Im using a performance equation to calculate the consumption per hour ENRGY_CONS=TAGVAL(ENERGY_TAG,'*')-TAGVAL(ENERGY_TAG,'t'+HOUR('*')*3600) and the schedual is 1:00:00,00:59:59.
ENERGY_TAG scan is every minute 00:01:00,00:59:59
Then in vantagepoint reporting sofware im retrieving ENERGY_TAG and ENRGY_CONS every hour for 24 hrs
00:00 ENERGY_TAG ENRGY_CONS
01:00 ENERGY_TAG ENRGY_CONS
it is supposed if i substract ENERGY_TAG at any hour from the next hour should get the same ENRGY_CONS value..but this not happening and there might be some difference.
I think this because of difference of the scan time ,there is one minute difference between tag scan and equation schedual scan. How can make them in the same time..or if there's any other ideas...will be appreciated
