Create attributes on event frames

Create attributes on event frames in the same way as on elements.

1. In the Event Frames browser, find and select the parent event frame.

2. In the viewer, select the Attributes tab.

3. If no attributes exist, click the New Attribute link. Alternatively, click New Attribute on the toolbar.

   Note: If the event frame is based on a template, you cannot add an attribute unless the template allows extensions.

4. In the Name field, enter a unique name for the attribute.

5. In the Description field, enter a description for the attribute.

6. In the Properties field, select attribute properties as needed. For more information, see Set up attribute properties.

7. Optional. In the Categories field, assign the attribute to a category. To browse available categories, click .

8. In the Default UOM field, select the unit of measure for the attribute.

9. In the Value Type field, select the data type of the attribute.

10. To assign a value to the attribute, choose from the following actions.

    To ...	Do this ...
    Enter a static value	Type a value in the Value field.
    Derive or calculate a value from a data reference	Select a data reference type from the Data Reference list. Click Settings to configure the data reference. For details about configuring a data reference, see Understand configuration of data references.

11. Optional. When the Use DisplayDigits for Attribute and Attribute Template values system option is selected, you can override the default DisplayDigits property value of -5 and specify the number of digits to display in the Display Digits field. Only numeric values in the Value field are affected. For attributes that are not based on a template, the precision of PI point data references is obtained from the PI point itself.

    • Enter a negative number up to -20 to indicate the total number of digits to display.

    • Enter a positive number up to 10 to indicate the number of digits after the decimal point to display, including trailing zeros.
