output of the interlock corresponding to the pressed button remains high even after the
button is released, until the next button is pressed.

Toggle Feedback
Toggle feedback is when the feedback of a button alternates between active and
inactive each time the button is pressed. As in the interlock, the toggle feedback
remains high even after the button is released, until the button is pressed again.
Because there is no way to communicate the state of the toggle button between the
panel and the control system by using that single button, Crestron models a toggle on a
one-way panel as a two-button interlock group. The button shown on the panel is the
first button. The second button (invisible, Crestron-created, not user-created) is the
original button's join number + 500, e.g. 1 and 501, 101 and 601, etc. Since there are
only 999 join numbers allowed by Crestron's RF protocol, a toggle button may only
have a join number of 499 or below. Be aware that you must not use the toggle join
numbers + 500 for other purposes. Crestron recommends that you keep toggle buttons
in one numeric range (such as 100-150) and then make sure you don't use anything in
the corresponding +500 range (600-750). When the user first presses and releases the
toggle button, the panel transmits the join number press and release. The next time the
user presses and releases the toggle button, the panel transmits the join number + 500
press and release, and then continues to alternate between them. By this method,
Crestron knows that the user is explicitly turning the toggle on or explicitly turning it
off, so that the state on the control system and the state on the touchpanel will match.
The programmer must place an INTERLOCK symbol in the SIMPL Windows program
and connect the join number and the join number + 500 to it. The feedback
corresponding to the original join number should be used to drive the logic
corresponding to the toggle being turned on, and the feedback corresponding to the join
number offset by 500 is used to drive the logic corresponding to the toggle being
turned off. See the following figure.

Duration Feedback
A button defined with duration feedback will remain active for a fixed period of time
as programmed in the Duration field. Active duration is d0efined by selecting
Duration as the feedback type, and entering a number of seconds in the Duration field.
The programmer should add an MV (one-shot) symbol to the SIMPL Windows
program, with the appropriate time parameter, as shown in the following figure.
