Notes
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.
