20 MB user memory, embedded gigabit Ethernet and scalable capacity for demanding plantwide automation.
The Allen-Bradley 1756-L84E is a ControlLogix 5580 controller for high-performance machine, process and plantwide control. Rockwell Automation specifies 20 MB user memory, one embedded 1 Gb Ethernet port, a USB programming port and capacity for up to 250 EtherNet/IP devices. It supports up to 256 motion axes, Secure Digital nonvolatile memory and a four-character alphanumeric display. The controller installs in a ControlLogix chassis and coordinates local modules with distributed EtherNet/IP devices. Before replacement, compare the full catalog number, Series, firmware, Studio 5000 project, chassis, power supply, network design, communication modules and motion configuration.
Embedded Ethernet connects distributed I/O, drives, operator interfaces and peer controllers. USB supports temporary programming access; Secure Digital media provides the nonvolatile option.
Do not substitute GuardLogix safety, conformal-coated, extreme-environment or No Stored Energy variants without engineering review. Compare 1756-L84E, Series, firmware, Studio 5000, chassis, power supply, communication modules, SD card, Ethernet configuration and motion project.
