Unit_AnalogInput_FP0_A80Function block to read from an FP0-A80 unit.
This function block reads converted digital values from the analog input channels of the analog unit. The converted digital values are stored per channel in the output variables iInChannel0 to iInChannel7.
Input
Set the offset of the first WX/WY address of the analog unit according to its installation position.
For analog expansion units connected directly to the CPU (without adapter): Use ExpansionUnitToIOWordOffset_FP0 or make the following settings: 2 (WX2/WY2) for unit number 1, 4 (WX4/WY4) for unit number 2, 6 (WX6/WY6) for unit number 3
For analog expansion units connected to the CPU via an adapter: Use ExpansionUnitToIOWordOffset_FPX_FP0 or select the offset from the table.

No averaging: Conversion data is set for the specified input contact point area for each A/D conversion, on each channel.
Averaging: On each channel, for each A/D conversion, the maximum and minimum values from the data of the last ten times are excluded, the data from the other eight times is averaged and the result is set.
