WinCC trend is only show values for 2 months as configured in the tag logging archives. But older values which are available in PH are not shown in the WinCC trend window. ------------------------------------------------------------------------------------------ Split from Process Historian Archiving.

You can display the saved process values and messages, as usual, on the process screen in Runtime in WinCC Online Trend Control or WinCC Alarm Control. Furthermore, you have direct access to archived process values and messages using defined interfaces, such as OLE-DB. In this way, you can make available important production data, for instance, throughout the company for analyzing purposes. For displaying the data from the PH you need to make a selection for a timerange of data, which are in the PH. Regards Georg Berghof

But still the WinCC trends are showing data of last 2 months as configured in the local server tag logging configuration. Not reading the values from the process historian. Is there any setting which I have to enable? PH communications are healthy. Thank you Regards Arun
