EII ERROR
Allen-Bradley · MicroLogix 1400 Programmable Controllers
What does 002E mean?
An error occurred in the External Interrupt Input (EII) configuration. This is a recoverable fault, meaning the controller can potentially continue operation if the error is addressed, but the EII function may not work as intended.
Common Causes
- Invalid parameters or settings within the EII configuration (e.g., undefined interrupt source, incorrect edge detection).
- Conflicting EII routines or input assignments that interfere with each other.
- Hardware issue related to the external interrupt input circuitry.
