Volume Mute – Toggle Feedback
22 • Crestron SIMPL Windows
Certain buttons may call for more complex feedback. For example, a volume mute
button may alternately turn the mute on and off. To indicate this with feedback, the
button should display in the feedback state when the mute function is on, and turn off
when mute turns off. Clearly, momentary feedback will not do the trick here, so we
must use logic symbols to generate the desired behavior. This example shows how to
do this using the Toggle symbol.
An even more elaborate form of feedback is possible when there is 2-way
communications between the control system and a device being controlled. In this
case it is sometimes possible (and desirable) to show feedback based solely upon
information received from the device (NOTE: this information is also called
feedback. Don't confuse this with button feedback). For example, suppose you are
controlling a switcher, which allows you to choose one of 4 video sources. If the
switcher itself sent information back to the control system detailing which source
was currently selected, your program could use that information to highlight the
button representing the selected source. This would guarantee that the feedback was
always correct, even if a user performed the switch from the switcher itself, and not
via the control system.

Subpages (touchpanels only)

Subpages are powerful objects available for touchpanels only. Subpages are in many
ways similar to standard touchpanel pages, in that they may contain buttons, text,
graphics, etc. However, subpages ordinarily do not take up the entire display screen
area. Instead, a subpage often defines a small area with buttons serving a specific
function, such as VCR control buttons. A given subpage can then be designed to
