● When the number of retrieved analog input data has reached the set number of averaging
times (64 times or 128 times), averaging is performed for the number of times and the results
are stored as digital values.
● If the number of retrieved data is less than the set number of averaging times, the data
retrieved for the first time is stored in the external input area (WX).
(Note 1) To make the explanation simple, the above figure shows the processing which averages five points. In
the actual processing, calculation is carried out with the average of data for 64 times or 128 times.
■
Method for setting the number of averaging times
The number of averaging times can be changed by being written to the output relay area (WY)
in a user program.
5.1.3 Enabling Averaging Processing Setting
