Using Automatic Control Module it’s possible to send 2 commands by one button click. But scheme buttons can execute an action only on press down. For SCADA systems, especially web based, having 2 events (button down and button up) is a bad approach because it can cause sending wrong commands.
What action do you need to run on such buttons?

Where is the data stored before it is displayed on the web server?
You can copy the data files to Windows and view them by the utility.
When I view the table on the web station the data is from the first acquired data, it does not change as if it is frozen.
This is odd. Could you provide a link to a screenshot?
1. Search for browser kiosk mode. It’s already solved.
