Unity Pro - Comparison

[fred munger]

Hi, I want to program a sequence for fan selection. I have to compare the values (in time) for all the 12 fans to select the one with the lowest value. Is there a simple way to do that, a FFB that compares many values (REAL) to sort the lowest one (output in BOOL) ? Thx ! Edited July 23, 2013 by fred munger

Haven't ever touched Unity, but most PLCs with IEC command set have a MIN and MAX command. They would compare a range of values and give you a number saying which was lowest.
