Hello!
How accurate would someone say a timer is in a L71 PLC?
I'm tasked with displaying a total water pumped using a flow meter over X time. The unit in GPM, if I capture the flow every one second and add each value until the end of the flow time, then divide by 60, that should be my total water pumped.
If I want to be more accurate, maybe I could capture the flow value every 500ms with a little more math. This would net me double the resolution. What if I went every 50ms?!? The scan of the program is going to limit me at some point..
I hope this interest anyone... Thanks!
