Mean Value Processing
The Analog Input Unit can compute the mean value of the conversion values
of analog inputs that have been previously sampled. Mean value processing
involves an operational mean value in the history buffers, so it has no effect on
the data refresh cycle. (The number of history buffers that can be set to use
mean value processing is 2, 4, 8, 16, 32, or 64.)
When “n” number of history buffers are being used, the first conversion data
will be stored for all “n” number of history buffers immediately data conversion
has begun or after a disconnection is restored.
When mean value processing is used together with the peak value hold func-
tion, the mean value will be held.
Specify whether or not to use mean value processing and the number of his-
tory buffers to be used for mean value processing.
For the DM word addresses, m = D2000 + (unit number x 100)
Note
After making the DM settings from a Programming Device, it will be necessary
to either turn the power to the PLC OFF and ON, or turn ON the Special I/O
