    Hello, thank you for your help. I would like to ask how to read the xx.dat content information of the Archive?

    Use the TrendTableViewer utility to view data.

    I have downloaded and opened the file. I configured “Archive” in the Channel, but when I opened the downloaded file with the software you provided, I didn’t find any data. I confirmed that the file size is 4M. When I changed the file to another device, it also displayed as shown in the picture. Is this normal? Thank you!

    It looks like there is not data in the archive.
    Try opening the default archive written by the HelloWorld project.

    I tried to run the HelloWorld project for about ten minutes, generating records every minute. When I opened it, I still didn’t see any data. The pictures were the same as before. Could you please help me take a look? Thank you!

    Please check the selected “Trend table directory”. Does it contain data files?
    Can you view historical data via the web interface?

    Likely, the directory that are set by default does not exist. Choose the correct directory by clicking the Browse button.

    Look at the latest pictures I sent. All the files have been recognized. I have confirmed that there are files and they are all recognized, but they can’t be opened. This indicates that there are files and data. It seems that the tool software can’t open them. Could you please help confirm this? Thank you

    You need to replace the used dll files from the current version of Scada in the utilities

    Please make a screenshot of the C:\SCADA\Archive directory that is used in your screenshot.

    The problem has been solved. Just as you said, replacing the file has nothing to do with the directory

    By default, the utility uses the old path. It should be updated someday.
