DNP3 EVENTS CONFIGURATION MISMATCH

Allen-Bradley · MicroLogix 1400 Programmable Controllers

What does 002B mean?

The DNP3 event configuration (specifically status bit S:36/11 for 10K events) in the latest user project downloaded differs from the configuration present in the controller at power-up. This is a non-user fault requiring a power cycle for the new settings to take effect.

Common Causes

  • DNP3 10K events bit (S:36/11) was changed in the downloaded program but has not been applied due to a pending power cycle.
  • Discrepancy between stored power-up configuration and active downloaded configuration for DNP3 events.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Cycle power to the controller for the new DNP3 configuration to take effect and be properly loaded.

  2. 2

    Enter the Run mode after the power cycle is complete and the configuration is applied.
