Processing details
■Multiplication processing
This function block multiplies the values input from the input variables IN1 to IN5 with coefficients and bias 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 1 to both the input and coefficient.
When either input or coefficient is set to 0, the bias (B_) will be output (OUT_).
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_.
