19.1.93 L_GainOffsetP_1
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 parameters.
• The value provided at the nOut_a output is internally limited to ±199.99 %.
