    Hello friends,
    I'm doing tests with controls communication for S7-200.
    My problem is I have for example a DigitalPanelMeter and BasicLabel. When I run my application the DigitalPanelMeter read properly until I change the value of BasicLabel.
    If I change the value of basicLabel or make a click on a BasicButton, the program does not returns to refresh the data.
    For the program to refresh the data I have to close and open the application.

    Am I doing something wrong? How I can fix it?

    A greeting and thank you very much

    Hello fellow,
    After doing more tests, do not always get stuck in the same way.
    I have always read a DigitalPanelMeter (the MW10) and I changing a value BasicLabel (MW12). Sometimes it does well up to 8 times and sometimes it misses the first change.

    How can it be?

    A greeting and thank you very much

    The Siemens driver is still considered a Pre-Alpha (prototype) version, so it will very likely have some issues. It may be a couple months before a good working Beta version is available.

    Ok, I'll wait a couple of months until the beta is finished and available.

    A greeting and thank you very much.
