CHAPTER 12: USER INTERFACE
12.1 Screen
Navigation
The screen navigation on the XLe/XLt is quite flexible. Basic methods will be described here. Control
programming can be used to create complex screen navigation techniques.
One form of screen navigation is the Jump Screen graphics object. This object is typically tied to a soft
key (One of the four keys to the sides of the display for the XLe and at the bottom of the screen for the
XLt). Pressing the soft key will switch to the screen that is programmed.

Screen jumps can also be triggered on other keys or based on control logic for more advanced
applications. To allow the operator to change screens, a screen jump object is generally used. This
object may be visually represented as a button (responding to touch) or remain invisible and logically
tied to an OCS register. An optional system ICON may be configured for display along with the legend,
which aids in identifying the object as one that causes a screen change.
