Overview Block Statistics Live

This control element displays up to eight measured values in a live chart. In contrast to Block Statistics, the values are recorded continuously (live) directly in the control element and not logged via a function block.

The control element is available in two different views, Block and Basic Screen. Clicking on the control element shows the dialog with the chart. The display can be scaled horizontally via the +/- icons, the time range can be shifted with the left/right arrow icons. The time range is set via the button in the middle.

Menu

The button in the middle opens the menu in which the time range is selected:

Lines

The Lines button determines which of the up to eight values are displayed. The individual lines are selected or deselected via the checkmark.




Configuration

Link the values to be displayed directly on the control element. To do so, right-click on the control element.
