The MVI56E-MNET is a specialized Modbus communication module developed by ProSoft Technology, designed for seamless integration with Allen-Bradley ControlLogix programmable logic controllers (PLCs). It enables reliable data exchange between ControlLogix systems and Modbus-enabled devices, bridging the gap between different industrial communication protocols.
- Brand: ProSoft Technology
- Product Series: MVI56E (Enhanced Communication Modules for ControlLogix)
- Form Factor: 17-slot ControlLogix chassis-compatible, following Allen-Bradley’s modular design standards
- Power Requirement: Draws power from the ControlLogix chassis backplane (no external power supply needed)
- Terminal Interface: 2 x RJ45 ports (for Modbus TCP/IP communication) and optional terminal blocks for Modbus RTU (via RS-232/RS-485, depending on model variant)
- Supported Protocols:
- Modbus TCP/IP (client and server modes)
- Modbus RTU (master and slave modes, if equipped with serial interface)
- Data Transfer Rate:
- Ethernet (Modbus TCP/IP): Up to 100 Mbps (auto-sensing 10/100 Base-T)
- Serial (Modbus RTU): Up to 115.2 kbps (configurable baud rate, parity, and stop bits)
- Data Capacity: Supports up to 4,000 input registers and 4,000 output registers for data mapping between ControlLogix and Modbus devices
- Connection Limits: Up to 32 simultaneous Modbus TCP/IP client connections (for communication with multiple Modbus servers)
- Operating Temperature: 0°C to 60°C (32°F to 140°F)
- Storage Temperature: -40°C to 85°C (-40°F to 185°F)
- Relative Humidity: 5% to 95% (non-condensing)
- Isolation: 1500 V DC between Ethernet ports and backplane; 250 V DC between serial ports (if applicable) and backplane
- Certifications: UL 508 (Industrial Control Equipment), CSA C22.2 No. 14-15, CE (EN 61000-6-2, EN 61000-6-4), ATEX Zone 2/22 (for hazardous area variants)
- Dual-Role Flexibility: Acts as both Modbus master/client and slave/server, adapting to diverse network architectures.
- Seamless Chassis Integration: Communicates with the ControlLogix processor via the chassis backplane, eliminating the need for external wiring between the module and PLC.
- Configurable Data Mapping: Allows users to define custom register maps (via ProSoft Configuration Builder software) to align with specific application data requirements.
- Diagnostic Tools: Built-in status LEDs (power, backplane communication, Ethernet activity) and software-based diagnostics for troubleshooting network issues.
- Redundancy Support: Compatible with ControlLogix redundant chassis setups, ensuring uninterrupted communication in critical applications.
Ideal for industrial automation systems requiring Modbus communication with ControlLogix PLCs, such as:
- Data exchange with Modbus RTU sensors (e.g., temperature, pressure sensors) in manufacturing lines
- Integration of ControlLogix with Modbus TCP/IP SCADA systems for centralized monitoring
- Communication with Modbus-enabled variable frequency drives (VFDs) or motor controllers in HVAC systems
- Data transfer between ControlLogix and third-party industrial devices (e.g., meters, actuators) in oil and gas, water/wastewater, or food processing industries
