Communication Adapter Module | Allen-Bradley 1788-CNCR
The 1788-CNCR is a ControlNet communication module designed to interface Allen-Bradley FlexLogix and DriveLogix controllers with redundant ControlNet coaxial media networks. Operating at a high-speed data transfer rate of 5 Mbps, the unit provides reliable determinism for time-critical industrial control networks. It supports up to 32 logical connections, enabling real-time I/O control, peer-to-peer messaging, and program maintenance across complex automation systems.
Media Redundancy and Network Architecture
Equipped with dual coaxial BNC connectors, the 1788-CNCR supports redundant network cabling configurations to ensure continuous operational uptime. If a break or fault occurs on the primary coaxial link, data transmission automatically switches over to the secondary line without interrupting process operations or faulting the connected controller. This deterministic architecture makes it suitable for critical machine control and distributed process environments.
System Integration and Compatibility
This module connects directly to the system backbone of FlexLogix (1794-L3x) controllers and compatible DriveLogix processor platforms, allowing seamless integration of local and remote ControlNet drops. Maintenance personnel and system integrators can configure network parameters, target nodes, and connection schedules using RSNetWorx for ControlNet software.

Frequently Asked Questions
Q: What is the main difference between the 1788-CNC and the 1788-CNCR? A: The 1788-CNCR features dual BNC connectors specifically for redundant ControlNet coaxial media cabling, whereas non-R variants support single media channels without redundancy.
Q: How is network scheduling configured for the 1788-CNCR? A: Network schedules, Scheduled Bandwidth (NUT), and Network Update Times must be configured and saved into the network memory via RSNetWorx for ControlNet software.
