This happens when the 24 VDC power supply for the remote module is not sufficient. Check the power supply. If the
power supply is normal, remove the extension module from the CPU module and then check if the SCM remote module is
out of order. Error codes:

LED indicator
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 first in order to
run the CPU module. When the LED indicator is blinking slowly, indicating a
warning type of error codes, it does not require immediate action. Clear the
Error LED
problems when the module is powered off.
Error type:
ON: A serious error occurs in the module.
Solution
Check the parameter in HWCONFIG. Download the
parameter again.
Make sure the module is properly connected to the CPU
module and turn the modules on again.
Solution
Check whether the 24 V power supply to the module is
normal.
