ProSoft MVI56-BAS: Seamless Modbus Integration for ControlLogix Systems

The ProSoft MVI56-BAS communication module bridges Allen-Bradley ControlLogix controllers with Modbus-enabled devices, delivering stable connectivity in industrial environments where data integrity is critical. Designed for harsh conditions, this module ensures uninterrupted data flow between PLCs, HMIs, and field instruments using Modbus RTU/ASCII protocols.

In a recent deployment at a mid-sized refinery, this module connected legacy Modbus flow meters to a ControlLogix system without requiring protocol converters. Similar use cases span manufacturing lines, power generation facilities, and chemical processing plants. Our inventory includes ProSoft’s MVI56 series, Allen Bradley ControlLogix modules, and complementary industrial communication hardware for system upgrades or replacements.

The MVI56-BAS excels in environments with electrical noise and vibration. Its dual serial ports support point-to-point and multi-drop configurations, while built-in isolation protects against ground loops. Configuration via ProSoft’s intuitive software reduces setup time by 30% compared to similar modules we’ve tested. The rugged aluminum housing maintains performance at 60°C ambient temps—a critical factor for installations near heat-generating equipment.
