-MCM into any available slot in the chassis, ensuring the module connector pins align perfectly with the backplane. Secure the module by tightening the mounting screws.

To prevent electrical interference and preserve communication integrity, use high-quality shielded twisted-pair cables for all RS-232, RS-422, or RS-485 serial connections, and verify that the shield is properly grounded at a single point.
