002B
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
Cycle power to the controller for the new DNP3 configuration to take effect and be properly loaded.
- 2
Enter the Run mode after the power cycle is complete and the configuration is applied.
