Function
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.
(This word is not cleared at startup,
but it is cleared when the Memory
Corruption Detected Flag (A395.11)
goes ON.)
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

A517.00 to A517.07: Month (01 to
12)
A517.08 to A517.15: Year (00 to 99)
Note The previous start time is
stored after turning ON the
power supply until operation
is started.
The time that operation stopped as a
result of changing the operating
mode to PROGRAM mode is stored
here in BCD.
A518.00 to A518.07: Seconds (00 to
59)
A518.08 to A518.15: Minutes (01 to
59)
A519.00 to A519.07: Hour (00 to 23)

12)
A520.08 to A520.15: Year (00 to 99)
Note If an error occurs in opera-
tion, the time of the error will
be stored. If the operating
mode is then changed to
PROGRAM mode, the time
that PROGRAM mode was
entered will be stored.
Contains the total time that the PLC
has been ON in 10-hour units. The
data is stored in binary and it is
updated every 10 hours. To reset
this value, overwrite the current
value with 0000.
(This word is not cleared at startup,
but it is cleared to 0000 when the
Memory Corruption Detected Flag
