SCL2
z 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
2005 as 0000 to 0FA0 hexadecimal. SCL2(486) is used to convert (scale) the value in CIO 2005 to a
value between –0200 and 0200 BCD.
When CIO 0.00 is ON, the contents of CIO 2005 is scaled using the linear function defined by ∆X
(0FA0), ∆Y (0400), and the offset (07D0). These values are contained in D100 to D102, and the result is
output to D200.
