SCL2
 Scaling 1 to 5-V Analog Input to –200 to 200
In the following example, it is assume that an analog signal from 1 to 5 V is converted and input to CIO
3 as 0000 to 1770 hexadecimal. SCL2(486) is used to convert (scale) the value in CIO 3 to a value
between –0200 and 0200 BCD.
When CIO 0.00 is ON, the contents of CIO 3 is scaled using the linear function defined by ∆X (1770),
∆Y (0400), and the offset (07D0). These values are contained in D100 to D102, and the result is output
to D200.
