3.17.10.2 Functionality
The analog value scaling function SCA4GAPC is used for scaling the analog value. It
allows creating events from analog values.
The analog value received via the AIn_VALUE input is scaled with the Scale ratio n
setting. The scaled value is available on the AOn_VALUE output.
Analog input range is from –10000.0 to 10000.0.
Analog output range is from –2000000.0 to 2000000.0.
If the value of the AIn_VALUE input exceeds the analog input range,
AOn_VALUE is set to 0.0.
If the result of AIn_VALUE multiplied by the Scale ratio n setting exceeds
the analog output range, AOn_VALUE shows the minimum or maximum
value, according to analog value range.
