1. Overview and Core Functions

2. Key Technical Parameters

• Communication Interfaces: Supports EtherNet/IP communication (for connection with ControlLogix) and optional Modbus interface (for SCADA communication or remote monitoring).
• Operating Temperature Range: Typically supports -40°C to +85°C, suitable for harsh industrial environments.
• Module Configuration: Performs on-site signal acquisition through a dedicated DAU (Data Acquisition Unit), supporting multiple analog signal (current/voltage) inputs.
• Certifications: In regions such as Canada, some models (e.g., MVI56-AFC) have obtained metrological certification.

3. Product Features

• Reduces PLC Load: Offloads complex calculation logic through hardware, freeing up CPU resources of the ControlLogix main processor.
• High Flexibility: Supports on-site parameterization configuration, capable of handling multiple flow meter principles and calibration curves.
• Multi-Protocol Support: In addition to EtherNet/IP, some models support industrial communication protocols such as Modbus RTU/ASCII and Modbus TCP/IP.
• Modular Design: Connects to the DAU via a dedicated communication module (e.g., MVI56E-MCMR) to achieve flexible on-site deployment.

4. Structure and Composition

• Main Module (MVI56E): Installed in the ControlLogix I/O cabinet, responsible for communication with the PLC.
• Communication Module (e.g., MVI56E-MCMR): Provides a communication bridge between the on-site and the control cabinet, supporting Modbus or EtherNet/IP communication.
• DAU (Data Acquisition Unit): An on-site installed unit responsible for collecting flow meter signals and performing real-time calculations.
• EAFC Manager Software: Used for configuring flow calculation parameters, generating reports, and monitoring operating status.

5. Application Areas

• Energy and Utilities: Oil, natural gas, water supply, and wastewater treatment.
• Petrochemical and Chemical Industry: Accurate monitoring of raw material and product flow rates.
• Manufacturing Industry: Process control and metering of liquids and gases.

6. Installation and Maintenance

6.1 Installation Method

6.2 Maintenance Points

• Regular Calibration: The flow meter system requires regular calibration to ensure calculation accuracy.
• Software Updates: Perform firmware and software updates and maintenance via EAFC Manager.
• Environmental Inspection: Check the protection level and the sealing condition of protective doors (if applicable) to ensure that internal electronic components are not affected by the environment.
