Configuration
Tally (GPIO) Window
 Navigation buttons do not jump to global suffix pages or global navigation pages. Only
global navigation buttons jump to global navigation pages; only category buttons jump to
suffix pages. However, the operator will probably see no appreciable difference between the
button types. See
Global Navigation on page 44.
When you double-click the page number field of a page you want to edit, the image of that
page appears in the panel graphic area.
The “Links to Page Num(s)” column lists, for any page, the other pages that refer to it. Using the
links column you can mentally examine the tree structure or create a sketch of the tree struc-
ture. You might note that if the link field of a page is empty, the page is inaccessible during
operation. (The exception is the default page which is always available after reset. It might
become unavailable in a configuration that has subpages with no ‘back’ buttons.)
Tally (GPIO) Window
Below the tree window is the tally section of the configuration page.
It has two sections: inputs and outputs. By clicking on one of the input or output buttons, you
can configure the input or output.
(The NV9654 has no actual tally buttons. Instead, these buttons represent the ports of the DB25
connector at the rear of the panel. The buttons are present in the configuration page to allow
you to configure the tally interface.)
If you are interested in configuring the tally interface, read Chapter 6, GPIO , on page 81.
Selection Buttons
Operators use selection buttons to select levels when the panel is in X-Y mode and MD devices
when the panel is in MD mode. Selection buttons also provide feedback (e.g., source and desti-
nation mnemonics on the face of the buttons) when the operator is performing takes.
You may configure any number of selection buttons (on any button page). The selection
buttons can be arranged anywhere on the button page. The selection buttons on any button
page are unrelated to the selection buttons on any other page. Only the selection buttons on
the currently visible page are active at a given time.
You should configure at least one selection button (for feedback). You may configure as many
selection buttons as are suitable for your system. For instance, if your system has a maximum of
12 levels for any device, it might make sense to have 12 selection buttons.
Operators can scroll through multiple pages of levels in X-Y mode and through multiple pages
of devices in MD mode.
