6.3 Linearization
The input values of the input can be linearized via a table.
This feature can be used e.g. to realize linearizations to specification for non-linear curves.
The “
Lin” table is always used when S.Lin = 1: “Linearization to specification” is set in INPm. The input
signals are filled in in units of the physical quantity (scaling result).
Non-linear signals can be linearized using up to 32 segment points. Each segment point comprises an input ( In.1
… In.32) and an output (Ou.1 … Ou.32).
These segment points are interconnected automatically by straight lines. The straight line between the first two
segment points is extended downwards and the straight line between the two highest segment points is extended
upwards, i.e. a defined output value for each input value is provided.
With an In.x value switched to OFF, all further segments are switched off.
+
Required: Condition for the input values is an ascending order.
In.1 < In.2 < ...< In.32.
