Scaling 1 to 5-V Analog Input to 0 to 300
In the following example, it is assumed that an analog signal from 1 to 5 V is
converted and input to CIO 2005 as 0000 to 0FA0 hexadecimal. SCL2(486) is
used to convert (scale) the value in CIO 2005 to a value between 0000 and
0300 BCD.
When CIO 0.00 is ON, the contents of CIO 2005 is scaled using the linear
function defined by X (0FA0), Y (0300), and the offset (0). These values are
contained in D100 to D102, and the result is output to D200.
