ProSoft MVI56E-FLN
1. Overview
The MVI56E-FLN module is one of ProSoft’s enhanced communication modules for Factory Automation (FA) control networks, engineered to meet the intricate communication requirements of industrial automation systems. It is typically deployed to connect Programmable Logic Controllers (PLCs), such as Allen-Bradley ControlLogix, with various devices across FA networks, enabling seamless data transmission and integration.
2. Parameters and Technical Specifications
- Model: MVI56E-FLN
- Weight: Approximately 0.5 kg (varies by configuration)
- Power Supply: DC-powered, compatible with backplane power sources
- Interfaces: Equipped with multiple serial ports, supporting communication protocols including RS-232, RS-422 and RS-485
- Network Compatibility: Supports Ethernet communication, with built-in support for industrial standard protocols such as Modbus and DF1
- Certifications: Complies with ATEX LOC certification (applicable to variants like MVI56E-ILX56), suitable for explosion-proof scenarios
3. Product Features
- Enhanced Communication Capability: Compared with standard communication modules, the MVI56E-FLN delivers superior data processing performance, supporting higher-frequency communication and more complex protocol parsing.
- Bandwidth Optimization: Minimizes backplane and network bandwidth consumption by reducing the need for data block transmission.
- Flexibility: Supports a wide range of communication protocols (e.g., Modbus, DF1) and allows remote configuration and management via control networks.
- Redundancy Support: Can be paired with ControlNet communication adapters and redundant controllers to enhance system reliability.
4. Structure and Components
The module adopts a single-slot design, compatible with the 1756 chassis (ControlLogix platform).
- Backplane Interface: Directly connects to the PLC host controller via the backplane slot.
- Serial Ports: Features multiple serial communication ports for linking field devices in FA networks.
- Indicator Lights: The module front panel is equipped with LED indicators to display network connection status, data transmission status and other operational metrics.
5. Application Areas
- FA Control Networks: Facilitates connectivity between field devices such as sensors and actuators in factory automation control networks.
- Industrial Automation Systems: Widely used in industries including petrochemicals, manufacturing and energy management, enabling integration between PLCs and field networks.
- Remote Data Acquisition: Transmits field data to upper-level computers or cloud platforms for monitoring via Ethernet gateways.
6. Installation and Maintenance
Installation Requirements
- Requires an Allen-Bradley ControlLogix processor and an available slot in the chassis for module installation.
- Ensure the backplane power supply (typically 5V DC at 800mA) is operational during installation.
Configuration Tools
ProSoft’s Configuration Builder (PCB) and Product Discovery Service (PDS) are recommended for parameter configuration. These tools support remote setup via ControlNet networks.
Maintenance Recommendations
- Regularly inspect the integrity of connecting cables (e.g., RS-232/422/485 cables).
- Ensure the module operates within the recommended temperature and humidity range.
- Given its role in industrial communication, firmware upgrades and advanced configuration should be performed under the guidance of professional technical personnel.
