EtherNet/IP and CompactLogix Controller Features
The 1769-L35E uses CompactLogix backplane bus communication to coordinate controller operations and connected I/O modules. Furthermore, the Ethernet interface supports data exchange between the controller and EtherNet/IP networks for industrial control applications.
The controller supports I/O density scaling through a maximum configuration of 30 Compact I/O modules distributed across up to 3 I/O banks. In addition, the controller provides 1.5 MB user memory for application programs, controller tags, and execution data.
The integrated communication ports include an Ethernet port and an RS-232 serial port. Therefore, the controller can exchange data with network devices and serial equipment within compatible automation architectures.
Frequently Asked Questions

Q: What communication interfaces are available on the 1769-L35E? A: The controller provides 1 Ethernet port and 1 RS-232 serial port for network and serial communication.
Q: Can the 1769-L35E use a CompactFlash memory card? A: Yes. The controller supports the 1784-CF128 CompactFlash card for compatible storage functions.
Field Installation Guidelines
Install the 1769-L35E on a suitable DIN rail or panel mounting surface according to the controller installation requirements.
Maintain proper separation between communication wiring, power conductors, and high-voltage sources to reduce electrical interference. Connect cable shields according to the system grounding design and maintain correct grounding practices for the control cabinet.
Verify the 5 VDC and 24 VDC power supply loading before installation. The controller current requirements must remain within the available power supply capacity of the CompactLogix system.
Confirm Ethernet cable routing, connector condition, and network configuration before commissioning. Firmware compatibility should also be checked before replacing or upgrading controller hardware.
