our customer collect data from MBUS for energy data. There are 800 Tags collected. We need to know if a MBUS is bad and we need also to know the last good recorded Value. The Analysis should keep runing with the last knowing good value. Therefore we decieded to set up the Interface that questionable values are stored in PI with Value and questionable flag.
But now we have the problem that i can't use this value for other caluclation. Is there a configuration so that i can use this values for the calculation.
