The ProSoft MVI94-MCM is a high-performance Modbus communication module designed for the Allen-Bradley FLEX I/O (1794 rack) platform. Supporting Modbus RTU/ASCII protocols, it can operate flexibly as a Modbus master or slave. This module exchanges data in real-time with the FLEX PLC via the rack backplane and communicates directly with Modbus field devices without the need for an additional gateway, significantly simplifying industrial automation system integration and wiring complexity.
The module is equipped with dual serial ports: PRT1 for configuration and status diagnostics, and PRT2 for application communication. It supports multiple physical layers including RS-232/422/485 and provides 500V optical isolation, enhancing anti-interference capabilities and data reliability. The MVI94-MCM supports up to 5000 Modbus registers and floating-point data types, meeting the needs of large-scale data acquisition and control, and is suitable for integration with high-precision instruments, frequency converters, or smart sensors. The module is designed to meet industrial-grade reliability requirements, operating at temperatures of 0–55°C and humidity of 5–95% RH (non-condensing). It features shock and vibration protection and uses LED status indicators to visually display module status, backplane communication, and serial activity, facilitating on-site commissioning and maintenance.
The MVI94-MCM provides a stable, efficient, and reliable bridging solution between FLEX I/O systems and Modbus network devices, offering significant advantages in performance, scalability, and maintainability for industrial automation projects.

FAQS
The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What length of Modbus bus does the MVI94-MCM support?
The length varies depending on the serial port physical layer. RS-232/422/485 buses have different lengths and must comply with protocol specifications and wiring standards.
Will the configuration be lost upon power failure?
The configuration is stored in non-volatile memory and will not be lost, but real-time data will be lost.
Is the module suitable for high-temperature environments?
Operating temperature is 0–55°C. Exceeding this range may affect performance.
Can it be directly connected to Modbus TCP devices?
The MVI94-MCM only supports serial Modbus RTU/ASCII. TCP requires a gateway or other ProSoft modules.
