3122 Time interval used to record time data in operation history
[Data type] Word
[Unit of data] Minutes
[Valid data range] 0 to 1439
Time data is recorded in operation history at set intervals. When 0 is
specified in this parameter, 10 minutes is assumed as the default.
However, note that time data is not recorded if there is no data to be
recorded at the specified time.
NOTE
1 While the operation history screen is displayed, history data
is not recorded.
2 When the duration of the on/off state of an input signal is 16
msec or shorter, that state is not recorded in the history. In
addition, note that some signals are not recorded in the
history.
3 Once the memory area becomes full, the oldest data is
deleted to allow new data to be recorded. The memory area
can store information corresponding to approximately 8000
key strokes.
4 Recorded history data is held in memory even after the
power is turned off. Note, however, that the history data is
erased by performing an entire–memory clear operation.
5 For the operation history function, sampling is disabled
when bit 7 (OHS) of parameter No. 3106 is set to 1.
6 Be careful to set the date and time correctly.
When the time is recorded at regular intervals, but no data
is recorded within a defined period, the time for that period
is not recorded.
