Hello everyone,
I was asked to gather the operation time of an exchanger over a period of one month. Time of operation of the exchanger ranges from ~10 to ~50 hours over that period of time. I have a tag number 'EGP.958TmI-0514B:Value' that records the total amount of time of that exchanger in operation. The raw data would look something like this...(note: counter resets everytime the exchanger is regenerated)
02-Dec-13 08:30:00 1
02-Dec-13 08:30:00 2
02-Dec-13 09:30:00 3
02-Dec-13 10:30:00 4 <-
02-Dec-13 11:30:00 0
02-Dec-13 12:30:00 1
02-Dec-13 13:30:00 2 <-
02-Dec-13 14:30:00 0
02-Dec-13 15:30:00 1
02-Dec-13 16:30:00 2
02-Dec-13 17:30:00 3 <-
02-Dec-13 18:30:00 0
02-Dec-13 19:30:00 1
02-Dec-13 20:30:00 2
02-Dec-13 21:30:00 3
02-Dec-13 22:30:00 4
02-Dec-13 23:30:00 5 <-
03-Dec-13 00:30:00 0
I want to retrieve just the maximum values over that time period (e.g. in this case [4;2;3;5]). How do I do that? Thanks.
