Screen Links
Use the [NEXT] and [PREV] keys to step backward and forward
through this sequence.
Main Menu and Sub-Menu screens list screens that can be accessed by
pressing the assigned numeric key [1] through [8]. A typical Main
Menu screen provides links to individual screens or sub-menus:
In the example above, pressing [2] at the Main Menu displays the
status of a holding tank. Pressing [4] displays a Sub-Menu of the recipe
options.
Advisor Option
Applications can allow screen changes that are controlled by a logic
controller. When the logic controller writes a valid screen number to a
specified Advisor register, the corresponding screen is displayed. The
controller can initiate a screen change based upon a variety of inputs
to the controller. For example, a pressure limit switch can be used to
initiate the display of a pressure control screen. It is the responsibility
of the application designer to document when and what screen
changes may occur.
