    Performance equation  to calculate the consumption

    Waly@osi

      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

      I hope the point is clear

      Thank you
