5069-L310ER CompactLogix Controller | Allen-Bradley

Configured for high-speed logic execution in CompactLogix control networks, the Allen-Bradley 5069-L310ER (5069-L310ER Controller) provides direct physical/electrical execution of machine control sequences, supporting up to 8 local I/O modules and 24 Ethernet nodes.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The 5069-L310ER integrates into automation architectures via dual Ethernet ports, supporting Star, Linear, and Device Level Ring (DLR) topologies for deterministic communication. The controller manages task execution across 32 continuous tasks, with a capacity of up to 1000 programs per task. Firmware flash compatibility is managed via the integrated USB port (12 Mbps) or Ethernet interface (up to 1 Gbps). I/O density scaling is constrained by the 8-module local chassis limit; however, the processor's backplane bus communication velocity is engineered to maintain low-jitter data exchanges for time-critical motion and discrete control functions.

Frequently Asked Questions

Q: Can the controller perform hot-swapping of I/O modules while the system is under load?

A: The 5069 CompactLogix platform supports Removal and Insertion Under Power (RIUP) for local I/O modules. However, ensure the application code is designed to handle temporary loss of communication with the affected module during the removal interval to prevent safety-related faults.

Q: Are the Ethernet ports configured for a single IP address or distinct subnets?

A: The dual ports on the 5069-L310ER support both Linear and DLR topologies, typically sharing a single IP address for the controller. When configured in DLR mode, the ports automatically manage ring redundancy to ensure continuous connectivity.

Field Installation Guidelines

1. Mount the controller on a 35 mm DIN-rail, ensuring proper orientation for vertical airflow to facilitate heat dissipation.
2. Connect the 24 VDC power source to the removable terminal block; verify polarity before energizing to prevent internal circuit damage.
3. Utilize shielded Category 6 Ethernet cables for 1 Gbps network communication to minimize crosstalk and electromagnetic interference (EMI).
4. Route communication cables at least 150 mm away from high-voltage AC lines or motor power cabling to prevent induced noise on the Ethernet ports.
5. Terminate the shield of any shielded communication cabling to the cabinet's protective earth ground bus at the entry point of the enclosure.
6. Confirm module status via the front-panel LEDs; a steady green status indicator confirms that the controller has successfully initialized the firmware and is communicating with the local I/O bus.
