The MVI56E-GSC is a high-performance communication module by Allen-Bradley, designed for seamless integration of programmable automation controllers with serial devices through general ASCII interfaces. This module enhances connectivity by adding two configurable serial communication ports to a ControlLogix platform, reducing dependency on the processors front port and optimizing processing time. Featuring CIPconnect technology, it supports both ControlNet and Ethernet/IP networks while providing advanced diagnostics via Ethernet. The module incorporates an onboard web server, local and remote diagnostics, and supports byte value-based protocols, making it ideal for versatile industrial applications. With a single-slot design and compatibility with the ControlLogix backplane, this module supports robust performance by handling up to 4096 ASCII character strings per port and operates efficiently within a broad temperature range.
