On/Off
Set this to On to perform rolling average.
Interval
Set the sampling interval for performing rolling average. The sampling interval takes on a
value that is an integer multiple of the scan interval. For example, if the sampling interval is
set to 5 s when the scan interval is 2 s, the actual sampling interval is 6 s.
Number of samples
Set the number of samples for performing rolling average.
The rolling average time is equal to the sampling interval × the number of samples.
Note
• If the number of data points to be averaged has not reached the specified number of samples
immediately after computation is started, the average of the available data is computed.
• Computation error data is excluded from the rolling average computation.
• If the computed data exceeds the upper or lower limit, the data is handled according to the
Value on Overflow setting.
If it is set to Error or Skip, the computed data is not used in the rolling average computation.
If set to Limit, the computed data is clipped at the upper or lower limit to compute the rolling
average.
The upper and lower limits are “±100000000” ignoring the decimal point. The decimal place is
the same as that of the span lower limit.
