We are setting up a PI Vision screen that displays run time of pumps since last maintenance. What way have people set up their AF / PI tags to reset the counter when maintenance is complete? monitoring asset maintenance pump running time
You need a way to get the date of last maintenance into an attribute so you can use it as the start time of your run time calculation. Ideally this attribute would update automatically via a PI Tag (manual data entry perhaps) or through a linked table lookup: ideally, the link would be to a maintenance system that is updated when maintenance is done or perhaps to an Excel sheet where the date is entered manually (less than ideal, but workable). If these are not possible, the date could be manually updated directly in an AF attribute.
Please let us know your thoughts.
I suggest keeping lifetime totals in PI - and not do a reset of the tag to zero. You can always get the delta - for last 30 days, 90 days, last service date etc. from the lifetime totals.
