"2 state" versus "4 state". Not all tags will have all the states shown in these examples. Alarms have only state 0 and state 1 and therefore must use the "2 state" version of this widget.
Digitals might only use two states, but they can have four and therefore must use the "4 state" version of the widget.

The Text Change tag widget is used to represent the associated tag's value as a text string that changes (text or color) based on the tag's value. While this widget is available to analogs, it is most commonly used with digital and other tags that have clearly defined states (values from 0 up to 3).
If linked to a tag that has values above 3, this widget uses the modulus (remainder) of the tag's value divided by four. For example, 7 is read as 3.

Display Options
Style
Optionally, select Style Settings Tags to control the colors shown by the light, in response to the linked tag's value and alarm state.
Font
Select one of the font tags (or parameter linked to a font tag) that you wish to use to display the text. The display will use the default system font if you do not select a font tag.
Note: While it is possible (and very easy) to modify the appearance of the text within this widget using the Format ribbon of the Idea Studio, you will find it much easier to manage a group of similar controls by defining a font tag and selecting that for each. Changes to all can then be made by adjusting the properties of a single font tag.

Sets the position of the text within the display area. You may select left-aligned, right-aligned or centered. To align the display area itself with other elements on the page, see: Alignment and Positioning Tools.
Vertical Alignment
Sets the position of the text within the display area. You may select top-aligned, bottom-aligned or centered. To align the overall widget with other elements on the page, see Align.
