The Signal Selector (SGSL) function block selects the maximum, minimum, or average of as many as sixteen input values and places it at the output. The block supports signal status propagation. There are no modes or alarm detection in the Signal Selector function block.
IN1 through IN[n] are the analog input values and statuses (as many as 16 inputs).
OUT is the selected analog value and status.
The following figure shows the internal components of the Signal Selector function block:
