VEGA VEGAPULS 61 (≥ 2.0.0 - ≥ 4.0.0) Foundation Fieldbus Approval according to LPR radio standard - Manual (Page 80)

The function block "Input Selector" offers selection possibilities for up to four inputs and generates an
output signal according to the selection criteria. Typical input signals are AI blocks. Selection
possibilities are maximum, minimum, mean value, average value and first useful signal. Through
parameter combination, the block can be used as rotary switch or as preselection switch for the first
useful value. Switch information can be received by other input blocks or the user. Mean value
selection is also supported.
