Changing the order of 10 pumps by operation hours

Traoter

Hello,

Can somebody help me to create a function or is there a S7 function already for changing the sequence of 10 pumps by operation hours.
For example:
The sequence is set to : 1-2-3-4-5-6-7-8-9-10 and after 24 hours the program must changes the sequence and put the pump with less operation hours at first then the second, etc, etc.

Hi,

I need to do this for 5 pumps only.

Can you help me with a function/sequence?

Thank you!

Here is a small example for sorting data.

Change it according with your needs. 

Hi

One point to consider:

You may need consider some pumps to run less hours.

Should You run them in a way all of them have similar runtime

they will wear evenly and require maintenance roughly at the same time.

In water plants they usually run them in ratio 2:1 (2 pump installation) to ensure

one pump has plenty of remaining running hours when other requires maintenance

and/or repair.
