ProSoft MVI56E-MCMXT Modbus Communication Module

Product Overview

The ProSoft MVI56E-MCMXT is a high-reliability Modbus communication interface designed for integration with Allen-Bradley ControlLogix platforms. Engineered for demanding operating environments, it enables seamless data exchange between PLC systems and Modbus RTU/ASCII networks.

As part of the XT (Extreme Environment) product line, this module is built with extended temperature tolerance, conformal coating protection, and reinforced electrical isolation to ensure stable operation in harsh industrial conditions such as oil fields, mining operations, and power infrastructure.

It supports simultaneous Modbus Master and Slave functionality, allowing flexible network architecture without additional hardware.

Communication Capabilities

• Protocol Support: Modbus RTU and Modbus ASCII

• Operating Modes: Master, Slave, or combined Master/Slave

• Serial Interfaces: Dual isolated RS-232 / RS-422 / RS-485 ports

• Baud Rate Range: 110 bps to 115.2 kbps

• Node Address Range: 1 to 247

Master functionality supports configurable polling strategies and up to 325 commands per port, enabling high-density device communication.

Slave functionality exposes up to 10,000 registers for external Modbus masters, supporting both integer and floating-point data formats.

ControlLogix Integration

• Backplane Communication: High-speed optimized data transfer

• Slot Requirement: Single ControlLogix slot

• Rack Support: Local or remote chassis configurations

• Backplane Current Draw: 800 mA @ 5 VDC

Designed for native compatibility with Allen-Bradley ControlLogix processors without requiring additional bridging hardware.
