Product Overview

The 1769-L31ER-NSE is a specialized CompactLogix 5370 L3 controller designed for environments where stored energy is restricted. The "NSE" (No-Stored Energy) model lacks internal capacitors or batteries for RTC or volatile memory retention, making it suitable for hazardous locations such as mining or explosive atmospheres. It delivers reliable processing power and high-speed communication within a compact, fanless design.

NSE Model Considerations

SD Card Dependency: User program must reside on SD card for retention.
Load on Power-Up: Configure controller to "Load Image on Power-up" to restore application logic automatically.
Clock Sync: RTC is not maintained; synchronize via NTP server when Ethernet is available.

Common Technical Questions

What happens to the system clock during power loss?
The clock resets to default. Use WallClockLog instructions or NTP synchronization to restore correct time.

Is integrated motion supported?
Yes, the L31ER-NSE supports integrated motion on EtherNet/IP within the node count and processing limits of the L31 series (16 nodes).
