DEMUX: Demultiplex

Description

You can use the instruction "Demultiplex" to copy the content of the input IN to a selected output. In its initial state the instruction box contains at least 2 outputs (OUT0 and OUT1). The number of selectable outputs can be extended in the instruction box. The outputs are numbered automatically in the box. Numbering starts at OUT0 and continues consecutively with each new output. You use the K parameter to define the output to which the content of the IN input is to be copied. The other outputs are not changed. If the value of the parameter K is greater than the number of available outputs, then the content of input IN is copied to the parameter ELSE and the enable output ENO is assigned the signal state "0".

The instruction "Demultiplex" can only be executed if the tags at the input IN and at all outputs are of the same data type. The K parameter is an exception, since only integers can be specified for it.
