Bit
Turn ON this bit to preserve the status
of bits that have been force-set or
force-reset when shifting from PRO-
GRAM to MONITOR mode or vice
versa. Always use this bit together with
the IOM Hold Bit (A500.12), i.e., turn
them ON at the same time.

Area itself (A100 to A199) are
not cleared.

to 0 after the Error Log Pointer
is reset.

15 Output OFF Bit Turn this bit ON to turn OFF all outputs
from the CPU Unit, CP-series Expan-
sion Units, and CP-series Expansion
I/O Units. The INH indicator on the
front of the CPU Unit will light while
this bit is ON.
Note This bit is cleared when the
power supply is turned OFF.

− Startup Time These words contain the time at which
the power was turned ON. The con-
tents are updated every time that the
power is turned ON. The data is stored
in BCD.
A510.00 to A510.07: Second (00 to
59)
A510.08 to A510.15: Minute (00 to 59)
A511.00 to A511.07: Hour (00 to 23)
A511.08 to A511.15: Day of month (01
to 31)
Note 1 The data will be unstable if the
capacitor becomes
discharged.
2 In an E-type CPU Unit, or if
the clock data is not set for an
N/NA-type CPU Unit, the data
will be for 1:01.01 on Sunday
January 1, 2001.
