More Information

Overview Manuals Catalog Boundary Connection Scope Project Evidence Product Applications

Features:

  • Non-motion controller: the ER suffix separates this catalog from motion-enabled L36 variants
  • 3 MB project boundary: the published application capacity anchors selection
  • Defined communication scope: dual EtherNet/IP, USB, and controller connections are documented
1769-L36ER should first be recognized by its exact suffix, because visually related L36 catalogs carry different controller roles.

The model belongs to the CompactLogix 5370 L3 architecture and is intended for general control projects within its confirmed memory and communication limits.

Where public exact-model evidence is unavailable, the page must remain deliberately narrower instead of borrowing motion, logistics, or revision details from adjacent controllers.

Apter Power can support exact-model document review, quotation coordination, and procurement checks for 1769-L36ER.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Exact suffix: preserve 1769-L36ER in purchase, project, nameplate, and service records.
  • Controller role: use the catalog only for its documented non-motion CompactLogix L3 function.
  • Variant limit: do not transfer ERM or ERMS motion capability to the ER controller.
  • Evidence rule: leave unconfirmed revision, logistics, and replacement claims outside the page.
  • Controller connections: keep the complete I/O, produced-data, message, and client design within 256 connections.
  • Ethernet paths: document both ports, addressing, topology, and connected-device profiles.
  • USB access: retain a controlled local programming and recovery procedure.
  • Peak test: validate connection recovery and communication load with the approved project.
  • Memory report: compare the compiled application and growth reserve with the confirmed 3 MB capacity.
  • Firmware record: preserve the controller revision and supported Studio 5000 environment.
  • Device map: archive remote I/O, drives, HMIs, messages, and produced or consumed data paths.
  • Recovery proof: bench-load the approved project and verify representative communication before installation.
  • General Logix control: execute a verified non-motion application within the 3 MB memory boundary.
  • EtherNet/IP automation: coordinate supported I/O and other networked devices within the connection scope.
  • Dual-port controller systems: use the documented CompactLogix 5370 Ethernet arrangement.
  • Compact I/O architectures: maintain an approved L3 controller project with its installed local I/O design.
Description
1769-L36ER is identified in Rockwell Automation selection data as a 3 MB, non-motion CompactLogix 5370 L3 controller. Its role is general Logix control through dual EtherNet/IP connectivity rather than the Integrated Motion function associated with neighboring ERM and ERMS catalogs.

A published allocation of controller connections gives 1769-L36ER a defined communication boundary for I/O, produced or consumed data, messages, and supervisory access. USB supports local programming and recovery work within the documented controller environment.

Because 1769-L36ER is easily confused with longer L36 suffixes, exact-catalog control is central to procurement. Only facts tied to the ER catalog should be used; motion capability, logistics, and revision data must remain unclaimed unless Rockwell Automation documents them for this exact model.

Technical notes
The main ordering risk for 1769-L36ER is loss of the final non-motion suffix when it is compared with L36ERM or L36ERMS catalogs. Match the full nameplate, 3 MB project role, and connection record; reject any quotation or substitute that does not preserve the exact ER identity.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How should a buyer distinguish 1769-L36ER from L36ERM and L36ERMS quotations?
Require the complete ER suffix on the nameplate and quotation, then confirm that the application is non-motion and does not depend on functions documented only for ERM or ERMS catalogs.
What should be investigated when 1769-L36ER reaches a communication limit unexpectedly?
Inventory I/O connections, produced and consumed tags, messages, programming clients, HMIs, and device profiles, then compare their combined use with the published controller allocation.
How can an engineer determine whether a project fits 1769-L36ER?
Use the compiled memory report, controller-connection summary, Ethernet architecture, local I/O design, firmware requirement, and maintenance margin rather than the source-file size alone.
What should incoming inspection cover before 1769-L36ER is installed?
Match the exact catalog label, inspect USB and Ethernet ports, record firmware access and physical condition, and require traceability plus a controlled project-load test.
Can motion capability be assumed for 1769-L36ER because the machine uses EtherNet/IP drives?
No. EtherNet/IP connectivity does not establish Integrated Motion support; stop the selection unless the exact controller is officially documented for the required axis functions.
Which bench test is appropriate for a sourced 1769-L36ER?
Load the approved firmware and project, verify USB access, exercise both Ethernet paths with representative devices, review diagnostics, and compare communication behavior with the saved machine baseline.
