There are five types of error indicator states for of the CPU module errors,
including LED indicator ON, OFF, blinking fast, blinking normally, and blinking
slowly. When the LED indicator is ON, blinking fast/normally, clear the problems

indicating a warning type of error codes, it does not require immediate action.
Clear the problems when the module is powered off.

Failure.
Blinking normally (every 0.5 second): system program errors or system

triggered, but the system can still run.
