The "Multiplex" instruction can only be executed if the tags have the same data type in all inputs and in the OUT output. The K parameter is an exception, since only integers can be specified for it.

MUX: Multiplex

Description

You can use the instruction "Multiplex" to copy the content of a selected input to output OUT. In its initial state the instruction box contains at least 2 inputs (IN0 and IN1). The number of selectable inputs of the instruction box can be expanded. You can declare a maximum of 32 inputs.

The inputs are numbered automatically in the box. Numbering starts at IN0 and is incremented continuously with each new input. You use the K parameter to define the input whose content is to be copied to the OUT output. If the value of the parameter K is greater than the number of available inputs, the content of the parameter ELSE is copied to output OUT and enable output ENO is assigned the signal state "0".

The "Multiplex" instruction can only be executed if the tags have the same data type in all inputs and in the OUT output. The K parameter is an exception, since only integers can be specified for it.
