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