It is a selection function.

You change the state of the output with an boolean input.

The Variables In1 and In2 can be of any kind

example in ST

IF YourBooleanVariable THEN

YourOutPutVariable:=YourInputVariable1;

ELSE

YourOutPutVariable:=YourInputVariable2;

END_IF

Some call it a "Analog switch"
