Run time balancing 4 dry coolers

[alyudedu]

Hello everyone,

I need to write a program to run 4 dry cooler units with run time balancing. Number of units to run must be chosen according to demand and total run time, if there is any, faulty units must be ignored in the rotation chain. I have managed to create a program with using seq blocks in menta editor but got unreliable results. Has anyone ever had a similar situation before? I appreciate any kind of help.

I am using EcoStruxure Building Operations(3.2.3.59) and the controller is an AS-P.

There are quite a few examples of this in the EcoStruxure Building Operation forum, particularly the NAM Standards Central Plant Rotation Programs
