Description

The ProSoft MVI56E-MCM is an enhanced communication module designed to provide seamless Modbus Master and/or Slave connectivity between Rockwell Automation ControlLogix processors and Modbus RTU/ASCII devices. By acting as an I/O module on the ControlLogix backplane, it allows Modbus data to be mapped directly as I/O data, simplifying integration into existing control architectures.

The module features two independently configurable serial ports that can operate on the same or different Modbus networks. It is engineered for standard process applications, offering robust performance for industrial data exchange.

Features

  • Single-slot 1756 ControlLogix backplane compatibility.
  • Two independently configurable serial ports (RS-232, RS-422, or RS-485 via jumper selection).
  • Integrated 10/100 Mbps Ethernet port for configuration, diagnostics, and firmware updates with Auto Cable Crossover Detection.
  • Supports Enron Modbus protocol for efficient floating-point data transactions.
  • Advanced diagnostics including a built-in Modbus network analyzer, communication error counters, and a scrolling alphanumeric LED display.
  • User-defined database supporting up to 10,000 16-bit registers.

Applications

  • Oil & Gas: Integration of remote terminal units (RTU), flow meters, wellhead controllers, and chromatographs.
  • Power & Energy: Connectivity for multi-functional meters, protection relays, variable frequency drives (VFDs), and intelligent circuit breakers.
  • Water & Wastewater: Monitoring and control of pump stations, level sensors, dissolved oxygen sensors, and chemical dosing systems.
  • Manufacturing: Interfacing with third-party sensors, actuators, weighing displays, and small-scale PLCs.

Installation Guidelines

  • Power Down: Always ensure the Rockwell Automation ControlLogix chassis is powered off before inserting or removing the module to prevent electrical damage.
  • Mounting: Carefully align the module with the chassis guides and slide it into the desired slot until it clicks securely into place. Tighten the top and bottom retaining screws to ensure proper grounding and mechanical stability.
  • Power Budget: The module draws 800 mA at 5.1 VDC from the backplane; verify that your chassis power supply has sufficient capacity for this load.
  • Wiring: Use shielded communication cables for serial connections to minimize EMI interference. Ensure proper termination for RS-485/422 networks.

FAQs

What is the MVI56E-MCM?

It is an enhanced Modbus Master/Slave communication module designed specifically for the Rockwell Automation ControlLogix platform.

How is the module configured?

Configuration is performed using Add-On Instructions (AOI) within the RSLogix 5000 or Studio 5000 environment, with parameters stored directly in the project file.

Is the module backwards compatible?

Yes, revision 3 firmware modules are backward compatible with revision 2 AOI or ladder logic, allowing for seamless replacement without requiring code changes.
