EtherNet/IP and ControlLogix 5580 Architecture
The 1756-L85EK controller integrates the ControlLogix 5580 platform communication layer with embedded Ethernet interfaces supporting deterministic EtherNet/IP network operation. The dual Ethernet ports provide 10/100/1000 Mbps communication capability for controller-to-controller, I/O, and device-level data exchange.
The controller supports I/O density scaling up to 128,000 digital I/O points and 4,000 analog I/O points. Firmware flash compatibility and application configuration are managed through the ControlLogix engineering environment using Studio 5000 Logix Designer.
The K suffix specifies conformal coating applied to the controller assembly. The coating layer provides additional protection against moisture, dust, and corrosive environmental exposure during operation.

Field Installation Guidelines
Install the controller in an approved ControlLogix chassis with compatible power and backplane connections. Confirm module seating, chassis grounding, and controller firmware compatibility before system startup.
Maintain separation between Ethernet communication wiring and high-voltage power conductors to reduce electrical interference. Apply industrial grounding practices for cable shields and verify network topology requirements before connecting EtherNet/IP devices.
Avoid damaging the conformal coating surface during handling or installation. Inspect connectors and enclosure conditions before commissioning the controller in environments with moisture or corrosive contaminants.
