Unit_AnalogInOut_FP0R_A42Function block to write to and read from an FP0R-A42 unit.
This function writes digital data to the analog output channels of the analog unit and reads converted digital data from its analog input channels. The digital values to be converted and output as analog values are specified at iOutChannel0 and iOutChannel1. The converted digital values from the analog unit are stored per channel in the output variables iInChannel0 to iInChannel3.
The analog output and input ranges are also set with this function block.
The voltage or current output must be set with the DIP switches.

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.

Set the digital value to be converted and output by the analog unit.
Set the voltage or current range for the analog output channel.
Set the voltage or current range for the analog input channel.
Output
TRUE when I/O configuration is completed and the unit is ready.
Returns the converted digital data from the analog unit by channel.
DIP switches 1 and 2 must be ON to use 14-bit mode. DIP switch 3 is used to set voltage or current output for channel 0, DIP switch 4 is used to set voltage or current output for channel 1, and DIP switch 5 is used to turn averaging on or off.
The DIP switch settings will become effective when the power is turned from OFF to ON.

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.
