Prosoft MVI56-GEC Ethernet Communications Interface Module

Product Dimensions：

The ProSoft Technology MVI56-GEC is a powerful communication module designed to bridge the gap between Allen-Bradley ControlLogix platforms and generic Ethernet devices. It essentially allows a ControlLogix processor to “talk” to any device that supports standard TCP/IP or UDP/IP protocols.

## Product Overview

The MVI56-GEC (Generic Ethernet Communication Module) acts as a gateway. It is specifically used when a device does not use a standard industrial protocol (like EtherNet/IP or Modbus TCP) but instead communicates via raw TCP/IP sockets or UDP/IP. This makes it an essential tool for integrating specialized hardware like barcode scanners, weight scales, or proprietary high-level computer systems.

## Technical Specifications

## Key Advantages

• Highly Flexible: It allows custom messaging strings, meaning you can define exactly how data is packaged and sent to non-standard devices.

• Reduced CPU Overhead: By handling the Ethernet stack processing on the module itself, it prevents the ControlLogix CPU from being bogged down by complex string manipulations.

• Simplified Integration: ProSoft provides Add-On Instructions (AOI) and sample ladder logic, making it much easier to map data into your tags.

• Web-Based Configuration: Includes a built-in web server for diagnostics and monitoring.

## Product Applications

The MVI56-GEC is typically used in scenarios where “standard” industrial protocols aren’t an option:

1. Barcode Scanners & RFID Readers: Sending and receiving ASCII data strings over Ethernet.

2. Vision Systems: Interfacing with high-speed cameras for pass/fail data or coordinate transfers.

3. Weight Scales: Reading precise measurements from industrial scales that output raw data.

4. Database Integration: Communicating with a custom PC-based software (like a MES or ERP system) via sockets.

5. Printer Control: Sending print commands directly to industrial inkjet or label printers.

## Important Considerations & Precautions

• Network Security: Since this module uses raw TCP/UDP, it does not have built-in encryption. Ensure it is placed behind a secure industrial firewall.

• Power Budget: Check your ControlLogix chassis power supply capacity; the 800 mA draw is significant if you have many high-power modules in one rack.

• Firmware Compatibility: Always ensure the module firmware is compatible with your version of Studio 5000 / RSLogix 5000.

• IP Conflicts: Ensure the module has a unique static IP address that does not conflict with the PLC’s CPU or other network devices.
