The 1769-L35E/A is an Ethernet controller within the CompactLogix series. This module has been designed to meet the demands of modern automation environments, featuring a capacity of 1.5 MB for user memory. It allows for connections to a maximum of 30 I/O modules, arranged across up to three I/O banks, making it suitable for scalable applications.
1.5MB User Memory
Integrated EtherNet/IP Port
30-Module I/O Expansion
The unit incorporates one Ethernet port and an additional RS-232 serial port for versatile communication options. For memory expansion, the 1784-CF128 CompactFlash card is compatible with this controller, supporting further functionality.

Automotive Manufacturing
The controller coordinates complex assembly operations by managing high-speed discrete I/O and peer-to-peer data exchange over EtherNet/IP. It supports the synchronization of robotic cells and conveyor interlocks required for vehicle production.
Food & Beverage
Ideal for high-speed bottling and packaging lines that require precise timing and recipe management within a compact footprint. The integrated Ethernet port allows for seamless connection to HMI and enterprise-level data collection systems.
Water Treatment
Supports distributed control of pumping stations and filtration systems by leveraging the 30-module I/O expansion capability. It provides reliable processing for chemical dosing logic and remote monitoring via standard networking protocols.
Material Handling
Manages automated storage and retrieval systems (ASRS) and extensive conveyor networks in large distribution centers. The processor handles the frequent communication traffic necessary for carrier tracking and high-speed sorting control.
Pharmaceutical Processing
Ensures high-integrity control for batch processing and environment monitoring in regulated manufacturing environments. The 1.5MB memory capacity accommodates extensive data logging and complex control algorithms needed for regulatory compliance.
Oil & Gas
Utilized in midstream applications for monitoring pipeline pressure and flow rates across distributed terminal stations. Its robust design and support for serial and Ethernet communication enable reliable data integration from remote field instrumentation.
The 1769-L35E/A controller must be installed within four modules of a 1769 power supply to ensure proper backplane power distribution, as dictated by its power supply distance rating of 4. To maintain the contents of the volatile memory and the real-time clock during power loss, a 1769-BA lithium battery must be properly connected and replaced when the BATT LED indicates a low-voltage condition.
The controller requires a solid connection to a functional earth ground using 14 AWG copper wire to ensure electromagnetic compatibility and protection against electrical noise in industrial environments. For non-volatile storage of user programs and data, a 1784-CF128 CompactFlash card can be utilized, but it must be inserted or removed only while the controller is powered down to prevent data corruption or hardware damage.
Operators should monitor the front-panel status indicators, specifically the OK and NS LEDs, to verify internal hardware health and EtherNet/IP network connectivity during the power-up sequence and continuous operation.
What is the user memory capacity available for the 1769-L35E/A controller?
The 1769-L35E/A controller is equipped with 1.5 Mbytes of available user memory for storing program logic and data tags.
What communication ports are built-in to the 1769-L35E/A processor?
The 1769-L35E/A features one built-in EtherNet/IP port and one RS-232 serial port (DF1 or ASCII protocols supported).
How many 1769 Compact I/O modules can be supported by a 1769-L35E/A system?
The 1769-L35E/A controller can support a maximum of 30 I/O modules across up to 3 I/O banks.
What is the power supply distance rating for the 1769-L35E/A controller?
The 1769-L35E/A has a power supply distance rating of 4, meaning it must be located within 4 slots of the power supply.
Does the 1769-L35E/A require a battery for memory retention?
Yes, the 1769-L35E/A uses a 1769-BA lithium battery to provide back-up power for the volatile memory when system power is removed.
