1) It is possible to use the 0 to 5V range and 0 to 20mA range
together.
2) The A/D conversion data is set for the specified input contact
point area for each A/D conversion on each channel.
3) On each channel, for each A/D conversion, the maximum and
minimum values from the data of the last ten times are
excluded, and the data from the other eight times is averaged,
and the result set.
(Use when the environment contains a lot of noise.)
4) The switch reads only once when the power supply of FP0
control unit is turned on.

3.3Averaging Function for Voltage and Current Ranges
When the averaging function is set to on, the internal processing of the A/D conversion
unit is as shown in the diagram below (in this example there are two input channels, and
the input range setting switch Nos. 3 and 4 are off).
Starting with the most recent data, the data from the last ten times is taken. The
maximum and minimum values are deleted, and the averaging is carried out on the
remaining eight items. The obtained values are output to WX2 and WX3. The values
output at this time always use the most recent averaged value (decimals are discarded).

Conversion data switch flags
The resolution of the A/D converter unit is 12 bits, but when data is transferred to the
control unit, it is converted to 16–bit data. Therefore, although the WX2 data requires no
processing, for the WX3 data, the top two bits are used as conversion data switching
flags. Accordingly, the top two bits are processed as follows.
When the A/D conversion data is negative “–”, the WX2 and WX3 data become two’s
complement.
In other words, bit C to bit F of WX2 and bit C to bit D of WX3 become “1”.
Also, because the top two bits of WX3 are used as conversion data switch flags, masking
is required so that the bits are “00” when the conversion data is positive “+”, and “11”
when the conversion data is negative “–”.
