L_OffsetGainP_3

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 %.
