Hello, "If you use a user-defined data resolution with a combination of "Resolution" and "Quantity of data", it is possible that the amount of extracted data is not correctly determined. This results under certain circumstances in a mismatch between the displayed values and the configured quantity of data." -> This explains why you are not getting the desired number of entries as per the logical time calculation. Also mentioned in the manual which might be useful information for configuring reports: If you use the option "Quantity of data" in "User-defined resolution", enter an even value in the input box. Even values ensure a trend-true display. --> These are recommendations provided in the WinCC manual. Also, even though we are using user defined resolution, the data will be generated internally but what is displayed will try to match the resolution provided by the user. I have attached the extracts of the WinCC Data Monitor 7.5 SP1 Manual which might be of use to you. An alternative way to validate your data against your other project could be by using the excel export data option on the Online Trend Control in WinCC for the desired archived tags. Hope this helps! :) |
