So you are using a WinCC Advanced Runtime V15. If you use a trend then you can choos between a cyclic trend ("live") then is only buffered up to max 999 values or a historical trend. therefore you have to create a data log in historical data. then you also have to choose a Tag for the logging. If we get more detailed information from you then we should be able to help better... Bye Murof
