Features:
- Central Controller for CompactLogix Systems and Distributed I/O Networks
- Integrated Dual ControlNet Ports Supporting Redundant Media Communication
- Direct Support for 1769 Backplane Bus and Serial Interface Protocols
The 1769-L35CR Allen-Bradley CompactLogix Controller serves as the central processing unit within a 1769 CompactLogix system, delivering high-performance control and real-time data exchange for mid-sized industrial automation applications. It incorporates 1.5 MB of embedded user memory and features built-in dual ControlNet channels (Channel A and Channel B) to maintain continuous communication with remote I/O chassis and network nodes over redundant media. In addition to ControlNet connectivity, the 1769-L35CR includes an integrated RS-232 serial port supporting system or user protocols (such as DF1 or ASCII) for flexible connection to legacy devices, programming terminals, and operator interfaces.
The 1769-L35CR handles time-critical control functions across the system backplane and represents the core control engine for the entire 1769 system architecture. In a standard CompactLogix system, exactly one controller is permitted per system. The 1769-L35CR is mechanically designed to occupy the leftmost position of the local bank, functioning exclusively in Slot 0.
For High-Availability ControlNet applications, the 1769-L35CR enables continuous network monitoring across its redundant ControlNet media channels. In addition to standard single-cable ControlNet operation, the redundant configuration automatically manages network traffic across both physical links. The 1769-L35CR constantly monitors the integrity of the network connections on Channel A and Channel B. If the system detects a cable break or signal degradation on the primary ControlNet link, it seamlessly transitions media communication to the secondary channel without disrupting I/O scanning or processor execution, maintaining uninterrupted determinism across distributed I/O racks.
The 1769-L35CR Allen Bradley CompactLogix Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
