In the above example, all samples for the average are stored in input locations.
This is necessary when an average must be output with each new sample. In most
cases, averages are desired less frequently than sampling. For example, it may be
necessary to sample some parameter every 5 seconds and output every hour an
average of the previous three hours’ readings. If all samples were saved, this
would require 2160 input locations. The same value can be obtained by
computing an hourly average and averaging the hourly averages for the past three
hours. To do this requires that hourly averages be stored in input locations.
Instruction 80 is used to send the 1-hour average to Input Storage and again to
send the 3-hour average to Final Storage.
