Therefore, a Set Word Object on a base window will cover a Rectangle Object on a common window that
occupies the same space even with the Above base screen attribute enabled.
Changing the Active Common Window
Although only one common window can be on the HMI display at one time, you do have the ability to create multiple
common windows by using base windows as common windows. Then, with the help of a Function Key object (using
the Change common window checkbox), the HMI operator can change the active common window.
The ability to change the common window adds more flexibility to your project should you need it. For example, you
may have a series of full screen windows which all need a keypad for entry. Another series of full screen windows may
require a common alarm message. By changing the common window with each series of windows, you can customize
each common window to contain only the graphics objects that are needed.
To change the active common window:
1. Create a common window.
2. Create a base window that is full screen. This will be used as another common window.
 Note that when a base window is used as a common window, the Start Pos:, Style, Frame, and
Background settings are ignored by the HMI. For this example, let’s use Window #30 as the alternate
common window.
3. Create another full screen base window that can be displayed along with the common windows, (such as a
startup window). Let’s use Window #10, the initial window, for our example.
4. On Window #10, create a Function Key object that is used to change the common window. From the Objects
menu, click Function Key. The New Function Key Object dialog box appears.
5. On the General tab, select the Change common window option button.
6. In the same section, select 30 from the Window no. drop down menu.
7. Click the Shape tab. Click Use Shape... and then click on the Shape Library… button. Select Shape #19 from
the Buttons 1 library. Click OK to return to the Create Function Key Object dialog box.
8. Click the Label tab. Click the Use label checkbox.
9. For our example, type CCW (meaning Change Common Window) into the Content box. Click OK to exit the
Create Function Key Object dialog box and go back to the EasyBuilder main screen.
10. Place the new Function Key object somewhere on Window #10.
Below is an illustration of what the default common window, Window#30 (alternate common window), and
Window#10 (startup window) might look like:
