Allen-Bradley 1788-CNC A FlexLogic Communication Module

Allen-Bradley 1788-CNC A FlexLogic Communication Module is a ControlNet interface card for Rockwell Automation's FlexLogix platform, serving as the ControlNet communication module (daughter card) that links a FlexLogix controller to a ControlNet network for remote I/O and device communications. Identified as model 1788-CNC A, it ships with firmware version 1.008. In FlexLogix controller configurations, the 1788-CNC family (including CNCR variants) provides the ControlNet bridge for deterministic I/O updates and device messaging across the network. This module enables integration of ControlNet devices and remote I/O with a FlexLogix-based control system, making it suitable for industrial automation environments that rely on ControlNet connectivity. Common applications include connecting ControlNet I/O from distributed equipment to a FlexLogix controller to coordinate sequencing, safety interlocks, and real-time I/O operations within manufacturing and process control lines.
