8 Adding historization

In this section, we will add historization to the values of the data variables of the "Light" object.

8.1 Configuring the historization of data variables

  1. Open the object types list by clicking on the "Object Types" tab on the left side of the atvise builder interface.

  2. Open the object structure of the "Light" type and right-click on "COMMANDS -> LightIntensity".

Adding historization to the "LightIntensity" data variables

You can add "Smoothing" like absolute deadband to your data variables to reduce the amount of historized data - see chapter Smoothing.

8.2 Viewing the history in the visualization

Now we can take a look at the history list in the visualization.

  1. Open the "Office_Light" display in the visualization.

  2. Change the "LightIntensity" for some rooms several times.

  3. Click on the history list symbol histlist_symbol in the control panel to see the value changes in the history list.

You could also place this symbol in any display you like by using the display object "Historylist" in the "Standard -> hmi" folder.
