a linear image of a part of the input. A retrograde calculation function is realised by using the linear
imaging function inversely. A cascading of several Output Splitters is supported by an integrated
decision table for the combinability of inputs and outputs.
Fig. 66: Schematic presentation function block Output Splitter
Function block Signal Characterizer
The function block "Signal Characterizer" has two channels the outputs of which are not in linear
relation with the respective input. The non-linear relation is defined by a look-up table with individu-
ally selectable x/y-pairs. The respective input signal is imaged on the corresponding output, hence
this function block can be used in a control loop or signal path. Optionally the function axis can be
exchanged in channel 2 so that the block can be also used in a reverse control loop.
