6.7 Self-diagnostics Function
6.7.2 Cancel the error
POINT
1. When the error code for the error to be canceled is stored in SD50 and the
error is canceled, the bottom 1-digit code number is ignored.
(Example)
If error code 2100 or 2106 occurred, when error code 2100 is canceled, error
code 2106 is canceled too.
If error code 2100 or 2125 occurred, even when error code 2100 is canceled,
error code 2125 is not canceled.
2. If an error occurred due to a cause other than the CPU module, even if the
error is canceled using a special relay (SM50) and special register (SD50),
the cause of the error cannot be eliminated.
(Example)
For "INTELLIGENT FUNCTION MODULE DOWN", because this error
occurred in the base unit, intelligent module, or the like, even if the error is
canceled using a special relay (SM50) and special register (SD50), the cause
of the error cannot be eliminated.
Refer to the error code list in the QSCPU User's Manual (Hardware Design,
Maintenance and Inspection) and eliminate the cause of the error.
