PROSOFT MVI56E-MCM Communication Module – ASCII Compatible Modbus Master/Slave Module

This communication module bridges legacy systems with modern industrial networks through its Modbus protocol support. Designed for seamless integration with Allen Bradley PLCs, it handles complex data exchanges while maintaining backward compatibility with older MVI56 modules. The ASCII format compatibility ensures smooth operation in mixed-protocol environments.

Commonly used in oil and gas pipelines, water treatment plants, and manufacturing facilities, this module connects programmable logic controllers with SCADA systems. Our inventory includes related Prosoft models like MVI56E-MCM, along with compatible Allen Bradley components and Schneider Modbus converters. One client mentioned improved data acquisition speed in their food processing plant’s temperature control system after upgrading to this module.

The module’s configuration flexibility stands out – using either the debug port or user-defined files maintains settings during power cycles. Its 16-bit integer handling works with Enron/Daniel® implementations, while floating-point support reduces data conversion errors. Compared to earlier versions, the smaller data blocks actually improved network efficiency in a recent wastewater treatment project. Personally, I found the ASCII compatibility particularly useful when integrating third-party sensors into legacy control systems.
