14.5 Ladder Based Screen Navigation

Ladder logic can use several techniques to control screen navigation. Coils can be tied to %D registers to
make them screen coils. These coils have two modes, switch and alarm. If the ladder program energizes
an alarm display coil, the screen associated with this coil is displayed and overrides the normal user
screens. This is designed to show alarm conditions or to display other ladder-detected events. When the
text coil is de-energized, the previous screen that was being viewed before the alarm is returned.
The switch display coil switches to the associated screen when it is energized. Once it is de-energized the
screen remains until it is switched by the user or ladder.

There is also a system register that can be used to for control-based screen navigation. %SR1 can be read
to determine the current screen or written to change the current screen.
Refer to the on-line help in Cscape for more information on control-based screen navigation.

14.6 Beeper Acknowledgement

The EXL10/XL10 PRIME contains an internal beeper that provides an audible acknowledgment when an
operator touches a graphic object that accepts touch input. When the graphic object is enabled, a short
5mS tone is emitted. When the graphic object is disabled, a longer 100ms tone is emitted to enounce that
graphical object is not currently accepting the touch input.
If beep acknowledgement is not desired, the beeper function can be disabled from the System Menu.
