The Data Item format dialog box is invoked by selecting Data Item from the Format menu, either on the main menu or from the context sensitive menu which you can pop up by right clicking on a data item object. The Data Item style lets you display the data item in a number of different styles from various numeric formats to textual display to graphic representations like Stripchart, Bargraph, Bitmap, etc. Depending on the format you choose you can set different properties of the display. Besides the display format you can also set the update properties and alarm properties of the item if is applies. The next few chapters will explore the Data Item Format dialog in detail since it handles many settings. The following image shows the data item format dialog:

The dialog is separated into left hand pane and right hand pane. On the left hand pane you can select the format you want the item to be displayed in. The right hand pane allows you to modify the properties of that particular format. Besides the Format Properties you can also change the Update Properties and the Alarm properties. In the dialog above the format Integer is selected and you can set the specific Integer type in the format properties tab. In our case it is set to Hexadecimal.

The numeric formats supported are Integer, and Float. The available text formats are ASCII, and Status Text. The graphic formats are Bargraph, Bitmap, Status Image, RGB Bitmap, and Stripchart.
Some formats also allow you to select alarm properties, in this case the dialog enables the 'Alarm Properties' tab that controls the alarm settings.
