MVI94-MCM ProSoft Flex I/O Modbus Gateway 2-Port Serial

ProSoft MVI94-MCM Modbus Master/Slave Flex I/O Network Interface Module

Product Overview

The ProSoft MVI94-MCM is a rugged, single-slot Modbus communication interface designed specifically for the Allen-Bradley 1794 Flex I/O platform. It acts as a gateway between Flex processors and Modbus RTU/ASCII-enabled devices. By emulating either a Modbus Master or Slave, the MVI94-MCM allows for the seamless integration of energy meters, motor drives, and specialized controllers into a Rockwell Automation ecosystem. A key advantage of this module is its internal database of 5,000 registers, which enables high-volume data exchange without straining the main processor's scan time.

Industrial Application Scenarios

• Distributed Power Monitoring: Gathering real-time voltage and current data from multiple Modbus power meters distributed across a facility using the 1794 Flex I/O footprint.

• Oil & Gas Telemetry: Utilizing the Enron Modbus support for high-precision floating-point data transactions common in flow computers.

• HVAC Control Systems: Interfacing local Flex I/O racks with third-party Modbus chillers and boilers.

• Chemical Dosing: Precise control of Modbus-based dosing pumps and analytical sensors in a distributed I/O architecture.
