Allen-Bradley 1769-L30ER-NSE CompactLogix 5370 ENet Processor
The Allen-Bradley 1769-L30ER-NSE, also cataloged as the 1769-L30ER-NSE Processor Module, operates as a dedicated hardware component for industrial process control and secure network execution within CompactLogix network platforms. Featuring a No Stored Energy (NSE) hardware architecture, the unit limits residual component energy to less than 200 uJ upon power down, preventing thermal arc generation across local circuit traces while processing data arrays over integrated physical channels.

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling
The central controller runs dual EtherNet/IP ports with embedded switching functionality, supporting Device Level Ring (DLR) topologies to maintain uninterrupted backplane bus communication velocity during media link failures. Local I/O density scaling allows a maximum connection of 8 expansion modules directly on the local chassis rail structure. Because the hardware uses an NSE physical profile, it omits the standard internal supercapacitor assembly; system layout designers must verify firmware flash compatibility and deploy external network time protocol synchronization loops to preserve real-time clock stability across the deterministic automation network.
Frequently Asked Questions
Q: Does this NSE variant support synchronized CIP motion axes over the EtherNet/IP ports?
A: No. The 1769-L30ER-NSE does not include integrated motion engine capabilities. Applications requiring multi-axis coordinated drive control must utilize motion-enabled processing units such as the 1769-L30ERM module.
Q: How does the lack of a supercapacitor affect the memory retention of the controller during power outages?
A: The unit relies on non-volatile flash memory architecture to store the application code when power is removed. However, the real-time clock registers will lose synchronization during extended dark periods unless linked to an external network master clock or an external hardware battery block.
Field Installation Guidelines
- Chassis Rail Interface and Locking: Position the processor onto an EN 50022 compliant 35 mm DIN rail or anchor it via the direct panel mount hole tabs. Slide the adjacent 1769 I/O module alongside the locking track and actuate the upper and lower bus levers to establish secure backplane bus trace continuity.
- Network Infrastructure and Separation: Insert Category 5e industrial-grade shielded cables into the RJ45 EtherNet/IP interfaces. Route all communications infrastructure separate from high-power AC conductors, variable frequency drive motor leads, and switching inductive loads to mitigate industrial noise coupling.
- Power Supply Constraints and Distance Limits: Verify that the primary system power supply remains within the specified module distance layout rules, ensuring the local 5 VDC rail does not drop below operating tolerances under a full 800 mA processor draw.
