MVI56-MCM | Modbus Plus Communication Module

Key Features and Advantages

Seamless ControlLogix Integration: The MVI56-MCM installs directly into ControlLogix chassis as a local module, enabling native Modbus Plus communication without external gateways or additional controllers.

High-Performance Data Exchange: Capable of processing up to 500 registers per second, this module ensures real-time data synchronization between ControlLogix processors and Modbus Plus devices.

Flexible Network Configuration: Supports both token passing and polling modes, allowing the MVI56-MCM to function as a node on existing Modbus Plus networks or create new networks.

Robust Diagnostics: Comprehensive status indicators and detailed error reporting simplify troubleshooting. The module continuously monitors network health and automatically recovers from transmission errors.

Easy Programming: Configuration through Rockwell Studio 5000 using Prosoft’s intuitive add-on instructions (AOIs) eliminates the need for separate configuration software.

Application Fields

The MVI56-MCM enables seamless integration of legacy Modbus Plus devices into modern ControlLogix systems across multiple industries. In water treatment facilities, it connects legacy PLCs, flow meters, and pump controllers to centralized SCADA platforms. Manufacturing plants utilize this module to integrate older machinery, HMIs, and process controllers into modern automation networks.

Energy management applications include substation monitoring where the MVI56-MCM interfaces with protective relays and power meters. Building automation systems leverage this module to connect legacy HVAC controllers and lighting systems to central management platforms. Its rugged design makes it suitable for harsh environments like mining operations and oil fields where legacy Modbus Plus devices require integration with modern control systems.

Installation and Maintenance

Installation Preparation: Before installing the MVI56-MCM, verify compatible ControlLogix chassis and firmware versions. Configure the module slot in Studio 5000 and download the Prosoft add-on instructions. Ensure proper termination of the Modbus Plus network and use shielded twisted-pair cables with correct impedance.

Maintenance Recommendations: Monitor network status through the module’s diagnostic tags in the ControlLogix program. Perform firmware updates during scheduled maintenance windows using Prosoft’s update tools. Clean the module’s ventilation slots annually using low-pressure compressed air. For optimal performance of the MVI56-MCM, verify network parameters match existing Modbus Plus devices after any system changes.
