Module Type LED indicator Descriptions
CPU Error LED
There are five types of indicators 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 first for the CPU
module to keep on running. When the LED indicator is blinking slowly, indicating a
warning type of error codes, it does not require immediate action. Clear the
problems when the module is powered off.
Error type:
ON: A serious error occurs in the module.
Blinking fast (every 0.2 seconds): unstable power supply or hardware
Failure.
Blinking normally (every 0.5 second): system program errors or system
cannot run.
Warning type:
Blinking slowly (every 1 second and off for 3 seconds): a warning is
triggered, but the system can still run.
OFF: a warning is triggered, but the system can still run. You can modify the
rules and use DIADesigner-AX to show the warnings, instead of using
indicators to show the errors.
