detections
The value of this register increments by one and stored as a BIN code, each
time input voltage drops to 85% (AC power)/65% (DC power) or less of the
nominal value while the CPU module is carrying out an operation. A counting
cycle from 0 to 65535 to 0 is repeated.

Detected
annunciator
number
• Numbers of activated annunciators are sequentially registered into SD64
to SD79, each time an annunciator (F) is turned on by the SET F
instruction.
• Number of the annunciator deactivated by the RST F instruction is
removed from register areas SD64 to SD79, and the numbers of
annunciators which were lined up behind the removed one move forward
one by one. When the number of detected annunciators has already
reached 16, the number of a newly detected annunciator is not stored into
SD64 to SD79.
For details on the annunciator, refer to the annunciator (F) ( Page 334
