This FB can optionally display a characteristic function or a curve function y=f(x), the X axis being
the input signal and the Y axis being the output signal.
• A limitation of the input value can be set in C00961/1 (upper limit) and C00961/2 (lower limit).
• The output value is internally limited to ±199.99 %. If a limitation of the output value is active,
bLimit is set to TRUE.
