Description

The ProSoft MVI56E-MCMXT is an enhanced Modbus Master/Slave communication module specifically engineered for the Rockwell Automation ControlLogix-XT platform. This module enables ControlLogix processors to interface seamlessly with devices utilizing Modbus RTU or ASCII serial protocols. As a member of the XT (Extended Temperature) series, the MVI56E-MCMXT is designed for deployment in harsh industrial environments, featuring conformal coating for protection against caustic or humid conditions and an expanded operating temperature range.

Features

  • CIPconnect enabled for module and network configuration via 1756-ENxT modules with EtherNet/IP pass-through.
  • Supports Enron Modbus protocol for floating-point data transactions.
  • Integrated 4-digit LED display for real-time status and diagnostic information.
  • Onboard Modbus network analyzer for simplified troubleshooting.
  • Two independently configurable serial ports capable of operating as Modbus Master or Slave.
  • Shared 10,000-word user-controlled database.

Applications

  • Oil & Gas: SCADA interfacing, flow computers, and lift system monitoring.
  • Power & Energy: Turbine control, excitation systems, and protective relay integration.
  • Water & Wastewater: Pump station monitoring and outdoor cabinet installations.
  • Manufacturing: Integration of Motor Control Centers (MCCs), Variable Frequency Drives (VFDs), and instrumentation.
  • Remote Automation: Harsh-environment rated for offshore, mining, and pipeline infrastructure.

Installation Guidelines

  • Ensure the ControlLogix rack is powered down before inserting or removing the module.
  • Seat the module firmly into the chassis slot and secure the top and bottom retaining screws to ensure proper grounding and mechanical stability.
  • Use shielded twisted-pair cabling for all serial connections to minimize EMI interference.
  • Maintain proper ventilation within the cabinet; although rated for higher temperatures, ensure airflow is not obstructed.
  • Handle with care to avoid damaging the conformal coating on the PCB.
  • Configuration is managed via controller-scoped tags in Studio 5000 / RSLogix 5000 using the provided Add-On Instruction (AOI).

FAQ

What is the MVI56E-MCMXT?

The ProSoft MVI56E-MCMXT is an enhanced Modbus Master/Slave communication module designed for the ControlLogix platform, specifically for extreme environments.

Is it backwards compatible with the older MVI56-MCM?

Yes. The MVI56E-MCMXT is designed as a drop-in replacement. For most applications, you can replace a legacy module by transferring the configuration through the PLC ladder logic.

What does the XT stand for?

XT refers to the Extended Temperature version. It features conformal coating to protect against harsh or caustic conditions and can operate in temperatures ranging from -25 degC to 70 degC, compared to the standard model's 0 degC to 60 degC range.

Do the serial ports have electrical isolation?

The two application serial ports provide 1000 volts of electrical isolation between the port and the ControlLogix backplane. There is no isolation between the ports themselves or between the debug/configuration port and the module's internal circuitry.
