Processing details
This instruction samples input values (E1) at data sampling intervals (ST) by the number of samples (SN), stores them in the
dead time table, averages the number of collected data blocks (SN), and outputs the result.
• The data refreshing cycle is "data sampling interval (ST)execution cycle (T)". (The resultant value is rounded off to the
nearest whole number.)
• When the dead time table is filled with the number of sampled data blocks (SN), the data sufficiency bit (BB1) is set to 0.
When the dead time table does not have sufficient data, BB1 is set to 1.
• Until the dead time table is filled with data, the past data is averaged and output.
• Processing is performed by ST=nT (n is an integer).

An overflow has occurred.
The sampling count (SN) is less than 0 or greater than 48.
The execution cycle (T) setting is less than 0.
The data sampling interval (ST) is less than 0.
(Data sampling interval (ST)execution cycle (T)) is greater than 32767.
