L_GainOffset_2
This FB can amplify an analog input signal and then add an offset to it. Preferably to be
interconnected directly after the analog input terminals.
The internal calculations (addition and subtraction) are carried out with 32 bits without
overflow/underflow. Division is not remainder considered.
Gain and offset are selected via FB inputs.
The value provided at the
nOut_a
output is internally limited to ±199.99 %.
