Type Description (under LCD XY/MD Mode)
Destination Selects a destination.
When you configure a destination button, a drop-down menu appears:
'Destination Device' . Choose a device from the list. The 'None' entry is merely
a placeholder. Do not choose 'None' .
The button definition section also presents a "level set filter" drop-down list
in which you can select a level set to reduce the number of sources through
which to browse.
The button legend is the source name, unless you check 'Use Custom Button
Text' and assign the button your own text.
Destination Sets or removes a "lock" on the current destination device. The lock can be
Lock removed only by the user that originally set the lock, or by a panel that has
"Force Release" enabled.
The button definition has no fields to configure. Its legend cannot be
changed.
Destination Sets or removes a "protect" on the current destination device. The protect
Protect can be removed only by the user that originally set the protect, or by a panel
that has "Force Release" enabled.
Note: a protect prevents others from routing to a destination; a lock prevents
anyone — even the user who issued the lock — from routing to the
destination.
The button definition has no fields to configure. Its legend cannot be
changed.
Free Source Defines a phantom device that can be used to release or "free" devices on
the data (control) level. A free source is also used with tielines to free the
tieline for others to use. The free source is configured in the Level Set Details
page of NV9000-SE Utilities.
The button definition has no fields to configure. Its legend is arbitrary.
[Forward] The panel software can introduce a "forward" button if an automatically
generated list has more entries than can fit on a page.
A 'Forward' displays and activates the next button page in an automatically
generated sequence.
There is no explicit 'Forward' button type; configurers cannot create forward
buttons explicitly.
