16.1.31 L_OffsetGain_2
This FB can add an offset to an analog input signal and amplify it afterwards. 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.
Offset and gain are selected via FB inputs.
The value provided at the nOut_a output is internally limited to ±199.99 %.
