• If you want to display a popup window on one particular full screen window, then try using the
Popup Window option in the Function Key Object. This is particularly useful if you want the OIT
operator to control the ability to display the popup window. If you want the PLC to determine
when to display the popup window, then try using the Direct Window object.
• If you want to display a popup window that can be shown on any full screen window, then try
using the Popup Window option in the Function Key Object. You should place the Function Key
Object in the Fast Selection Window with the Task Bar enabled, (more information is available on
the Task Bar later in this chapter). This will allow the OIT operator access to that popup window
regardless of which full screen window is displayed. If you want to display the popup window only
when some condition in the PLC has occurred, then try using the Direct Window object on the
Common Window, (more about the common window later in this chapter).
• If you want to display one of many possible popup windows on any full screen window, then
try using the Indirect Window object on the Common Window. You can then let the PLC
determine which popup window should be displayed or you can create several Set Word objects to
allow the OIT operator to select which window to look at, (more about the Set Word object in a
succeeding chapter).

Us ing a func tion key to close a win dow

Us ing the Com mon Win dow
Your project might require that some data be displayed on the OIT screen at all times, regardless of which
window(s) are displayed. For example, you may want to display a company logo on the OIT screen at all times, or
you may want to display some critical data or an alarm message which should be seen no matter what windows are
displayed.
Using base windows to display this information requires that you configure every full screen base window with the
same graphics object. The common window however, is a predefined window in the OIT that you can enable to
display this information. When created, the common window always operates in the background as a full screen
window that overlays any full screen base window displayed.
Whenever you create a new project, the common window (Window #4) is automatically created.

close a direct window, turn off the controlling bit. To close an indirect window, write a
