III-2 Non-linear functions
III-2.1 LINEAR (linearization function (No. 07))
Block LINEAR can be used for calculation ofy=f(x).
Max. 11 adjustable segment points for simulation or linearization of non-linear functions are available. Each segment
point comprises input x(1) and output y(1).
The segment points are connected automatically by straight lines. Each input value x1 has a defined output value y1.
With an input value x1 smaller than parameter x(1), the output value is equal to the y(1) value. If input value x1 ex -
ceeds the highest parameter x(n) value, the output value is equal to the relevant y(n) value.
The condition for input of configuration parameters is that values are input in ascendant order (x(1) < x(2) <...< x(11)).
The end of value pairs is marked by the “OFF” value in the next input value x(n+1).
This function block is cascadable. It has 2 inputs: The 1st input provides the variable which must be linearized. The
2nd input (case) is used to connect the previous linear block.
