Processing details
■Subtraction processing
This function block subtracts values with coefficients and bias from the values input from the input variables IN1 to IN5 and
outputs the result from the output variable OUT_.
Input (IN)
IN1 to IN5
IN1 to IN5: Input, K_1 to K_5: Coefficient, B_: Bias
When no value to be input exists for any of the inputs (IN1 to IN5), input 0.
Ex.
When values are input only for IN1 and IN2
The value output from the output (OUT_) will be calculated as follows: OUT_ = (K_1  IN1) - (K_2  IN2) + B_.
