AR 0713 (Error History Overwrite Bit) is turned ON or OFF by the user to control
overwriting of records in the Error History Area in the DM area. Turn ON AR 0713
to overwrite the oldest error record each time an error occurs after 10 have been
recorded. Turn OFF AR 0713 to store only the first 10 records that occur each
time after the history area is cleared.
AR 0714 (Error History Reset Bit) is turned ON and then OFF by the user to reset
the Error Record Pointer (DM 6000) and thus restart recording error records at
the beginning of the history area.
AR 0715 (Error History Enable Bit) is turned ON by the user to enable error histo-
ry storage and turned OFF to disable error history storage.
Refer to 3-6 DM Area for details on the Error History Area.
