Also adjust the Time range in the table control to 1 hour. You can synchronize the start time of the archiving by specifying a binary tag as Start tag...

Phantom75 Posts: 2661 Rating: (278)	The Online Table Control displays archived values & archive time.Youcan use the Start tag parameter in Tag Logging and Update parameter in the table control to acheive what you want to do. But it is very difficult to synchronize to the minute. In your case it is better to make your own table and you have two options for this: a) Create 24 tags in WinCC and every hour read the archive and populate these tagsusingGlobal Script. or b)Write the value every hour ina DB (with 24 reals)and display this DB in WinCC. The second option is better in my opinion. Regards

Case 1 It's possible create a "selective trend" and play with start/stop function and acquisition time to archive 1 value only Case 2 I'm agree Phantom75, the best slution should be synchronize plc with date-time and create integration function to store average value and trigger WinCC to archive value (with selective trend maybe) Regards
