To cancel the errors, follow the steps shown below.
1) Read the special register SD81 with GX Developer and confirm the cause of
the continuation error that currently occurs in the CPU module.
2) Eliminate the cause of the error.
3) Store the error code to be canceled in the special register SD50.
4) Energize the special relay SM50 (OFF ON).
5) Read the special register SD81 with GX Developer again and confirm that the
bit corresponding to the canceled continuation error is turned OFF.
6) Turn the special relay SM50 OFF.
After the CPU module is reset by the canceling of the error, the special relays, special
registers, and LEDs associated with the error are returned to the status under which
the error occurred.
If the same error occurs again after the cancellation of the error, it will be registered
again in the operation/error history.

When multiple enunciators(F) detected are canceled, the first one with No. F only is

If the canceling of errors is performed when multiple continuation errors are occurring,
