Supported platforms: CODESYS 2.3, CODESYS 3.5
SCD_LinearScale function scales ADC value to some calibrated unit linearly (e.g. to bar).
High, low and measured input variables are given to the function as ADC values (all with the same scale).
The function supports both positive and negative slope.
The function doesn’t limit the return value between i_LowScaledValue and i_HighScaledValue.
