Prevent PI-TAGs to be overwritten with new data for certain time range
Normally our TAGs are filled with data coming from an analysis (or PI-Equation) by snapshot-data or recalculated data. But sometimes we have to do manual corrections due to data loss and have to write data to this PI-TAGs manually. And we are not allowed to change these corrections afterwards (e.g. when our obligatory technical account is already done).
In this cases it would be great if I were able to configure (in AF) time ranges for PI-TAGs in which all archive data for these TAGs is locked and cannot be overwritten by other data (independent from where it comes from).
