Functionality

The analog value event creation with 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.
