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 start-up,
but it is cleared when the Memory
Corruption Detected Flag (A39511)
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.
A51500 to A51507: Seconds (00 to
59)
A51508 to A51515: Minutes (00 to
59)
A51600 to A51607: Hour (00 to 23)
A51608 to A51615: Day of month (01
to 31)
A51700 to A51707: Month (01 to 12)
A51708 to A51715: 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.
A51800 to A51807: Seconds (00 to
59)
A51808 to A51815: Minutes (01 to
59)
A51900 to A51907: Hour (00 to 23)
A51908 to A51915: Day of month (01
to 31)
A52000 to A52007: Month (01 to 12)
A52008 to A52015: Year (00 to 99)
Note: If an error occurs in operation,
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 start-up,
but it is cleared to 0000 when the
Memory Corruption Detected Flag
(A39511) goes ON.)
Turn this bit ON to restart the RS-
232C port. (Do not use this bit when
the port is operating in Peripheral
Bus Mode.)
This bit is turned OFF automatically
when the restart processing is com-
pleted.
Turn this bit ON to restart the periph-
eral port.
This bit is turned OFF automatically
