Overview Block Statistics

This control element shows recorded values as a chart – for instance the yield of the photovoltaics over the day, room temperatures of the last week or the consumption of a year.

Operation

Statistics on the page
  1. Chart symbol: shows that a recording is available here.
  2. Value and circle: depending on the setup the current value; the circle shows it in relation to the configured range. Otherwise a large chart symbol is shown here.

A tap on the element opens the chart.

Setup

This section is meant for the installer of the system.

The control element is linked to the function block Statistics block, which records the values: first create the function block and its addresses, then right click on the control element and select the function block. Without a link a tap on the element points this out. See also the notes under Project statistics.
