If a popup window is displayed which does not have the monopoly feature enabled, the OIT operator is able to press
any function keys on the popup window or the full screen window since objects on both screens are active.
In this example, the OIT operator is able to press Key1-3 on the full screen window or the switch on Popup
Window#21. If another popup window is displayed that does have the monopoly feature enabled, then Key1-3 on
the full screen window will not respond when pressed.
Please note that the monopoly feature only disables touchscreen objects on the full screen window. The switch on
Popup Window#21 can still be activated, as can any popup window displayed on the full screen.
The monopoly feature can be used to display a popup window with some action that the OIT operator must perform
before being allowed to do some other action on the OIT. For example, you might construct a dialog box that asks
the OIT operator if some step in the control process has been performed. The dialog box would have Yes and No
function key options which, with the monopoly feature enabled, the OIT operator must press before continuing.
As signing Un der lay Win dows
An Underlay Window is a Base Window that is displayed at the same time as the Base Window that calls it. Each
full-size Base Window can display up to three Underlay Windows. A Pop-Up Window cannot display any
Underlay Windows. There may be times when it is desirable to place the same information on multiple (but not all)
windows. Underlay Windows provide a means to accomplish that without the overhead of a Direct or Indirect
Window, and without using the Common Window (which makes the information visible on all windows). Underlay
windows also eliminate the need to actually place the same objects on multiple windows, which increases the
memory required for the project. Each Base Window can display up to three Underlay Windows, which are called
Bottom, Middle, and Top.
