Function
These words contain the time at which
the power was interrupted. The con-
tents are updated every time that the
power is interrupted. The data is
stored in BCD.
A512.00 to A512.07: Second (00 to
59)
A512.08 to A512.15: Minute (00 to 59)
A513.00 to A513.07: Hour (00 to 23)
A513.08 to A513.15: Day of month (01
to 31)
Note 1 These words are not cleared
at startup.
2 The data will be unstable if the
capacitor becomes
discharged.
3 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.
Contains the number of times that
power has been interrupted since the
power was first turned ON. The data is
stored in binary. To reset this value,
overwrite the current value with 0000.
Note The data will be unstable if the
capacitor becomes discharged.
The time that operation started as a
result of changing the operating mode
to RUN or MONITOR mode is stored
here in BCD.
A515.00 to A515.07: Seconds (00 to
59)
A515.08 to A515.15: Minutes (00 to
59)
A516.00 to A516.07: Hour (00 to 23)
A516.08 to A516.15: Day of month (01
to 31)
A517.00 to A517.07: Month (01 to 12)
A517.08 to A517.15: Year (00 to 99)
Note 1 The previous start time is
stored after turning ON the
power supply until operation is
started.
2 The data will be unstable if the
capacitor becomes
discharged.
3 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.
