Number of data sets per log file
You can use this parameter to define the number of data sets you want to be logged
per log file. The maximum number is 60,000.
Make sure that the number of data sets you select is only
as large as necessary so that the the time for logging will
be kept as short as possible.
Log when input values change
You can use the delta values in this section in order to specify the magnitude of
change in the actual value (when compared to the most recently logged value) at
which a new save operation should start. You can set a delta (ΔI1 through ΔI4) for
the four analog values at DL_I1 through DL_I4. Please note that all data will always
be logged with each log operation.

Fig. 233: Example of data logger as a ring buffer
