Features:
- Built-in ControlNet Communication Port for High-Speed Deterministic Networking
- Dual Protocol Support via Integrated RS-232 Serial Interface (System or User)
- Compact 1769 Backplane Integration Powered Directly at 650 mA (5V DC) and 40 mA (24V DC)
The Allen Bradley 1769-L32C operates as the primary Programmable Automation Controller within a CompactLogix system, delivering central processing power and integrated network connectivity. It draws power directly through the 1769 backplane bus—requiring 650 mA at 5V DC and 40 mA at 24V DC—to maintain continuous execution of control logic and communication services. Equipped with a built-in ControlNet port and an RS-232 serial port (supporting both system and user protocols), the 1769-L32C manages real-time data flow between localized processing tasks and high-speed distributed networking without requiring additional communication expansion cards.
The 1769-L32C executes essential control logic common to the entire I/O system, making it the critical intelligence node that directly dictates the normal operation of all connected field devices. Exactly one 1769-L32C controller is permitted per CompactLogix system, and it must always be installed in Slot 0 (the leftmost position of the local bank). To guarantee proper backplane signal integrity and operating voltage, the 1769-L32C must be positioned within four module slots of the system power supply, while standard I/O modules can reside up to eight slots away.
For Distributed I/O applications, the 1769-L32C coordinates remote I/O banks across a ControlNet network. In the programming software's I/O Configuration folder, engineers establish network communication by adding ControlNet adapters and remote I/O modules directly beneath the 1769-L32C. Using this hierarchical structure, the system organizes modules into a parent/child tree and branch configuration to systematically monitor device health, update I/O tags, and report communication events.
The 1769-L32C Allen Bradley CompactLogix Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
