OverviewUnlock the full potential of your existing industrial automation infrastructure with the ProSoft MVI56-BAS BASIC Communication Module. Engineered specifically for Allen-Bradley ControlLogix platforms, this powerful single-slot module provides a crucial bridge for integrating legacy BASIC programs from 1771-DB and 1747-BAS systems. The MVI56-BAS streamlines the modernization process, allowing for efficient data exchange between your ControlLogix processors and a wide array of external devices using versatile ASCII or DF1 protocols. This not only preserves your valuable legacy software investments but also enhances the overall adaptability and functionality of your control systems, ensuring a smooth transition to contemporary industrial environments without extensive re-engineering.Key Features Legacy Program Integration: Effortlessly migrate and execute existing 1771-DB and 1747-BAS BASIC programs directly within modern ControlLogix environments, safeguarding your foundational software assets. Versatile Communication Ports: Equipped with a dedicated RS-232 serial configuration (CFG) port, PRT1 for ASCII communication or program downloads, and PRT2 for flexible ASCII or DF1 communication, catering to diverse connectivity needs. Robust Programming Language: Supports BASIC-52, offering a familiar and powerful environment for developing custom applications and specialized data handling routines. Optimized Memory & Storage: Features 24,064 bytes of RAM for efficient program execution and a Compact Flash disk for convenient program backup, transfer, and secure storage. Flexible DF1 Communication: Configurable as either a full-duplex device or a half-duplex slave, providing adaptable communication options to suit various network architectures. DH-485 Interfacing: Seamlessly interfaces your ControlLogix processor with a broad range of DH-485 devices, requiring only the addition of a Rockwell Automation AIC+ device. Intuitive Data Transfer: Utilizes standard ladder logic for straightforward and reliable data exchange between the module and the ControlLogix processor. Comprehensive LED Indicators: Provides real-time status updates through dedicated LEDs for module status, backplane transfer activity, application status, and serial communication activity, enabling quick diagnostics.
