• Data Count (Stop Condition)
Logging stops when a specified number of data points is logged.
Logging interval = scan interval x recording rate x specified data count.
• Fixed Time (Start/Stop Conditions)
A time within a 24-hour period (HH:MM:SS.SSS) can be specified. The times of the
acquired data are scanned, and logging starts or stops when the time of the data
retrieved from the monitor server is equal to or greater than the specified time.
When logging, logging starts when the time of the data retrieved from the monitor
server is equal to or greater than the specified time. Logging stops when the time of
the data retrieved from the monitor server is equal to or less than the specified time (the
specified stop time is not exceeded).

Logging starts at affixed time Logging stops at a fixed time
For example, if start and stop conditions are set to a fixed time trigger with the start
time set to 5:00 am and the stop time set to 8:00 pm, logging occurs each day
between 5:00 am and 8:00 pm.
If the start time were set to 8:00 pm and the stop time were set to 5:00 am, logging
would take place from the evening of the first day to the morning of the second day.
Notes Regarding the Start and Stop Conditions When Alarm or Level
Triggers Are Specified
• Operation if the stop conditions were already met at the point start
conditions are met
Logging starts from the point at which start conditions were met (A), and stop
condition scanning begins at the same time. At that point (B), stop conditions are met
but logging is not stopped. Logging stops at point (D) in which stop conditions were
met after point (C) prior to which stop conditions failed to be met the first time. (See
the following figure for the letters referred to in the text above)
