A ControlLogix 5580 controller with 3 MB user memory, a USB programming port, an embedded 10/100/1000 Mbps EtherNet/IP port and a four-character display. It supports high-speed chassis control, EtherNet/IP I/O, integrated motion and multi-discipline Logix applications.
Integrated Network Access Changes the Chassis Layout
Embedded EtherNet/IP
The front Ethernet port handles I/O, communications and integrated motion without requiring a separate network module for the primary connection.
Programming and diagnostics
USB 2.0 Type B and the four-character display support commissioning and controller status work.
Execution structure
Supports 32 tasks, up to 1000 programs per task and Ladder, Structured Text, Function Block and Sequential Function Chart.
SERIES AND SYSTEM RELATIONSHIP
5580 Capacity Steps and Network Growth
L81E entry point
3 MB memory and up to 100 EtherNet/IP nodes suit compact to medium 5580 applications.
1756-L81E
The embedded 1 Gb port reduces chassis hardware and supports direct EtherNet/IP I/O and motion connections.
Higher 5580 models
L82E through L85E increase user memory and node capacity for broader applications while retaining the 5580 architecture.
GLOBAL INDUSTRIAL SUPPLY
People, Inspection and Dispatch in One Flow
Multilingual coordination supports controller matching and international orders.
Article number and visible condition are checked before dispatch preparation.
Large industrial stock supports fast coordination for current and long-unavailable parts.
Amikon's large stock is the core of our supply. More than 400,000 electronic products cover PLC, HMI, drives, servo, CNC, IPC and PG needs. Strategic purchasing, order tracking and a broad partner network help keep production moving.
How many EtherNet/IP nodes can 1756-L81E support? It supports up to 100 EtherNet/IP nodes with Logix Designer version 30 or later; version 29 supports 60 nodes.
Q2
Does 1756-L81E need a separate Ethernet module? Not for its primary EtherNet/IP connection. It includes one 10/100/1000 Mbps Ethernet port, although added modules may be used for segmentation or other networks.
Q3
Is 1756-L81E a safety controller? No. It is a standard ControlLogix 5580 controller. Safety applications require the appropriate GuardLogix catalog number and architecture.
Q4
What should be checked before replacing 1756-L81E? Confirm the complete catalog number, series, firmware revision, project version, IP settings, node count, motion use and chassis compatibility.
Q5
Which programming languages are supported by 1756-L81E? Ladder Diagram, Structured Text, Function Block Diagram and Sequential Function Chart are supported in the Logix environment.
