Parameters
Function
The Select value defines which input value is sent to the output.
Values received on unselected inputs are stored until the input is selected.
The output is recalculated and updated every time if any of the inputs or Select receives a value.
Select starts with a 0.
Exception handling
If the value on the selected input or in Select is invalid, the output will not react.
Output E (Error) is set to 1. It resets to 0 as soon as both Select and the selected input have valid values.
Other
If an unlinked input is selected, the output value remains unchanged.
