Allen-Bradley 5069-L320ER CompactLogix 5380 Controller

Overview

The Allen-Bradley 5069-L320ER is a CompactLogix 5380 programmable automation controller from Rockwell Automation, sized for small and medium machines, skids and process units. It provides 2 MB of user memory, supports up to 16 local Compact 5000 I/O modules and up to 40 EtherNet/IP nodes, and uses the same Logix 5000 control engine and Studio 5000 Logix Designer software as larger ControlLogix systems. It is a standard (non-motion) controller: the ER suffix indicates two embedded EtherNet/IP ports without Integrated Motion on EtherNet/IP, which keeps the controller focused on discrete, process and network control rather than servo axis coordination.

Seven Star LLC supplies the Allen-Bradley 5069-L320ER to system integrators, OEM skid builders, utilities and oil and gas operators in Oman and the GCC, with engineering support in Muscat. It is often selected when an SLC 500 or MicroLogix panel is being modernised and the owner wants a Logix-based controller that matches the rest of the plant without paying for motion or memory that the application will never use.

Operating Principle

The controller executes a tag-based Logix application organised into tasks, programs and routines. The Allen-Bradley 5069-L320ER supports up to 32 tasks (continuous, periodic and event) with up to 1000 programs per task, and routines can be written in Ladder Diagram, Structured Text, Function Block Diagram or Sequential Function Chart. Local Compact 5000 I/O modules mounted to the right of the Allen-Bradley 5069-L320ER are scanned over the backplane, while remote I/O, drives, HMIs and other controllers are reached over EtherNet/IP; Rockwell rates the Ethernet interface for up to 128,000 Class 0/1 I/O packets per second without CIP Security.

The two Ethernet ports of the Allen-Bradley 5069-L320ER run at 10 Mbps, 100 Mbps or 1 Gbps, full duplex. In Dual-IP mode each port has its own IP address, so the controller can sit on a device-level network and a separate plant or enterprise network at the same time. In Linear/DLR mode the ports share one address and act as an embedded switch for linear or Device Level Ring topologies, so a single cable break does not stop communication. CIP Security, ODVA conformance tested, adds device authentication, integrity and optional confidentiality to the connections.

Engineering Design of the Allen-Bradley 5069-L320ER

The Allen-Bradley 5069-L320ER mounts horizontally on a 35 × 7.5 mm EN 50022 DIN rail and measures about 144 × 98 × 137 mm, weighing 0.768 kg. The front carries status indicators, the two RJ45 Ethernet ports, a USB 2.0 Type B port for programming, configuration and firmware updates, and an SD card slot. The controller ships with a 1784-SD2 (2 GB) card and also accepts 1784-SD1, 1784-SDHC8, 1784-SDHC32 and 9509-CMSDCD4 CodeMeter cards for nonvolatile storage of the project and firmware.

Power is wired through two removable terminal blocks ordered separately as a 5069-RTB64-SCREW or 5069-RTB64-SPRING kit. MOD Power (18–32 V DC, 450 mA maximum) supplies the controller and module electronics, and SA Power (0–32 V DC or 0–240 V AC) is passed along to field-side circuits of the I/O modules, with up to 10 A on each bus. Maximum power dissipation is 8.5 W. The open-style module is installed in a suitable enclosure and is rated for 0 to 60 °C operation, 5 g vibration and 30 g operating shock.

Key Features

The Allen-Bradley 5069-L320ER offers a balanced feature set for mid-sized control systems:

• 2 MB user memory with up to 16 local Compact 5000 I/O modules and 40 EtherNet/IP nodes.
• Two embedded 1 Gbps EtherNet/IP ports supporting Dual-IP, linear, star and Device Level Ring topologies.
• CIP Security for authenticated and encrypted connections to HMIs, engineering stations and other Logix controllers.
• Up to 32 tasks and 1000 programs per task, programmed in LD, ST, FBD and SFC with Studio 5000 Logix Designer.
• SD card storage (2 GB card included) for project backup and automatic restore after controller replacement.
• USB 2.0 port for local programming, configuration, firmware updates and online edits.
• Hazardous location approvals for Class I Division 2 and ATEX/IECEx Zone 2 (Ex ec IIC T4 Gc), plus CE, UKCA, RCM, KC and CCC.
• Program portability across the Logix family, so code written for this controller can move to a larger CompactLogix or ControlLogix unit.

Industrial Applications

Across Oman, the Allen-Bradley 5069-L320ER is used on water and wastewater pumping stations, reservoir and well-field telemetry panels, chemical dosing skids, filtration units and desalination pretreatment trains. In upstream and midstream oil and gas, it controls packaged equipment such as chemical injection, produced water treatment, fuel gas conditioning and air compressor skids, where the Zone 2 approval and 60 °C rating suit field shelters and local equipment rooms. District cooling plants, utility substations and building services also use it for chiller sequencing and pump control.

In factories in Sohar, Salalah, Rusayl and Duqm, the Allen-Bradley 5069-L320ER runs packaging lines, mixers, batching systems, conveyors and process utilities, often together with PowerFlex drives and PanelView HMIs on one EtherNet/IP network. Where a project needs coordinated servo axes, a CompactLogix 5380 controller with the M suffix is the better fit; where only discrete, analog and networked devices are involved, this ER model avoids unnecessary cost. Seven Star LLC supplies the controller with RTB kits, SD cards and matching Compact 5000 I/O for projects across the GCC.
