Function Block LST: SCALED ANALOG INPUTS LESS THAN COMPARE
FUNCTION
This block function applies a scale factors to the inputs and then compare if the sum value is < than a
threshold.
The output boolean (True/False) value is obtained by the relation:
OUTPUT= TRUE
IF ((INPUT1 x GAIN1)+(INPUT2 x GAIN2)) < THRESHOLD
OUTPUT=FALSE
IF ((INPUT1 x GAIN1)+(INPUT2 x GAIN2)) >= THRESHOLD
