Editing a preset

You can edit the presets you created or uploaded.

To edit a preset:

1. In the main menu, select the Presets section.
2. On the opened page, select the relevant preset from the list of presets on the left.

   The table on the right shows all tags that are included in the selected preset.

   If necessary, change the position of the tags in the table. To do this, drag the desired tag up or down in the asset tree by the dots () to the left of its icon.

3. Click the Change preset () button next to the selected preset.

   The Edit preset window opens.

4. If required, enter the new name of the preset in the Preset name field.

   You can also modify the preset name in the preset list. To do this, double-click the preset name, in the opened field enter a new preset name, and press ENTER.

5. If you need to change the preset icon, click the Choose icon button and select the appropriate icon in the opened window.

   You can upload a preset icon by clicking the Load icon button. Images of any format larger than 128x128 pixels are shrunk to 128x128 while maintaining the aspect ratio. The size of the uploaded image in SVG format must not exceed 200 KB.

   If you want to delete the preset icon, click the preset icon and then click Delete in the opened window.

6. If you want to add an expression for calculating tag values to display them on a graph in the Time slice section, do the following:
   1. Turn on the Configure expressions for Time slice toggle switch.
   2. In the X-axis caption field, enter the caption to be displayed on the x-axis.
   3. Click the Add expression button and specify the following values in the drop-down section:
      • In the Expression name field, enter the name of the expression.
      • In the Y-axis caption field, enter the caption to be displayed on the y-axis.
      • In the Expression for calculation field, enter an expression for calculating tag values.

        You can define expressions with simple arithmetic operations (such as addition, subtraction, multiplication, and division). For example, if the sensors are reporting temperature in Fahrenheit, you can use the following expression to display the temperature in Celsius:

        5/9 * ($tagValue - 32)

        If necessary, you can add multiple expressions for the Time slice section.

      • In the Graph color field, select the color of the graph that will be displayed for the preset in the Time slice section.
   4. To delete an expression from a preset for the Time slice section, click the trash bin icon () in the lower-right corner of the expression section.
7. If necessary, add tags to the preset by selecting the check boxes next to the relevant tags in the list of tags below. You can search for tags by entering the tag name in the Search by tag name field.
8. If necessary, clear the check boxes next to the names of the tags that you want to remove from the preset.
9. Click the Save button.

The changed preset will be updated in the list of presets in the Presets section and in the drop-down list of presets in the History and Monitoring sections. The changed preset for which step 6 of these instructions was performed will also be displayed in the drop-down list of presets in the Time slice section.

If necessary, you can change the position of presets in the list of presets. To do this, drag the preset up or down in the list by the dots () to the left of its icon.
