- 67 12.4 Clearing an error
POINT
1. When the error is canceled with the error code to be canceled stored in the
SD50, the lower one digit of the code is neglected.
(Example)
If error codes 2100 and 2106 occur, and error code 2100 to cancel error
code 2106.
If error codes 2100 and 2125 occur, error code 2125 is not canceled even if
error code 2100 is canceled.
2. Errors developed due to trouble in other than the CPU module are not
canceled even if the special relay (SM50) and special register (SD50) are
used to cancel the error.
(Example)
Since "INTELLIGENT FUNCTION MODULE DOWN" is the error that
occurred in the base unit, intelligent function module, etc. the error cause
cannot be removed even if the error is canceled by the special relay (SM50)
and special register (SD50).
Refer to the error code list and remove the error cause.
