• When F goes ON due to or , the F numbers
which go progressively ON from SD64 through SD79 are
registered.
• The F numbers turned OFF by are deleted from
SD64 - SD79, and the F numbers stored after the deleted F
numbers are shifted to the preceding registers.
After 16 annunciators have been detected, detection of the
17th will not be stored from SD64 through SD79.

Cause of error
• When a continuation error occurs, the corresponding bits are
all set to ON.
• Canceling the error, starting up the safety PLC power or
canceling the safety CPU module reset after eliminating the
cause of the error makes the bits go OFF.
