    In Rapid SCADA v4 we used MSSQL Compact for storing configuration database. It is very close to SQLite. This approach was so inconvenient. I agree that SQL is a powerful language, but comparing pros and cons, the file based projects that can be easily uploaded and downloaded are preferable.

    It’s possible to use an RDBMS instead of BaseDAT\*.dat as a runtime data source. We will implement it if found a sponsor.

    Hi,
    v6 is a high priority project, it will be continued for sure.
    However, we provide fixed due dates only in case of working on a contract.

    This issue is interesting and unusual. Considering the fact that we anyway will rewrite the entire web application, I suppose, we should check the new web app if this issue still occurs and then fix it.
    dotNET5 doesn’t support WebForms technology that is currently used that’s why we have to create the web app from scratch.

    The subnodes are the channels grouped by device. That’s why subnodes are the same. All devices are displayed.

    Hi,
    In formulas, only limited amount of information is accessible. To access to the configuration database and archives, you need to develop a module using C#.

    Yes, the issue is reproduced. But demo server has very low CPU and RAM.
    What are the parameters of your server? Is it Linux or Windows?

    As an option, I would develop a utility to export XML and/or DAT files to the required RDBMS.

    If we found a sponsor, we can implement uploading a project from Administrator to PostgreSQL database.
    In my opinion, SQLite is not enough, because remote access is quite useful in many cases.

    Yes it is, see v5.1.4.2
    Server update for testing.
    The command queue is in the Server service.

    Thanks for the useful notes. Some comments below.

    I then went through Administrator on windows and changed all localhost settings to now look at the remote server eg. 192.168.1.10

    Could you provide a screenshot of this to check?

    This is most likely a config issue but I had to re transfer all the plugins to the Rpi opt/scada/ folder

    DLLs of the modules should be presented on RPi. WinSCP is good for file transfer.

    To activate the ChartPro plugin, I had to go chmod ug+rw WebSettings.xml

    This is a known issue. We will fix it in the future.

    Please open the properties of KpEmail.dll and check the version. What is the file version?

    Also try specifying a particular email:

    Hi,
    You can’t send a command from a formula. However, you can set input channel value from a formula.
    To send commands according to conditions, Automatic Control Module was created.

    Currently to export data on change, use the existing DB export module.
    The version 5 can only export data to 3rd party DB. Flexible archives possible in v6.

    Output channel only declares a command. It doesn’t send command itself, and it doesn’t store any value.
    To display any kind of value, you need an input channel which stores a value.

    Hi,

    If you need to send commands automatically according to some conditions, Automatic Control Module would help you.
