Allen-Bradley 5069-L380ERM – EtherNet/IP Motion Controller | CompactLogix 5380 Platform
Engineering Background: The CompactLogix 5380 series represents Rockwell Automation’s mid-range control architecture, engineered for applications demanding tightly synchronized motion, high-speed I/O, and deterministic EtherNet/IP communication. The 5069-L380ERM is the motion-optimized variant within this family, purpose-built for multi-axis coordinated control in discrete manufacturing, packaging, and material handling environments.
Product Positioning: Targeting procurement engineers and system integrators who require a verified, in-stock Allen-Bradley motion controller with dual Ethernet ports, 3MB user memory, and native CIP Motion support — without the lead times of new OEM orders. The 5069-L380ERM bridges the gap between compact form factor and enterprise-grade motion performance.

- Native CIP Motion: Eliminates the need for a separate motion controller; axis configuration, tuning, and diagnostics all reside within Studio 5000
- Compact 5069 Backplane: Higher bandwidth backplane vs. legacy 1769 CompactLogix — supports faster I/O update rates and more deterministic scan times
- Scalable Architecture: Seamlessly upgrades within the 5380 family (L306ERM → L380ERM → L3100ERM) without rewiring or re-engineering the panel
- Integrated Safety Ready: Compatible with 5069 GuardLogix safety modules for SIL 2 / PLe applications on the same backplane
- ControlLogix Ecosystem Compatibility: Shares tag-based programming model, Add-On Instructions (AOIs), and UDTs with ControlLogix — reducing engineering ramp-up time
System Architecture & Signal Flow
The 5069-L380ERM operates as the central execution engine within a 5069 Compact I/O system. The controller communicates with servo drives (e.g., Kinetix 5500, 5700) via CIP Motion over EtherNet/IP, delivering position, velocity, and torque commands at configurable coarse update periods (as low as 250 µs). Local I/O modules connect via the high-speed 5069 backplane, while remote I/O and HMI devices communicate over the dual Ethernet ports. The DLR capability allows a single broken cable segment to be tolerated without loss of communication — a key reliability feature for ring-topology installations.
Typical signal flow: Studio 5000 Engineering Workstation → EtherNet/IP Network → 5069-L380ERM Controller → 5069 Backplane (local I/O) + EtherNet/IP (Kinetix drives, remote I/O, PanelView HMI)
Sourcing & Quality Verification

- Step 2: Submit RFQ or place order directly — volume pricing available for 3+ units
- Step 3: Receive order confirmation with estimated ship date (typically 1–3 business days for in-stock units)
- Step 4: Shipment with tracking; DDP/DAP Incoterms available for international orders
- Step 5: Post-delivery technical support via email or phone for installation and commissioning queries
Technical FAQ
- Q: What is the difference between 5069-L380ERM and 5069-L380ER?
- The ERM suffix denotes the EtherNet/IP Motion variant, which includes native CIP Motion support for coordinated axis control. The ER variant supports standard EtherNet/IP I/O but does not include motion instruction sets.
- Q: Which Studio 5000 version is required?
- Studio 5000 Logix Designer v31.011 or later is required. Rockwell Automation recommends using the latest available version for full feature support and security patches.
- Q: Can this controller replace a 1769-L36ERM CompactLogix?
- Yes, with a migration project in Studio 5000. The 5069 platform is not a drop-in replacement (different backplane, power supply, and I/O modules), but the tag-based program logic can be imported with minimal modification using the Migration Toolkit.
- Q: Is the 5069-L380ERM compatible with Kinetix 5700 drives?
- Yes. The Kinetix 5700 is the recommended servo drive family for this controller, supporting CIP Motion over EtherNet/IP with shared DC bus architecture for energy efficiency.
- Q: What is the maximum number of motion axes?
- Up to 31 coordinated motion axes are supported, configurable as servo, virtual, or consumed axes within the Logix Designer axis configuration.
