(3) Moving Average
The inputs into the designated channel are accumulated for the presser number, and its
average is calculated and outputted in digital data. However, in moving average method,
each scan provides its average value.
(1) In case of time/cycle averages. The input value is not outputted at every conversion, but the
previous value is maintained until the average time or cycle is reached.
(2) In case of moving averages, the converted input is averaged with the previously entered
value and the result is outputted at every conversion. Therefore, data response is faster than
time/cycle averaging methods.
(3) The three averaging methods can be processed simultaneously with the filter function
described earlier. In such case, the filter function is executed first, and averaging function is
processed to output the average value in digital data, which is expressed with the finally-
processed value.
