17.1.33 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 %.

• High gain factor for further
processing of smallest input
signals.
• Please observe the difference
with regard to the gain factors of
other blocks in percent
(±199.99 % ≈ 2).
