Hi guys!

How do you record the running time of the 3 pumps?

With the block operating hours counter of the LOGO! ?

In attachment is an example.

There was a lot of work to do there, I couldn't have done it by myself.

Thanks for your time!

 One more thing, please. I can't understand what is the difference between 'low word hours counter' and 'high word hours counter'. Because i need 'q1' 'q2' 'q3' to be: Motor(1,2 or 3) worked less than the others two and i need to change.

I already wrote.
The value of the operating hours counter is a 32 bit value.
But the LOGO! can work with the resources available for users only with 16bit values.
So you have to resolve the 32 bit value (DWord) in two 16 bit values.

Example:
The values of 2 operating hours counters are transferred to the VM area, double word VD0 (32bit) and VD4 (32bit). The double word VD0 consists of the words VW0 (16bit) and VW2(16bit). So VW0 is the high-order word in double word VD0, VW2 is the low-order word in VD0. The same applies to VD4, that's VW4 and VW6.
If the words of W0 and VW4 are then compared, and the value of VW0 is greater than the value of VW4, then the first hour meter has a greater value than that of the second. Then the comparison of VW2 and VW6 is no longer interesting.
If the comparison of VW0 and VW4 shows no difference, ie the values are the same, then you must compare whether the value in VW4 is greater than that in VW6.

 Now is clear :D . Thanks again.
