Window Operations - KEP MMI-1500 Installation & Operation Manual

7.4 Window Operations

Every new project begins with a default window, window number 10. Usually more than one window is needed for a project.
There are three types of windows – Base, Fast and Common. Allowable window numbers are from 10 to 1999.
Window types
Base Window:
These are the normal windows displayed during HMI runtime operations. They are used as informational or control screens
that allow the operator manage a process. A PLC control or function key may call them up. They are also used with Direct
and Indirect Window parts to appear on the screen as needed. The possible range of Base window numbers is 10 to 1999
(1 to 1989 if starting window is set to 1).
Fast Selection Window:
The Fast Selection window is activated when the Screen Task Button is pressed. The size is limited to 10 to 200 pixels wide
by 10 to 480 pixels high. It is designated as window number 4 (-5 if starting window is set to 1). See the System Parameters
and Task Bar sections for more details about the Fast Selection window.
Note: Base windows can be reassigned to the Fast Select function through a Function Key with the Jog-FS action.
The Base window replacing the Fast Select window must be the same height and width as the Fast Select window 4.
Common Window:
Common windows are used as foregrounds or backgrounds to Base windows. All controls on the acting Common window
are active. In addition, any objects drawn on the common window and parts with shapes/bitmaps are visible when on top of
the controlling Base window. This saves memory by allowing the programmer to provide a common header or set of controls
that are always active no matter what base screen is called.
The default Common window is window 6 (-5 if starting window is set to 1).
Note: Base windows can be reassigned as the Common window through a Function Key with the Change
Common Window action. Base window numbers 10 to 1999 can also be assigned as Common windows. When called
as Common windows they behave as Common windows by replacing the default Common window (6).
Note: Base windows may be specified as smaller than full screen to facilitate a pop-up operation. These small
windows, when popped up, covers the Common window objects.
