Trend synchronization
Siemens
Building Technologies
Trends are synchronized to simplify evaluation of trend data.
The various query intervals are set up on an interval grid. The interval grid begins
at 00:00:00 hh:mm:ss.
A newly started trend displays the first data point at the first possible interval point
after start. The trend has the state "Incomplete" as long as this point has not been
reached; it then changes state to "In process".
