3.17.9.2 Functionality
The analog value scaling function SCA4 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.
