1769-L30ER-NSE CompactLogix 5370 L3 No-Cap Controller

1769-L30ER-NSE is the no-supercapacitor version of the CompactLogix 5370 L3 1 MB controller, so it performs Logix control and EtherNet/IP communication without the RTC supercapacitor configuration of 1769-L30ER. The project, controller series and clock-retention requirements must therefore be checked before substitution.

1769-L30ER-NSE controls the machine with 1 MB memory, dual DLR Ethernet and up to eight local I/O modules, while its NSE hardware omits the real-time-clock supercapacitor. Maintenance must confirm timekeeping expectations, firmware and the exact NSE catalog suffix rather than treating a standard L30ER as automatically equivalent.

1769-L30ER-NSE operates as the CompactLogix CPU for a 1769 Compact I/O assembly and supports up to eight local expansion modules, representing up to 128 local I/O points in the documented configuration. The installed power supply, module current budget and physical module order must fit that limit.

1769-L30ER-NSE uses two embedded EtherNet/IP ports to provide one switched controller interface with linear and DLR wiring capability. The configuration supports up to 16 EtherNet/IP nodes, so the ports must be engineered as one controller network rather than two isolated networks.

1769-L30ER-NSE is a non-motion CompactLogix 5370 L3 controller that provides logic, local Compact I/O expansion and EtherNet/IP communication with 1 MB memory. It does not provide integrated CIP Motion axes; motion applications require an ERM catalog number and compatible drives, firmware and project design.

1769-L30ER-NSE must be verified as the exact no-cap controller entity before it restores logic, I/O and Ethernet communication. Confirm the 1769 power supply, eight-module layout, 16-node network, DLR cabling, 1 MB project size, SD-card image, series, firmware, Studio 5000 version and RTC requirements.
