Key Features and Advantages
The **MVI56-MCM** enables seamless integration of ControlLogix PLCs with Modbus networks. Its dual-interface design supports simultaneous operation as a Modbus TCP master and RTU slave. Built-in galvanic isolation (2,500 Vrms) protects against ground loops, while configurable message queuing optimizes PLC scan times. ProSoft’s **Configuration Studio** software simplifies tag mapping with pre-defined AOIs (Add-On Instructions) for rapid deployment.
Non-volatile memory retains configurations during power loss, and hot-swappable design minimizes downtime. The module supports up to 247 Modbus devices per port, with dynamic address translation for legacy systems. Rugged construction includes surge suppression (IEC 61000-4-5) and conformal coating for harsh environments.
Application Areas
Application AreasIndustrial automation bridging ControlLogix with Modbus devices (e.g., meters, HMIs, drives). Water/wastewater SCADA systems, oil & gas RTU networks, and building management systems. Used in energy monitoring, HVAC control, and legacy equipment retrofits.

Installation and Configuration
**Installation**: Insert into ControlLogix chassis (slot 0-17). Terminate RS-485 networks with 120Ω resistors. Use shielded CAT5e/CAT6 for Ethernet. Ground shields at one end for noise immunity.
**Configuration**: Import AOIs into Studio 5000. Define data maps in Configuration Studio. Assign IP addresses via DHCP or static setup. Validate with built-in diagnostic LEDs (Port Status, Error).
Maintenance and Diagnostics
Monitor communication health via **ProSoft Message Monitor**. Update firmware via Ethernet or SD card. Clean terminals annually with isopropyl alcohol. Replace backup battery (CR2032) every 5 years.
Product Assurance
ProSoft provides a 3-year warranty with 24/7 technical support. The MVI56-MCM undergoes 500-hour burn-in testing and complies with IEC 61131-2 for industrial environments. SIL 2 certification available for safety-critical applications.
Note: Verify Modbus register mapping with slave devices. Use ProSoft’s **MVI56-MCM-GS** Getting Started Guide for detailed wiring diagrams.
