===== Detailed Function Description =====

The block is used to select a value from multiple inputs. Based on the //Select// parameter, the minimum, maximum, or average value from the inputs is transferred to the output. If there are fewer than four actual inputs, the other inputs should be managed so they do not affect the output, for example, by connecting them to another input.
