I'm trying to totalize the Power used by heating elements. I have a current reading for the 3 phases, and calculate the total like this:
'Amp Phase 1'*.400*Sqr(3) // saved in attribute Analysis1_tot_kw / tag in Historian
if '*' = 't' then 0 else TagTot('Analysis1_tot_kw', 't', '*')*24
and write the results to pi tags. I have to say I'm new to totalizing, so I'm not sure if I'm using it correctly. I backfilled for 4 days, and the result looks like this:
The most recent result looks perfectly fine, but the one before is not making any sense.
Did I use the TagTot function incorrectly, or the backfilling?
TiA and Best Regards,
