5.3 Widgets
A widget is a graphic element that a user interacts with or is used to build graphical user interfaces or GUIs. In the
case of the recorder, the user constructs a GUI using the Display Builder using widgets. There are two basic
types of widgets – Bars and Digital Displays. Trends, while treated as a widget in the Display Builder, are an
autonomous class and are dealt with in the Trends section below.
5.3.1 Digital Displays
There are two types of digital displays: full size and half size. Up to 12 full size and 24 half size digital displays
can be placed on the GUI.
The half size digital display widget is 2 blocks across by 1 block tall. It shows the Point
Tag – up to 8 characters and the Engineering Units up to 7 characters. It can display up
to 10 digits of data.
The full size digital display widget is 2 blocks across by 2 blocks tall. It shows the
Channel Tag – up to 8 characters and the Engineering Units up to 7 characters. It can
display up to six large digits or eight smaller digits of data.
