Hi,

i have a problem that I am not looking for a complete soloution for but an opinion to see if it is possible. 

I am running a pump from output Q1. I know the output from the pump is 2 litre per min and I want to display the accumulative output in litres of the pump. I already display the run hours of the pump but this updates hourly however I would like to have a more accurate and as close to real time value for the volume of liquid pumped.

Currently I am using counters and counting hours, so a have maximum of 999,999 hours on a counter which equals about 114 years which is more than ample. However if I take the same approach to update the liquid consumption every minute this would limit me to just under 2 years of constant running before the counter maxed out. 

I am looking for alternative way and I am not seeing the path yet! I thinking I need to store a value and add to it. Is this possible or a step too far for the Logo!?

Any guidance greatfully accepted

I think i have solved it using Darren_T3's Run Timer UDF.

Thanks Darren_T3, should have read the board before posting!

Maybe there is an easy option to solve it. If your pump has 2 liter per minute, then it is 1 liter per 30s. Use a stop watch and increase a counter all 30s. With increasing also reset the stop watch with a one cycle signal.
