*: Setting available only when using a module with data refresh intervals including 1 ms.
Data refresh interval Automatically- or user-selected value per module
Automatically-selected value: The optimal data refresh interval is automatically selected
based on the recording interval setting.
User-selected value: Available settings depend on module specifications.
Repeat recording Off/On (user-selectable)

Off: Recording is performed once until it stops.
Specified time/
continuous
Specified time The recording time is set in days, hours, minutes, and seconds.
The time can be set up to the maximum capacity of the internal
buffer memory (total of 256 M data points).
Continuous Recording is performed once until it is stopped.
If the maximum capacity of the internal buffer memory is
exceeded, the memory will be overwritten.
Waveform recording
The last 256 M data points (when recording 1 analog channel; if recording n channels,
256 M/
n
data points) are saved in the internal buffer memory.
The user can scroll through and view data stored in the internal buffer memory.
Alarm source data recording can be toggled on and off.
Number of occupied channels (
n
)
When alarm source data recording is enabled
n
= Number of analog ch number of pulse channels × 2 + number of logic
channels × 1 + number of waveform calculation channels × 4 + 26
When alarm source data recording is disabled
n = Number of analog ch number of pulse channels × 2 + number of logic
channels × 1 + number of waveform calculation channels × 4
