DATA LOGGING FUNCTION
POINT
(1) Since general data sampling is not synchronized with the control CPU's
sequence scan, data separation may occur.
 Section 3.2 (5) Access units
To perform data sampling synchronized to the sequence scan, use high
speed data sampling.
(2) Data changes occurred between the data sampling processes are not sampled
because a high speed data logger module only samples data from a
programmable controller CPU at the specified data sampling intervals.
