    What would be a good approach to log fast inputs (0.1s.-0.2s.) and fast outputs (0.3s) to Rapid scada? Even with adjusting poll rate and data refresh rate, it is not too reliable. Any suggestions to improve this? Thank you.

    Seems, that a good approach would be to change a communication protocol. It would be more efficient to receive bunch of data that contains many data points.

    Currently, while viewing data is one value per minute. Is it possible to make it to record more often? Just for a selected channel, not all of them.

    It can be adjusted from 1 second. To do this, create the appropriate archive and specify it in the channel mask. Make an additional table with the Archive code. If necessary, configure the profile of the Charts Pro for display.

    You can write data on change. It is supported by PostgreSQL archives.

    It’s needed to create a new archive in the configuration database and in the Server settings. The created archive should not be marked as default. Then you can set an archive mask of the channel to write that channel to the certain archive.
    Ask for the details if needed.

    I have to ask for the details. I created an archive in Server tab, but cannot see it in the configuration database tab. So I assume, I have done something wrong. Or, I just don’t what I am doing.

    After creating the archive, it must be assigned in additional project tables by analogy with the existing ones.

    Manually add a row in the Archives table.
    If you provide screenshots, I can check.

    Your archive is listed as the Current one, which is probably incorrect. It must be Historical beforehand

    Is there a way to check if there is actually anything written in that archive I created?

    1 Download additional utilities and replace them with new libraries from the Scada package.

    2 Configure the Presentation Table and Chart Pro to display this particular archive
