5069-L310ER | Allen-Bradley CompactLogix 5380 1MB EtherNet/IP Controller

Module Overview

The 5069-L310ER is a high-performance member of the CompactLogix 5380 controller family, engineered to provide increased throughput and modern integrated security for small to mid-sized applications. This controller features dual 1Gbps Ethernet ports, allowing for high-speed I/O control and plant-wide data exchange. While it supports up to 256 non-motion axes for localized logic, the 5069-L310ER is optimized for discrete control and data processing with a capacity of 24 EtherNet/IP nodes. It utilizes the high-speed 5069 backplane, which offers significantly faster I/O response times compared to legacy 1769 architectures.

Detailed Engineering Specifications

Advanced Performance and Power Distribution

The 5380 series introduces a unique power architecture that separates system logic power from field-side power. To operate the 5069-L310ER, you must provide two distinct power connections to the removable terminal block (RTB):

• MOD Power: Powers the internal controller logic and the 5069 backplane bus.

• SA Power: Provides the sensor/actuator power that is distributed to the local I/O modules installed in the rack.

This isolation ensures that field-side electrical noise or short circuits do not affect the stability of the main controller's processing engine.

Security and Data Integrity

The 5069-L310ER includes advanced security features such as digitally signed firmware to prevent unauthorized code from running on the hardware. It also supports the 9509-CMSDCD4 CodeMeter card for applications requiring hardware-based license protection and intellectual property security. The Gigabit Ethernet capability ensures that even with heavy security encryption and high-density I/O traffic, the controller maintains a consistent and predictable scan time.

Technical FAQ

Can I use the 5069-L310ER for motion control applications?

The 5069-L310ER is a standard controller with "0 Motion Axes" support. If your application requires synchronized servo control over EtherNet/IP, you would need the "M" version of the controller, such as the 5069-L310ERM.

Is this controller compatible with legacy 1769 Compact I/O modules?

No. The 5380 controllers utilize the 5069 high-performance backplane. You cannot physically or electrically connect 1769 modules to this controller. However, you can control 1769 I/O as remote nodes over an EtherNet/IP network.

What is the benefit of the Gigabit Ethernet ports?

The 1Gbps ports provide significantly higher bandwidth for data-intensive tasks such as high-speed I/O, messaging between controllers, and HMI communication, reducing network latency and improving overall system responsiveness.
