Supervision of ECC on memory (ECC error)
10.2.4
Error-correcting code memory (ECC memory) is verified at any time.
Error level
(i)
The error level has been set at level 1 (Serious error) in the automatic supervision. Checking
is carried out at any time. If an error is detected, the IED automatically restarts the operation.
The supervision function runs at the CPU module
when the error is solved.
Note: The CPU module is discussed in Chapter
1
and communication module: Signal processing
Error message
(ii)
When detecting an error, the error message will be shown on the LCD screen. LED will be lit
up.
